They are never raw DOM references. + * + * **Note:** Keep in mind that this function will not find elements + * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)` + * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`. + * + * ## AngularJS's jqLite + * jqLite provides only the following jQuery methods: + * + * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument + * - [`after()`](http://api.jquery.com/after/) + * - [`append()`](http://api.jquery.com/append/) - Contrary to jQuery, this doesn't clone elements + * so will not work correctly when invoked on a jqLite object containing more than one DOM node + * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters + * - [`bind()`](http://api.jquery.com/bind/) (_deprecated_, use [`on()`](http://api.jquery.com/on/)) - Does not support namespaces, selectors or eventData + * - [`children()`](http://api.jquery.com/children/) - Does not support selectors + * - [`clone()`](http://api.jquery.com/clone/) + * - [`contents()`](http://api.jquery.com/contents/) + * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`. + * As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing. + * - [`data()`](http://api.jquery.com/data/) + * - [`detach()`](http://api.jquery.com/detach/) + * - [`empty()`](http://api.jquery.com/empty/) + * - [`eq()`](http://api.jquery.com/eq/) + * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name + * - [`hasClass()`](http://api.jquery.com/hasClass/) + * - [`html()`](http://api.jquery.com/html/) + * - [`next()`](http://api.jquery.com/next/) - Does not support selectors + * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData + * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter + * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors + * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors + * - [`prepend()`](http://api.jquery.com/prepend/) + * - [`prop()`](http://api.jquery.com/prop/) + * - [`ready()`](http://api.jquery.com/ready/) (_deprecated_, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`) + * - [`remove()`](http://api.jquery.com/remove/) + * - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes + * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument + * - [`removeData()`](http://api.jquery.com/removeData/) + * - [`replaceWith()`](http://api.jquery.com/replaceWith/) + * - [`text()`](http://api.jquery.com/text/) + * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument + * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers + * - [`unbind()`](http://api.jquery.com/unbind/) (_deprecated_, use [`off()`](http://api.jquery.com/off/)) - Does not support namespaces or event object as parameter + * - [`val()`](http://api.jquery.com/val/) + * - [`wrap()`](http://api.jquery.com/wrap/) + * + * ## jQuery/jqLite Extras + * AngularJS also provides the following additional methods and events to both jQuery and jqLite: + * + * ### Events + * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event + * on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM + * element before it is removed. + * + * ### Methods + * - `controller(name)` - retrieves the controller of the current element or its parent. By default + * retrieves controller associated with the `ngController` directive. If `name` is provided as + * camelCase directive name, then the controller for this directive will be retrieved (e.g. + * `'ngModel'`). + * - `injector()` - retrieves the injector of the current element or its parent. + * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current + * element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to + * be enabled. + * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the + * current element. This getter should be used only on elements that contain a directive which starts a new isolate + * scope. Calling `scope()` on this element always returns the original non-isolate scope. + * Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled. + * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top + * parent element is reached. + * + * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See + * https://github.com/angular/angular.js/issues/14251 for more information. + * + * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery. + * @returns {Object} jQuery object. + */ - JQLite.expando = 'ng339'; +JQLite.expando = 'ng339'; - var jqCache = JQLite.cache = {}, - jqId = 1; +var jqCache = JQLite.cache = {}, + jqId = 1; - /* +/* * !!!

In these situations using the array notation to specify the dependencies in - * a way that survives minification is a better choice: - * - * ```js - * // We wish to write this (not minification / obfuscation safe) - * injector.invoke(function($compile, $rootScope) { - * // ... - * }); - * - * // We are forced to write break inlining - * var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) { - * // ... - * }; - * tmpFn.$inject = ['$compile', '$rootScope']; - * injector.invoke(tmpFn); - * - * // To better support inline function the inline annotation is supported - * injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) { - * // ... - * }]); - * - * // Therefore - * expect(injector.annotate( - * ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}]) - * ).toEqual(['$compile', '$rootScope']); - * ``` - * - * @param {Function|Array.} fn Function for which dependent service names need to - * be retrieved as described above. - * - * @param {boolean=} [strictDi=false] Disallow argument name annotation inference. - * - * @returns {Array.} The names of the services which the function requires. - */ - /** - * @ngdoc method - * @name $injector#loadNewModules - * - * @description - * - * **This is a dangerous API, which you use at your own risk!** - * - * Add the specified modules to the current injector. - * - * This method will add each of the injectables to the injector and execute all of the config and run - * blocks for each module passed to the method. - * - * If a module has already been loaded into the injector then it will not be loaded again. - * - * * The application developer is responsible for loading the code containing the modules; and for - * ensuring that lazy scripts are not downloaded and executed more often that desired. - * * Previously compiled HTML will not be affected by newly loaded directives, filters and components. - * * Modules cannot be unloaded. - * - * You can use {@link $injector#modules `$injector.modules`} to check whether a module has been loaded - * into the injector, which may indicate whether the script has been executed already. - * - * @example - * Here is an example of loading a bundle of modules, with a utility method called `getScript`: - * - * ```javascript - * app.factory('loadModule', function($injector) { - * return function loadModule(moduleName, bundleUrl) { - * return getScript(bundleUrl).then(function() { $injector.loadNewModules([moduleName]); }); - * }; - * }) - * ``` - * - * @param {Array=} mods an array of modules to load into the application. - * Each item in the array should be the name of a predefined module or a (DI annotated) - * function that will be invoked by the injector as a `config` block. - * See: {@link angular.module modules} - */ +// if any other type of options value besides an Object value is +// passed into the $animate.method() animation then this helper code +// will be run which will ignore it.

This is a good place to put initialization code for your controller. - * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The - * `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an - * object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a - * component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will - * also be called when your bindings are initialized. - * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on - * changes. Any actions that you wish to take in response to the changes that you detect must be - * invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook - * could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not - * be detected by AngularJS's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments; - * if detecting changes, you must store the previous value(s) for comparison to the current values. - * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing - * external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in - * the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent - * components will have their `$onDestroy()` hook called before child components. - * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link - * function this hook can be used to set up DOM event handlers and do direct DOM manipulation. - * Note that child elements that contain `templateUrl` directives will not have been compiled and linked since - * they are waiting for their template to load asynchronously and their own compilation and linking has been - * suspended until that occurs. - * - * #### Comparison with life-cycle hooks in the new Angular - * The new Angular also uses life-cycle hooks for its components. While the AngularJS life-cycle hooks are similar there are - * some differences that you should be aware of, especially when it comes to moving your code from AngularJS to Angular: - * - * * AngularJS hooks are prefixed with `$`, such as `$onInit`. Angular hooks are prefixed with `ng`, such as `ngOnInit`. - * * AngularJS hooks can be defined on the controller prototype or added to the controller inside its constructor. - * In Angular you can only define hooks on the prototype of the Component class. - * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in AngularJS than you would to - * `ngDoCheck` in Angular. - * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be - * propagated throughout the application. - * Angular does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an - * error or do nothing depending upon the state of `enableProdMode()`. - * - * #### Life-cycle hook examples - * - * This example shows how you can check for mutations to a Date object even though the identity of the object - * has not changed. - * - * - * - * angular.module('do-check-module', []) - * .component('app', { - * template: - * 'Month: ' + - * 'Date: {{ $ctrl.date }}' + - * '', - * controller: function() { - * this.date = new Date(); - * this.month = this.date.getMonth(); - * this.updateDate = function() { - * this.date.setMonth(this.month); - * }; - * } - * }) - * .component('test', { - * bindings: { date: '<' }, - * template: - * '{{ $ctrl.log | json }}', - * controller: function() { - * var previousValue; - * this.log = []; - * this.$doCheck = function() { - * var currentValue = this.date && this.date.valueOf(); - * if (previousValue !== currentValue) { - * this.log.push('doCheck: date mutated: ' + this.date); - * previousValue = currentValue; - * } - * }; - * } - * }); - * - * - * - * - * - * - * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the - * actual identity of the component doesn't change.

The attributes are: - * - * #### `multiElement` - * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between - * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them - * together as the directive elements. It is recommended that this feature be used on directives - * which are not strictly behavioral (such as {@link ngClick}), and which - * do not manipulate or replace child nodes (such as {@link ngInclude}). - * - * #### `priority` - * When there are multiple directives defined on a single DOM element, sometimes it - * is necessary to specify the order in which the directives are applied. The `priority` is used - * to sort the directives before their `compile` functions get called. Priority is defined as a - * number. Directives with greater numerical `priority` are compiled first. Pre-link functions - * are also run in priority order, but post-link functions are run in reverse order. The order - * of directives with the same priority is undefined. The default priority is `0`. - * - * #### `terminal` - * If set to true then the current `priority` will be the last set of directives - * which will execute (any directives at the current priority will still execute - * as the order of execution on same `priority` is undefined). Note that expressions - * and other directives used in the directive's template will also be excluded from execution. - * - * #### `scope` - * The scope property can be `false`, `true`, or an object: - * - * * **`false` (default):** No scope will be created for the directive. The directive will use its - * parent's scope. - * - * * **`true`:** A new child scope that prototypically inherits from its parent will be created for - * the directive's element. If multiple directives on the same element request a new scope, - * only one new scope is created. - * - * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's template. - * The 'isolate' scope differs from normal scope in that it does not prototypically - * inherit from its parent scope. This is useful when creating reusable components, which should not - * accidentally read or modify data in the parent scope. Note that an isolate scope - * directive without a `template` or `templateUrl` will not apply the isolate scope - * to its children elements. - * - * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the - * directive's element. These local properties are useful for aliasing values for templates. The keys in - * the object hash map to the name of the property on the isolate scope; the values define how the property - * is bound to the parent scope, via matching attributes on the directive's element: - * - * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is - * always a string since DOM attributes are strings. If no `attr` name is specified then the - * attribute name is assumed to be the same as the local name. Given `` and the isolate scope definition `scope: { localName:'@myAttr' }`, - * the directive's scope property `localName` will reflect the interpolated value of `hello - * {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's - * scope. The `name` is read from the parent scope (not the directive's scope). - * - * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression - * passed via the attribute `attr`. The expression is evaluated in the context of the parent scope. - * If no `attr` name is specified then the attribute name is assumed to be the same as the local - * name. Given `` and the isolate scope definition `scope: { - * localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the - * value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in - * `localModel` and vice versa. Optional attributes should be marked as such with a question mark: - * `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't - * optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`}) - * will be thrown upon discovering changes to the local value, since it will be impossible to sync - * them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`} - * method is used for tracking changes, and the equality check is based on object identity. - * However, if an object literal or an array literal is passed as the binding expression, the - * equality check is done by value (using the {@link angular.equals} function). It's also possible - * to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection - * `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional). - * - * * `<` or `` and directive definition of - * `scope: { localModel:'` and the isolate scope definition `scope: { - * localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for - * the `count = count + value` expression. Often it's desirable to pass data from the isolated scope - * via an expression to the parent scope. This can be done by passing a map of local variable names - * and values into the expression wrapper fn. For example, if the expression is `increment(amount)` - * then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`. - * - * In general it's possible to apply more than one directive to one element, but there might be limitations - * depending on the type of scope required by the directives. The following points will help explain these limitations. - * For simplicity only two directives are taken into account, but it is also applicable for several directives: - * - * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope - * * **child scope** + **no scope** => Both directives will share one single child scope - * * **child scope** + **child scope** => Both directives will share one single child scope - * * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use - * its parent's scope - * * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot - * be applied to the same element. - * * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives - * cannot be applied to the same element. - * - * - * #### `bindToController` - * This property is used to bind scope properties directly to the controller. It can be either - * `true` or an object hash with the same format as the `scope` property. - * - * When an isolate scope is used for a directive (see above), `bindToController: true` will - * allow a component to have its properties bound to the controller, rather than to scope. - * - * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller - * properties. You can access these bindings once they have been initialized by providing a controller method called - * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings - * initialized. - * - * - * **Deprecation warning:** if `$compileProcvider.preAssignBindingsEnabled(true)` was called, bindings for non-ES6 class - * controllers are bound to `this` before the controller constructor is called but this use is now deprecated. Please - * place initialization code that relies upon bindings inside a `$onInit` method on the controller, instead. - * - * - * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property. - * This will set up the scope bindings to the controller directly. Note that `scope` can still be used - * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate - * scope (useful for component directives). - * - * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`. - * - * - * #### `controller` - * Controller constructor function. The controller is instantiated before the - * pre-linking phase and can be accessed by other directives (see - * `require` attribute). This allows the directives to communicate with each other and augment - * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals: - * - * * `$scope` - Current scope associated with the element - * * `$element` - Current element - * * `$attrs` - Current attributes object for the element - * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope: - * `function([scope], cloneLinkingFn, futureParentElement, slotName)`: - * * `scope`: (optional) override the scope. - * * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content. - * * `futureParentElement` (optional): - * * defines the parent to which the `cloneLinkingFn` will add the cloned elements. - * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`. - * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements) - * and when the `cloneLinkingFn` is passed, - * as those elements need to created and cloned in a special way when they are defined outside their - * usual containers (e.g. like ``). - * * See also the `directive.templateNamespace` property. - * * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`) - * then the default transclusion is provided. - * The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns - * `true` if the specified slot contains content (i.e. one or more DOM nodes). - * - * #### `require` - * Require another directive and inject its controller as the fourth argument to the linking function. The - * `require` property can be a string, an array or an object: - * * a **string** containing the name of the directive to pass to the linking function - * * an **array** containing the names of directives to pass to the linking function. The argument passed to the - * linking function will be an array of controllers in the same order as the names in the `require` property - * * an **object** whose property values are the names of the directives to pass to the linking function. The argument - * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding - * controllers. - * - * If the `require` property is an object and `bindToController` is truthy, then the required controllers are - * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers - * have been constructed but before `$onInit` is called. - * If the name of the required controller is the same as the local name (the key), the name can be - * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`. - * See the {@link $compileProvider#component} helper for an example of how this can be used. - * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is - * raised (unless no link function is specified and the required controllers are not being bound to the directive - * controller, in which case error checking is skipped). The name can be prefixed with: - * - * * (no prefix) - Locate the required controller on the current element. Throw an error if not found. - * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found. - * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found. - * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found. - * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass - * `null` to the `link` fn if not found. - * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass - * `null` to the `link` fn if not found. - * - * - * #### `controllerAs` - * Identifier name for a reference to the controller in the directive's scope. - * This allows the controller to be referenced from the directive template. This is especially - * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible - * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the - * `controllerAs` reference might overwrite a property that already exists on the parent scope. - * - * - * #### `restrict` - * String of subset of `EACM` which restricts the directive to a specific directive - * declaration style. If omitted, the defaults (elements and attributes) are used. - * - * * `E` - Element name (default): `` - * * `A` - Attribute (default): `` - * * `C` - Class: `` - * * `M` - Comment: `` - * - * - * #### `templateNamespace` - * String representing the document type used by the markup in the template. - * AngularJS needs this information as those elements need to be created and cloned - * in a special way when they are defined outside their usual containers like `` and ``. - * - * * `html` - All root nodes in the template are HTML. Root nodes may also be - * top-level elements such as `` or ``. - * * `svg` - The root nodes in the template are SVG elements (excluding ``). - * * `math` - The root nodes in the template are MathML elements (excluding ``). - * - * If no `templateNamespace` is specified, then the namespace is considered to be `html`. - * - * #### `template` - * HTML markup that may: - * * Replace the contents of the directive's element (default). - * * Replace the directive's element itself (if `replace` is true - DEPRECATED). - * * Wrap the contents of the directive's element (if `transclude` is true). - * - * Value may be: - * - * * A string. For example `{{delete_str}}`. - * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile` - * function api below) and returns a string value. - * - * - * #### `templateUrl` - * This is similar to `template` but the template is loaded from the specified URL, asynchronously. - * - * Because template loading is asynchronous the compiler will suspend compilation of directives on that element - * for later when the template has been resolved. In the meantime it will continue to compile and link - * sibling and parent elements as though this element had not contained any directives. - * - * The compiler does not suspend the entire compilation to wait for templates to be loaded because this - * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the - * case when only one deeply nested directive has `templateUrl`. - * - * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache} - * - * You can specify `templateUrl` as a string representing the URL or as a function which takes two - * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns - * a string value representing the url. In either case, the template URL is passed through {@link - * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}. - * - * - * #### `replace` (*DEPRECATED*) - * - * `replace` will be removed in next major release - i.e. v2.0). - * - * Specifies what the template should replace. Defaults to `false`. - * - * * `true` - the template will replace the directive's element. - * * `false` - the template will replace the contents of the directive's element. - * - * The replacement process migrates all of the attributes / classes from the old element to the new - * one. See the {@link guide/directive#template-expanding-directive + * + * #### `multiElement` + * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between + * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them + * together as the directive elements. It is recommended that this feature be used on directives + * which are not strictly behavioral (such as {@link ngClick}), and which + * do not manipulate or replace child nodes (such as {@link ngInclude}). + * + * #### `priority` + * When there are multiple directives defined on a single DOM element, sometimes it + * is necessary to specify the order in which the directives are applied. The `priority` is used + * to sort the directives before their `compile` functions get called. Priority is defined as a + * number. Directives with greater numerical `priority` are compiled first. Pre-link functions + * are also run in priority order, but post-link functions are run in reverse order. The order + * of directives with the same priority is undefined. The default priority is `0`. + * + * #### `terminal` + * If set to true then the current `priority` will be the last set of directives + * which will execute (any directives at the current priority will still execute + * as the order of execution on same `priority` is undefined). Note that expressions + * and other directives used in the directive's template will also be excluded from execution. + * + * #### `scope` + * The scope property can be `false`, `true`, or an object: + * + * * **`false` (default):** No scope will be created for the directive.

In many cases, this is not noticable, but e.g. {@link ngModel} will + * attach `$formatters` and `$parsers` twice. + * + * See issue [#2573](https://github.com/angular/angular.js/issues/2573). + * + * #### `transclude: element` in the replace template root can have unexpected effects + * + * When the replace template has a directive at the root node that uses + * {@link $compile#-transclude- `transclude: element`}, e.g. + * {@link ngIf} or {@link ngRepeat}, the DOM structure or scope inheritance can be incorrect. + * See the following issues: + * + * - Incorrect scope on replaced element: + * [#9837](https://github.com/angular/angular.js/issues/9837) + * - Different DOM between `template` and `templateUrl`: + * [#10612](https://github.com/angular/angular.js/issues/14326) + * + */ + +/** + * @ngdoc directive + * @name ngProp + * @restrict A + * @element ANY + * + * @usage + * + * ```html + * + * + * ``` + * + * or with uppercase letters in property (e.g. "propName"): + * + * + * ```html + * + * + * ``` + * + * + * @description + * The `ngProp` directive binds an expression to a DOM element property. + * `ngProp` allows writing to arbitrary properties by including + * the property name in the attribute, e.g. `ng-prop-value="'my value'"` binds 'my value' to + * the `value` property. + * + * Usually, it's not necessary to write to properties in AngularJS, as the built-in directives + * handle the most common use cases (instead of the above example, you would use {@link ngValue}). + * + * However, [custom elements](https://developer.mozilla.org/docs/Web/Web_Components/Using_custom_elements) + * often use custom properties to hold data, and `ngProp` can be used to provide input to these + * custom elements. + * + * ## Binding to camelCase properties + * + * Since HTML attributes are case-insensitive, camelCase properties like `innerHTML` must be escaped. + * AngularJS uses the underscore (_) in front of a character to indicate that it is uppercase, so + * `innerHTML` must be written as `ng-prop-inner_h_t_m_l="expression"` (Note that this is just an + * example, and for binding HTML {@link ngBindHtml} should be used. + * + * ## Security + * + * Binding expressions to arbitrary properties poses a security risk, as properties like `innerHTML` + * can insert potentially dangerous HTML into the application, e.g. script tags that execute + * malicious code. + * For this reason, `ngProp` applies Strict Contextual Escaping with the {@link ng.$sce $sce service}. + * This means vulnerable properties require their content to be "trusted", based on the + * context of the property. For example, the `innerHTML` is in the `HTML` context, and the + * `iframe.src` property is in the `RESOURCE_URL` context, which requires that values written to + * this property are trusted as a `RESOURCE_URL`. + * + * This can be set explicitly by calling $sce.trustAs(type, value) on the value that is + * trusted before passing it to the `ng-prop-*` directive. There are exist shorthand methods for + * each context type in the form of {@link ng.$sce#trustAsResourceUrl $sce.trustAsResourceUrl()} et al. + * + * In some cases you can also rely upon automatic sanitization of untrusted values - see below. + * + * Based on the context, other options may exist to mark a value as trusted / configure the behavior + * of {@link ng.$sce}. For example, to restrict the `RESOURCE_URL` context to specific origins, use + * the {@link $sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist()} + * and {@link $sceDelegateProvider#resourceUrlBlacklist resourceUrlBlacklist()}. + * + * {@link ng.$sce#what-trusted-context-types-are-supported- Find out more about the different context types}. + * + * ### HTML Sanitization + * + * By default, `$sce` will throw an error if it detects untrusted HTML content, and will not bind the + * content. + * However, if you include the {@link ngSanitize ngSanitize module}, it will try to sanitize the + * potentially dangerous HTML, e.g. strip non-whitelisted tags and attributes when binding to + * `innerHTML`. + * + * @example + * ### Binding to different contexts + * + * + * + * angular.module('exampleNgProp', []) + * .component('main', { + * templateUrl: 'main.html', + * controller: function($sce) { + * this.safeContent = 'Safe content'; + * this.unsafeContent = 'Click for XSS'; + * this.trustedUnsafeContent = $sce.trustAsHtml(this.unsafeContent); + * } + * }); + * + * + * + * + * Binding to a property without security context: + * + * innerText (safeContent) + * + * + * + * "Safe" content that requires a security context will throw because the contents could potentially be dangerous ... + * + * innerHTML (safeContent) + * + * + * + * ... so that actually dangerous content cannot be executed: + * + * innerHTML (unsafeContent) + * + * + * + * ... but unsafe Content that has been trusted explicitly works - only do this if you are 100% sure! + * + * innerHTML (trustedUnsafeContent) + * + * + * + * + * + * + * + * .prop-unit { + * margin-bottom: 10px; + * } + * + * .prop-binding { + * min-height: 30px; + * border: 1px solid blue; + * } + * + * .prop-note { + * font-family: Monospace; + * } + * + * + * + * + * @example + * ### Binding to innerHTML with ngSanitize + * + * + * + * angular.module('exampleNgProp', ['ngSanitize']) + * .component('main', { + * templateUrl: 'main.html', + * controller: function($sce) { + * this.safeContent = 'Safe content'; + * this.unsafeContent = 'Click for XSS'; + * this.trustedUnsafeContent = $sce.trustAsHtml(this.unsafeContent); + * } + * }); + * + * + * + * + * "Safe" content will be sanitized ... + * + * innerHTML (safeContent) + * + * + * + * ... as will dangerous content: + * + * innerHTML (unsafeContent) + * + * + * + * ... and content that has been trusted explicitly works the same as without ngSanitize: + * + * innerHTML (trustedUnsafeContent) + * + * + * + * + * + * + * + * .prop-unit { + * margin-bottom: 10px; + * } + * + * .prop-binding { + * min-height: 30px; + * border: 1px solid blue; + * } + * + * .prop-note { + * font-family: Monospace; + * } + * + * + * + */ + +/** @ngdoc directive + * @name ngOn + * @restrict A + * @element ANY + * + * @usage + * + * ```html + * + * + * ``` + * + * or with uppercase letters in property (e.g. "eventName"): + * + * + * ```html + * + * + * ``` + * + * @description + * The `ngOn` directive adds an event listener to a DOM element via + * {@link angular.element angular.element().on()}, and evaluates an expression when the event is + * fired. + * `ngOn` allows adding listeners for arbitrary events by including + * the event name in the attribute, e.g. `ng-on-drop="onDrop()"` executes the 'onDrop()' expression + * when the `drop` event is fired. + * + * AngularJS provides specific directives for many events, such as {@link ngClick}, so in most + * cases it is not necessary to use `ngOn`.

While for simple usage patterns this doesn't matter much, for advanced usage - * it is important to familiarize yourself with these APIs and the guarantees they provide. - * - * - * ## General usage - * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} — - * that is used to generate an HTTP request and returns a {@link ng.$q promise}. - * - * ```js - * // Simple GET request example: - * $http({ - * method: 'GET', - * url: '/someUrl' - * }).then(function successCallback(response) { - * // this callback will be called asynchronously - * // when the response is available - * }, function errorCallback(response) { - * // called asynchronously if an error occurs - * // or server returns response with an error status. - * }); - * ``` - * - * The response object has these properties: - * - * - **data** – `{string|Object}` – The response body transformed with the transform - * functions. - * - **status** – `{number}` – HTTP status code of the response. - * - **headers** – `{function([headerName])}` – Header getter function. - * - **config** – `{Object}` – The configuration object that was used to generate the request. - * - **statusText** – `{string}` – HTTP status text of the response. - * - **xhrStatus** – `{string}` – Status of the XMLHttpRequest (`complete`, `error`, `timeout` or `abort`). - * - * A response status code between 200 and 299 is considered a success status and will result in - * the success callback being called. Any response status code outside of that range is - * considered an error status and will result in the error callback being called. - * Also, status codes less than -1 are normalized to zero. -1 usually means the request was - * aborted, e.g. using a `config.timeout`. - * Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning - * that the outcome (success or error) will be determined by the final response status code. - * - * - * ## Shortcut methods - * - * Shortcut methods are also available. All shortcut methods require passing in the URL, and - * request data must be passed in for POST/PUT requests. An optional config can be passed as the - * last argument. - * - * ```js - * $http.get('/someUrl', config).then(successCallback, errorCallback); - * $http.post('/someUrl', data, config).then(successCallback, errorCallback); - * ``` - * - * Complete list of shortcut methods: - * - * - {@link ng.$http#get $http.get} - * - {@link ng.$http#head $http.head} - * - {@link ng.$http#post $http.post} - * - {@link ng.$http#put $http.put} - * - {@link ng.$http#delete $http.delete} - * - {@link ng.$http#jsonp $http.jsonp} - * - {@link ng.$http#patch $http.patch} - * - * - * ## Writing Unit Tests that use $http - * When unit testing (using {@link ngMock ngMock}), it is necessary to call - * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending - * request using trained responses. - * - * ``` - * $httpBackend.expectGET(...); - * $http.get(...); - * $httpBackend.flush(); - * ``` - * - * ## Setting HTTP Headers - * - * The $http service will automatically add certain HTTP headers to all requests. These defaults - * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration - * object, which currently contains this default configuration: - * - * - `$httpProvider.defaults.headers.common` (headers that are common for all requests): - * - Accept: application/json, text/plain, \*/\* - * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests) - * - `Content-Type: application/json` - * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests) - * - `Content-Type: application/json` - * - * To add or overwrite these defaults, simply add or remove a property from these configuration - * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object - * with the lowercased HTTP method name as the key, e.g. - * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`. - * - * The defaults can also be set at runtime via the `$http.defaults` object in the same - * fashion. For example: - * - * ``` - * module.run(function($http) { - * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'; - * }); - * ``` - * - * In addition, you can supply a `headers` property in the config object passed when - * calling `$http(config)`, which overrides the defaults without changing them globally. - * - * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis, - * Use the `headers` property, setting the desired header to `undefined`. For example: - * - * ```js - * var req = { - * method: 'POST', - * url: 'http://example.com', - * headers: { - * 'Content-Type': undefined - * }, - * data: { test: 'test' } - * } - * - * $http(req).then(function(){...}, function(){...}); - * ``` - * - * ## Transforming Requests and Responses - * - * Both requests and responses can be transformed using transformation functions: `transformRequest` - * and `transformResponse`. These properties can be a single function that returns - * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions, - * which allows you to `push` or `unshift` a new transformation function into the transformation chain. - * - * - * **Note:** AngularJS does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline. - * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference). - * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest - * function will be reflected on the scope and in any templates where the object is data-bound. - * To prevent this, transform functions should have no side-effects. - * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return. - * - * - * ### Default Transformations - * - * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and - * `defaults.transformResponse` properties. If a request does not provide its own transformations - * then these will be applied. - * - * You can augment or replace the default transformations by modifying these properties by adding to or - * replacing the array. - * - * AngularJS provides the following default transformations: - * - * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`) is - * an array with one function that does the following: - * - * - If the `data` property of the request configuration object contains an object, serialize it - * into JSON format. - * - * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`) is - * an array with one function that does the following: - * - * - If XSRF prefix is detected, strip it (see Security Considerations section below). - * - If the `Content-Type` is `application/json` or the response looks like JSON, - * deserialize it using a JSON parser. - * - * - * ### Overriding the Default Transformations Per Request - * - * If you wish to override the request/response transformations only for a single request then provide - * `transformRequest` and/or `transformResponse` properties on the configuration object passed - * into `$http`. - * - * Note that if you provide these properties on the config object the default transformations will be - * overwritten. If you wish to augment the default transformations then you must include them in your - * local transformation array. - * - * The following code demonstrates adding a new response transformation to be run after the default response - * transformations have been run. - * - * ```js - * function appendTransform(defaults, transform) { - * - * // We can't guarantee that the default transformation is an array - * defaults = angular.isArray(defaults) ? defaults : [defaults]; - * - * // Append the new transformation to the defaults - * return defaults.concat(transform); - * } - * - * $http({ - * url: '...', - * method: 'GET', - * transformResponse: appendTransform($http.defaults.transformResponse, function(value) { - * return doTransform(value); - * }) - * }); - * ``` - * - * - * ## Caching - * - * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must - * set the config.cache value or the default cache value to TRUE or to a cache object (created - * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes - * precedence over the default cache value. - * - * In order to: - * * cache all responses - set the default cache value to TRUE or to a cache object - * * cache a specific response - set config.cache value to TRUE or to a cache object - * - * If caching is enabled, but neither the default cache nor config.cache are set to a cache object, - * then the default `$cacheFactory("$http")` object is used. - * - * The default cache value can be set by updating the - * {@link ng.$http#defaults `$http.defaults.cache`} property or the - * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property. - * - * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using - * the relevant cache object. The next time the same request is made, the response is returned - * from the cache without sending a request to the server. - * - * Take note that: - * - * * Only GET and JSONP requests are cached. - * * The cache key is the request URL including search parameters; headers are not considered. - * * Cached responses are returned asynchronously, in the same way as responses from the server. - * * If multiple identical requests are made using the same cache, which is not yet populated, - * one request will be made to the server and remaining requests will return the same response. - * * A cache-control header on the response does not affect if or how responses are cached. - * - * - * ## Interceptors - * - * Before you start creating interceptors, be sure to understand the - * {@link ng.$q $q and deferred/promise APIs}. - * - * For purposes of global error handling, authentication, or any kind of synchronous or - * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be - * able to intercept requests before they are handed to the server and - * responses before they are handed over to the application code that - * initiated these requests.

The interceptors leverage the {@link ng.$q * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing. - * - * The interceptors are service factories that are registered with the `$httpProvider` by - * adding them to the `$httpProvider.interceptors` array. The factory is called and - * injected with dependencies (if specified) and returns the interceptor. - * - * There are two kinds of interceptors (and two kinds of rejection interceptors): - * - * * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to - * modify the `config` object or create a new one. The function needs to return the `config` - * object directly, or a promise containing the `config` or a new `config` object. - * * `requestError`: interceptor gets called when a previous interceptor threw an error or - * resolved with a rejection. - * * `response`: interceptors get called with http `response` object. The function is free to - * modify the `response` object or create a new one. The function needs to return the `response` - * object directly, or as a promise containing the `response` or a new `response` object. - * * `responseError`: interceptor gets called when a previous interceptor threw an error or - * resolved with a rejection. - * - * - * ```js - * // register the interceptor as a service - * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) { - * return { - * // optional method - * 'request': function(config) { - * // do something on success - * return config; - * }, - * - * // optional method - * 'requestError': function(rejection) { - * // do something on error - * if (canRecover(rejection)) { - * return responseOrNewPromise - * } - * return $q.reject(rejection); - * }, - * - * - * - * // optional method - * 'response': function(response) { - * // do something on success - * return response; - * }, - * - * // optional method - * 'responseError': function(rejection) { - * // do something on error - * if (canRecover(rejection)) { - * return responseOrNewPromise - * } - * return $q.reject(rejection); - * } - * }; - * }); - * - * $httpProvider.interceptors.push('myHttpInterceptor'); - * - * - * // alternatively, register the interceptor via an anonymous factory - * $httpProvider.interceptors.push(function($q, dependency1, dependency2) { - * return { - * 'request': function(config) { - * // same as above - * }, - * - * 'response': function(response) { - * // same as above - * } - * }; - * }); - * ``` - * - * ## Security Considerations - * - * When designing web applications, consider security threats from: - * - * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) - * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) - * - * Both server and the client must cooperate in order to eliminate these threats. AngularJS comes - * pre-configured with strategies that address these issues, but for this to work backend server - * cooperation is required. - * - * ### JSON Vulnerability Protection - * - * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) - * allows third party website to turn your JSON resource URL into - * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To - * counter this your server can prefix all JSON requests with following string `")]}',\n"`. - * AngularJS will automatically strip the prefix before processing it as JSON. - * - * For example if your server needs to return: - * ```js - * ['one','two'] - * ``` - * - * which is vulnerable to attack, your server can return: - * ```js - * )]}', - * ['one','two'] - * ``` - * - * AngularJS will strip the prefix, before processing the JSON. - * - * - * ### Cross Site Request Forgery (XSRF) Protection - * - * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by - * which the attacker can trick an authenticated user into unknowingly executing actions on your - * website. AngularJS provides a mechanism to counter XSRF. When performing XHR requests, the - * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP - * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the - * cookie, your server can be assured that the XHR came from JavaScript running on your domain. - * The header will not be set for cross-domain requests. - * - * To take advantage of this, your server needs to set a token in a JavaScript readable session - * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the - * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure - * that only JavaScript running on your domain could have sent the request. The token must be - * unique for each user and must be verifiable by the server (to prevent the JavaScript from - * making up its own tokens). We recommend that the token is a digest of your site's - * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography)) - * for added security. - * - * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName - * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time, - * or the per-request config object. - * - * In order to prevent collisions in environments where multiple AngularJS apps share the - * same domain or subdomain, we recommend that each application uses unique cookie name. - * - * @param {object} config Object describing the request to be made and how it should be - * processed. The object has following properties: - * - * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc) - * - **url** – `{string|TrustedObject}` – Absolute or relative URL of the resource that is being requested; - * or an object created by a call to `$sce.trustAsResourceUrl(url)`. - * - **params** – `{Object.}` – Map of strings or objects which will be serialized - * with the `paramSerializer` and appended as GET parameters. - * - **data** – `{string|Object}` – Data to be sent as the request message data. - * - **headers** – `{Object}` – Map of strings or functions which return strings representing - * HTTP headers to send to the server. If the return value of a function is null, the - * header will not be sent. Functions accept a config object as an argument. - * - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object. - * To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`. - * The handler will be called in the context of a `$apply` block. - * - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload - * object.

The transform function takes the http - * request body and headers and returns its transformed (typically serialized) version. - * See {@link ng.$http#overriding-the-default-transformations-per-request + * + * The interceptors are service factories that are registered with the `$httpProvider` by + * adding them to the `$httpProvider.interceptors` array. The factory is called and + * injected with dependencies (if specified) and returns the interceptor. + * + * There are two kinds of interceptors (and two kinds of rejection interceptors): + * + * * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to + * modify the `config` object or create a new one. The function needs to return the `config` + * object directly, or a promise containing the `config` or a new `config` object. + * * `requestError`: interceptor gets called when a previous interceptor threw an error or + * resolved with a rejection. + * * `response`: interceptors get called with http `response` object. The function is free to + * modify the `response` object or create a new one. The function needs to return the `response` + * object directly, or as a promise containing the `response` or a new `response` object. + * * `responseError`: interceptor gets called when a previous interceptor threw an error or + * resolved with a rejection. + * + * + * ```js + * // register the interceptor as a service + * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) { + * return { + * // optional method + * 'request': function(config) { + * // do something on success + * return config; + * }, + * + * // optional method + * 'requestError': function(rejection) { + * // do something on error + * if (canRecover(rejection)) { + * return responseOrNewPromise + * } + * return $q.reject(rejection); + * }, + * + * + * + * // optional method + * 'response': function(response) { + * // do something on success + * return response; + * }, + * + * // optional method + * 'responseError': function(rejection) { + * // do something on error + * if (canRecover(rejection)) { + * return responseOrNewPromise + * } + * return $q.reject(rejection); + * } + * }; + * }); + * + * $httpProvider.interceptors.push('myHttpInterceptor'); + * + * + * // alternatively, register the interceptor via an anonymous factory + * $httpProvider.interceptors.push(function($q, dependency1, dependency2) { + * return { + * 'request': function(config) { + * // same as above + * }, + * + * 'response': function(response) { + * // same as above + * } + * }; + * }); + * ``` + * + * ## Security Considerations + * + * When designing web applications, consider security threats from: + * + * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) + * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) + * + * Both server and the client must cooperate in order to eliminate these threats. AngularJS comes + * pre-configured with strategies that address these issues, but for this to work backend server + * cooperation is required. + * + * ### JSON Vulnerability Protection + * + * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) + * allows third party website to turn your JSON resource URL into + * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To + * counter this your server can prefix all JSON requests with following string `")]}',\n"`. + * AngularJS will automatically strip the prefix before processing it as JSON. + * + * For example if your server needs to return: + * ```js + * ['one','two'] + * ``` + * + * which is vulnerable to attack, your server can return: + * ```js + * )]}', + * ['one','two'] + * ``` + * + * AngularJS will strip the prefix, before processing the JSON. + * + * + * ### Cross Site Request Forgery (XSRF) Protection + * + * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by + * which the attacker can trick an authenticated user into unknowingly executing actions on your + * website. AngularJS provides a mechanism to counter XSRF. When performing XHR requests, the + * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP + * header (by default `X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read + * the cookie, your server can be assured that the XHR came from JavaScript running on your + * domain. + * + * To take advantage of this, your server needs to set a token in a JavaScript readable session + * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the + * server can verify that the cookie matches the `X-XSRF-TOKEN` HTTP header, and therefore be + * sure that only JavaScript running on your domain could have sent the request. The token must + * be unique for each user and must be verifiable by the server (to prevent the JavaScript from + * making up its own tokens). We recommend that the token is a digest of your site's + * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography)) + * for added security. + * + * The header will — by default — **not** be set for cross-domain requests. This + * prevents unauthorized servers (e.g. malicious or compromised 3rd-party APIs) from gaining + * access to your users' XSRF tokens and exposing them to Cross Site Request Forgery. If you + * want to, you can whitelist additional origins to also receive the XSRF token, by adding them + * to {@link ng.$httpProvider#xsrfWhitelistedOrigins xsrfWhitelistedOrigins}. This might be + * useful, for example, if your application, served from `example.com`, needs to access your API + * at `api.example.com`. + * See {@link ng.$httpProvider#xsrfWhitelistedOrigins $httpProvider.xsrfWhitelistedOrigins} for + * more details. + * + * + * **Warning** + * Only whitelist origins that you have control over and make sure you understand the + * implications of doing so. + * + * + * The name of the cookie and the header can be specified using the `xsrfCookieName` and + * `xsrfHeaderName` properties of either `$httpProvider.defaults` at config-time, + * `$http.defaults` at run-time, or the per-request config object. + * + * In order to prevent collisions in environments where multiple AngularJS apps share the + * same domain or subdomain, we recommend that each application uses a unique cookie name. + * + * + * @param {object} config Object describing the request to be made and how it should be + * processed.

This is similar to the native Promise implementation from ES6, + * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise). + * + * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are + * available yet. + * + * It can be used like so: + * + * ```js + * // for the purpose of this example let's assume that variables `$q` and `okToGreet` + * // are available in the current lexical scope (they could have been injected or passed in). + * + * function asyncGreet(name) { + * // perform some asynchronous operation, resolve or reject the promise when appropriate. + * return $q(function(resolve, reject) { + * setTimeout(function() { + * if (okToGreet(name)) { + * resolve('Hello, ' + name + '!'); + * } else { + * reject('Greeting ' + name + ' is not allowed.'); + * } + * }, 1000); + * }); + * } + * + * var promise = asyncGreet('Robin Hood'); + * promise.then(function(greeting) { + * alert('Success: ' + greeting); + * }, function(reason) { + * alert('Failed: ' + reason); + * }); + * ``` + * + * Note: progress/notify callbacks are not currently supported via the ES6-style interface. + * + * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise. + * + * However, the more traditional CommonJS-style usage is still available, and documented below. + * + * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an + * interface for interacting with an object that represents the result of an action that is + * performed asynchronously, and may or may not be finished at any given point in time. + * + * From the perspective of dealing with error handling, deferred and promise APIs are to + * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming. + * + * ```js + * // for the purpose of this example let's assume that variables `$q` and `okToGreet` + * // are available in the current lexical scope (they could have been injected or passed in). + * + * function asyncGreet(name) { + * var deferred = $q.defer(); + * + * setTimeout(function() { + * deferred.notify('About to greet ' + name + '.'); + * + * if (okToGreet(name)) { + * deferred.resolve('Hello, ' + name + '!'); + * } else { + * deferred.reject('Greeting ' + name + ' is not allowed.'); + * } + * }, 1000); + * + * return deferred.promise; + * } + * + * var promise = asyncGreet('Robin Hood'); + * promise.then(function(greeting) { + * alert('Success: ' + greeting); + * }, function(reason) { + * alert('Failed: ' + reason); + * }, function(update) { + * alert('Got notification: ' + update); + * }); + * ``` + * + * At first it might not be obvious why this extra complexity is worth the trouble. The payoff + * comes in the way of guarantees that promise and deferred APIs make, see + * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md. + * + * Additionally the promise api allows for composition that is very hard to do with the + * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach. + * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the + * section on serial or parallel joining of promises. + * + * ## The Deferred API + * + * A new instance of deferred is constructed by calling `$q.defer()`. + * + * The purpose of the deferred object is to expose the associated Promise instance as well as APIs + * that can be used for signaling the successful or unsuccessful completion, as well as the status + * of the task. + * + * **Methods** + * + * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection + * constructed via `$q.reject`, the promise will be rejected instead. + * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to + * resolving it with a rejection constructed via `$q.reject`. + * - `notify(value)` - provides updates on the status of the promise's execution. This may be called + * multiple times before the promise is either resolved or rejected. + * + * **Properties** + * + * - promise – `{Promise}` – promise object associated with this deferred. + * + * + * ## The Promise API + * + * A new promise instance is created when a deferred instance is created and can be retrieved by + * calling `deferred.promise`. + * + * The purpose of the promise object is to allow for interested parties to get access to the result + * of the deferred task when it completes. + * + * **Methods** + * + * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or + * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously + * as soon as the result is available. The callbacks are called with a single argument: the result + * or rejection reason. Additionally, the notify callback may be called zero or more times to + * provide a progress indication, before the promise is resolved or rejected. + * + * This method *returns a new promise* which is resolved or rejected via the return value of the + * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved + * with the value which is resolved in that promise using + * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)). + * It also notifies via the return value of the `notifyCallback` method. The promise cannot be + * resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback + * arguments are optional. + * + * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)` + * + * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise, + * but to do so without modifying the final value. This is useful to release resources or do some + * clean-up that needs to be done whether the promise was rejected or resolved. See the [full + * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for + * more information. + * + * ## Chaining promises + * + * Because calling the `then` method of a promise returns a new derived promise, it is easily + * possible to create a chain of promises: + * + * ```js + * promiseB = promiseA.then(function(result) { + * return result + 1; + * }); + * + * // promiseB will be resolved immediately after promiseA is resolved and its value + * // will be the result of promiseA incremented by 1 + * ``` + * + * It is possible to create chains of any length and since a promise can be resolved with another + * promise (which will defer its resolution further), it is possible to pause/defer resolution of + * the promises at any point in the chain. This makes it possible to implement powerful APIs like + * $http's response interceptors. + * + * + * ## Differences between Kris Kowal's Q and $q + * + * There are two main differences: + * + * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation + * mechanism in AngularJS, which means faster propagation of resolution or rejection into your + * models and avoiding unnecessary browser repaints, which would result in flickering UI. + * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains + * all the important functionality needed for common async tasks. + * + * ## Testing + * + * ```js + * it('should simulate promise', inject(function($q, $rootScope) { + * var deferred = $q.defer(); + * var promise = deferred.promise; + * var resolvedValue; + * + * promise.then(function(value) { resolvedValue = value; }); + * expect(resolvedValue).toBeUndefined(); + * + * // Simulate resolving of promise + * deferred.resolve(123); + * // Note that the 'then' function does not get called synchronously. + * // This is because we want the promise API to always be async, whether or not + * // it got called synchronously or asynchronously. + * expect(resolvedValue).toBeUndefined(); + * + * // Propagate promise resolution to 'then' functions using $apply(). + * $rootScope.$apply(); + * expect(resolvedValue).toEqual(123); + * })); + * ``` + * + * @param {function(function, function)} resolver Function which is responsible for resolving or + * rejecting the newly created promise.

To save the value of the object for + * later comparison, the {@link angular.copy} function is used. This therefore means that + * watching complex objects will have adverse memory and performance implications. + * - This should not be used to watch for changes in objects that are (or contain) + * [File](https://developer.mozilla.org/docs/Web/API/File) objects due to limitations with {@link angular.copy `angular.copy`}. + * - The watch `listener` may change the model, which may trigger other `listener`s to fire. + * This is achieved by rerunning the watchers until no changes are detected. The rerun + * iteration limit is 10 to prevent an infinite loop deadlock. + * + * + * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called, + * you can register a `watchExpression` function with no `listener`. (Be prepared for + * multiple calls to your `watchExpression` because it will execute multiple times in a + * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.) + * + * After a watcher is registered with the scope, the `listener` fn is called asynchronously + * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the + * watcher. In rare cases, this is undesirable because the listener is called when the result + * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you + * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the + * listener was called due to initialization. + * + * + * + * @example + * ```js + // let's assume that scope was dependency injected as the $rootScope + var scope = $rootScope; + scope.name = 'misko'; + scope.counter = 0; + + expect(scope.counter).toEqual(0); + scope.$watch('name', function(newValue, oldValue) { + scope.counter = scope.counter + 1; + }); + expect(scope.counter).toEqual(0); - getStringValue: function(item) { - this.assign(item, 'getStringValue(' + item + ')'); - }, + scope.$digest(); + // the listener is always called during the first $digest loop after it was registered + expect(scope.counter).toEqual(1); - lazyRecurse: function(ast, intoId, nameId, recursionFn, create, skipWatchIdCheck) { - var self = this; - return function() { - self.recurse(ast, intoId, nameId, recursionFn, create, skipWatchIdCheck); - }; - }, + scope.$digest(); + // but now it will not be called unless the value changes + expect(scope.counter).toEqual(1); - lazyAssign: function(id, value) { - var self = this; - return function() { - self.assign(id, value); - }; - }, + scope.name = 'adam'; + scope.$digest(); + expect(scope.counter).toEqual(2); - stringEscapeRegex: /[^ a-zA-Z0-9]/g, - stringEscapeFn: function(c) { - return '\\u' + ('0000' + c.charCodeAt(0).toString(16)).slice(-4); - }, - escape: function(value) { - if (isString(value)) return '\'' + value.replace(this.stringEscapeRegex, this.stringEscapeFn) + '\''; - if (isNumber(value)) return value.toString(); - if (value === true) return 'true'; - if (value === false) return 'false'; - if (value === null) return 'null'; - if (typeof value === 'undefined') return 'undefined'; + // Using a function as a watchExpression + var food; + scope.foodCounter = 0; + expect(scope.foodCounter).toEqual(0); + scope.$watch( + // This function returns the value being watched.

This is similar to the native Promise implementation from ES6, - * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise). - * - * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are - * available yet. - * - * It can be used like so: - * - * ```js - * // for the purpose of this example let's assume that variables `$q` and `okToGreet` - * // are available in the current lexical scope (they could have been injected or passed in). - * - * function asyncGreet(name) { - * // perform some asynchronous operation, resolve or reject the promise when appropriate. - * return $q(function(resolve, reject) { - * setTimeout(function() { - * if (okToGreet(name)) { - * resolve('Hello, ' + name + '!'); - * } else { - * reject('Greeting ' + name + ' is not allowed.'); - * } - * }, 1000); - * }); - * } - * - * var promise = asyncGreet('Robin Hood'); - * promise.then(function(greeting) { - * alert('Success: ' + greeting); - * }, function(reason) { - * alert('Failed: ' + reason); - * }); - * ``` - * - * Note: progress/notify callbacks are not currently supported via the ES6-style interface. - * - * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise. - * - * However, the more traditional CommonJS-style usage is still available, and documented below. - * - * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an - * interface for interacting with an object that represents the result of an action that is - * performed asynchronously, and may or may not be finished at any given point in time. - * - * From the perspective of dealing with error handling, deferred and promise APIs are to - * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming. - * - * ```js - * // for the purpose of this example let's assume that variables `$q` and `okToGreet` - * // are available in the current lexical scope (they could have been injected or passed in). - * - * function asyncGreet(name) { - * var deferred = $q.defer(); - * - * setTimeout(function() { - * deferred.notify('About to greet ' + name + '.'); - * - * if (okToGreet(name)) { - * deferred.resolve('Hello, ' + name + '!'); - * } else { - * deferred.reject('Greeting ' + name + ' is not allowed.'); - * } - * }, 1000); - * - * return deferred.promise; - * } - * - * var promise = asyncGreet('Robin Hood'); - * promise.then(function(greeting) { - * alert('Success: ' + greeting); - * }, function(reason) { - * alert('Failed: ' + reason); - * }, function(update) { - * alert('Got notification: ' + update); - * }); - * ``` - * - * At first it might not be obvious why this extra complexity is worth the trouble. The payoff - * comes in the way of guarantees that promise and deferred APIs make, see - * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md. - * - * Additionally the promise api allows for composition that is very hard to do with the - * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach. - * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the - * section on serial or parallel joining of promises. - * - * ## The Deferred API - * - * A new instance of deferred is constructed by calling `$q.defer()`. - * - * The purpose of the deferred object is to expose the associated Promise instance as well as APIs - * that can be used for signaling the successful or unsuccessful completion, as well as the status - * of the task. - * - * **Methods** - * - * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection - * constructed via `$q.reject`, the promise will be rejected instead. - * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to - * resolving it with a rejection constructed via `$q.reject`. - * - `notify(value)` - provides updates on the status of the promise's execution. This may be called - * multiple times before the promise is either resolved or rejected. - * - * **Properties** - * - * - promise – `{Promise}` – promise object associated with this deferred. - * - * - * ## The Promise API - * - * A new promise instance is created when a deferred instance is created and can be retrieved by - * calling `deferred.promise`. - * - * The purpose of the promise object is to allow for interested parties to get access to the result - * of the deferred task when it completes. - * - * **Methods** - * - * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or - * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously - * as soon as the result is available. The callbacks are called with a single argument: the result - * or rejection reason. Additionally, the notify callback may be called zero or more times to - * provide a progress indication, before the promise is resolved or rejected. - * - * This method *returns a new promise* which is resolved or rejected via the return value of the - * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved - * with the value which is resolved in that promise using - * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)). - * It also notifies via the return value of the `notifyCallback` method. The promise cannot be - * resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback - * arguments are optional. - * - * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)` - * - * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise, - * but to do so without modifying the final value. This is useful to release resources or do some - * clean-up that needs to be done whether the promise was rejected or resolved. See the [full - * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for - * more information. - * - * ## Chaining promises - * - * Because calling the `then` method of a promise returns a new derived promise, it is easily - * possible to create a chain of promises: - * - * ```js - * promiseB = promiseA.then(function(result) { - * return result + 1; - * }); - * - * // promiseB will be resolved immediately after promiseA is resolved and its value - * // will be the result of promiseA incremented by 1 - * ``` - * - * It is possible to create chains of any length and since a promise can be resolved with another - * promise (which will defer its resolution further), it is possible to pause/defer resolution of - * the promises at any point in the chain. This makes it possible to implement powerful APIs like - * $http's response interceptors. - * - * - * ## Differences between Kris Kowal's Q and $q - * - * There are two main differences: - * - * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation - * mechanism in AngularJS, which means faster propagation of resolution or rejection into your - * models and avoiding unnecessary browser repaints, which would result in flickering UI. - * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains - * all the important functionality needed for common async tasks. - * - * ## Testing - * - * ```js - * it('should simulate promise', inject(function($q, $rootScope) { - * var deferred = $q.defer(); - * var promise = deferred.promise; - * var resolvedValue; - * - * promise.then(function(value) { resolvedValue = value; }); - * expect(resolvedValue).toBeUndefined(); - * - * // Simulate resolving of promise - * deferred.resolve(123); - * // Note that the 'then' function does not get called synchronously. - * // This is because we want the promise API to always be async, whether or not - * // it got called synchronously or asynchronously. - * expect(resolvedValue).toBeUndefined(); - * - * // Propagate promise resolution to 'then' functions using $apply(). - * $rootScope.$apply(); - * expect(resolvedValue).toEqual(123); - * })); - * ``` - * - * @param {function(function, function)} resolver Function which is responsible for resolving or - * rejecting the newly created promise. The first parameter is a function which resolves the - * promise, the second parameter is a function which rejects the promise. - * - * @returns {Promise} The newly created promise. - */ - /** - * @ngdoc provider - * @name $qProvider - * @this - * - * @description - */ - function $QProvider() { - var errorOnUnhandledRejections = true; - this.$get = ['$rootScope', '$exceptionHandler', function($rootScope, $exceptionHandler) { - return qFactory(function(callback) { - $rootScope.$evalAsync(callback); - }, $exceptionHandler, errorOnUnhandledRejections); - }]; + function clearPhase() { + $rootScope.$$phase = null; + } - /** - * @ngdoc method - * @name $qProvider#errorOnUnhandledRejections - * @kind function - * - * @description - * Retrieves or overrides whether to generate an error when a rejected promise is not handled. - * This feature is enabled by default. - * - * @param {boolean=} value Whether to generate an error when a rejected promise is not handled. - * @returns {boolean|ng.$qProvider} Current value when called without a new value or self for - * chaining otherwise. - */ - this.errorOnUnhandledRejections = function(value) { - if (isDefined(value)) { - errorOnUnhandledRejections = value; - return this; - } else { - return errorOnUnhandledRejections; - } - }; + function incrementWatchersCount(current, count) { + do { + current.$$watchersCount += count; + } while ((current = current.$parent)); } - /** @this */ - function $$QProvider() { - var errorOnUnhandledRejections = true; - this.$get = ['$browser', '$exceptionHandler', function($browser, $exceptionHandler) { - return qFactory(function(callback) { - $browser.defer(callback); - }, $exceptionHandler, errorOnUnhandledRejections); - }]; + function decrementListenerCount(current, count, name) { + do { + current.$$listenerCount[name] -= count; - this.errorOnUnhandledRejections = function(value) { - if (isDefined(value)) { - errorOnUnhandledRejections = value; - return this; - } else { - return errorOnUnhandledRejections; - } - }; + if (current.$$listenerCount[name] === 0) { + delete current.$$listenerCount[name]; + } + } while ((current = current.$parent)); } /** - * Constructs a promise manager. - * - * @param {function(function)} nextTick Function for executing functions in the next turn. - * @param {function(...*)} exceptionHandler Function into which unexpected exceptions are passed for - * debugging purposes. - * @param {boolean=} errorOnUnhandledRejections Whether an error should be generated on unhandled - * promises rejections. - * @returns {object} Promise manager. + * function used as an initial value for watchers. + * because it's unique we can easily tell it apart from other values */ - function qFactory(nextTick, exceptionHandler, errorOnUnhandledRejections) { - var $qMinErr = minErr('$q', TypeError); - var queueSize = 0; - var checkQueue = []; + function initWatchVal() {} - /** - * @ngdoc method - * @name ng.$q#defer - * @kind function - * - * @description - * Creates a `Deferred` object which represents a task which will finish in the future. - * - * @returns {Deferred} Returns a new instance of deferred. - */ - function defer() { - return new Deferred(); + function flushApplyAsync() { + while (applyAsyncQueue.length) { + try { + applyAsyncQueue.shift()(); + } catch (e) { + $exceptionHandler(e); } + } + applyAsyncId = null; + } - function Deferred() { - var promise = this.promise = new Promise(); - //Non prototype methods necessary to support unbound execution :/ - this.resolve = function(val) { resolvePromise(promise, val); }; - this.reject = function(reason) { rejectPromise(promise, reason); }; - this.notify = function(progress) { notifyPromise(promise, progress); }; - } + function scheduleApplyAsync() { + if (applyAsyncId === null) { + applyAsyncId = $browser.defer(function() { + $rootScope.$apply(flushApplyAsync); + }, null, '$applyAsync'); + } + } + }]; +} +/** + * @ngdoc service + * @name $rootElement + * + * @description + * The root element of AngularJS application.

Its goal is to assist in writing code in a way that (a) is secure by default, and + * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier. + * + * ### Overview + * + * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in + * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically + * run security checks on them (sanitizations, whitelists, depending on context), or throw when it + * cannot guarantee the security of the result. That behavior depends strongly on contexts: HTML + * can be sanitized, but template URLs cannot, for instance. + * + * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML: + * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it + * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and + * render the input as-is, you will need to mark it as trusted for that context before attempting + * to bind it. + * + * As of version 1.2, AngularJS ships with SCE enabled by default. + * + * ### In practice + * + * Here's an example of a binding in a privileged context: + * + * ``` + * + * + * ``` + * + * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE + * disabled, this application allows the user to render arbitrary HTML into the DIV, which would + * be an XSS security bug. In a more realistic example, one may be rendering user comments, blog + * articles, etc. via bindings. (HTML is just one example of a context where rendering user + * controlled input creates security vulnerabilities.) + * + * For the case of HTML, you might use a library, either on the client side, or on the server side, + * to sanitize unsafe HTML before binding to the value and rendering it in the document. + * + * How would you ensure that every place that used these types of bindings was bound to a value that + * was sanitized by your library (or returned as safe for rendering by your server?) How can you + * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some + * properties/fields and forgot to update the binding to the sanitized value? + * + * To be secure by default, AngularJS makes sure bindings go through that sanitization, or + * any similar validation process, unless there's a good reason to trust the given value in this + * context. That trust is formalized with a function call. This means that as a developer, you + * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues, + * you just need to ensure the values you mark as trusted indeed are safe - because they were + * received from your server, sanitized by your library, etc. You can organize your codebase to + * help with this - perhaps allowing only the files in a specific directory to do this. + * Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then + * becomes a more manageable task. + * + * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs} + * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to + * build the trusted versions of your values. + * + * ### How does it work? + * + * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted + * $sce.getTrusted(context, value)} rather than to the value directly. Think of this function as + * a way to enforce the required security context in your data sink. Directives use {@link + * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs + * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also, + * when binding without directives, AngularJS will understand the context of your bindings + * automatically. + * + * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link + * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly + * simplified): + * + * ``` + * var ngBindHtmlDirective = ['$sce', function($sce) { + * return function(scope, element, attr) { + * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) { + * element.html(value || ''); + * }); + * }; + * }]; + * ``` + * + * ### Impact on loading templates + * + * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as + * `templateUrl`'s specified by {@link guide/directive directives}. + * + * By default, AngularJS only loads templates from the same domain and protocol as the application + * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl + * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or + * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist + * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value. + * + * *Please note*: + * The browser's + * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest) + * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/) + * policy apply in addition to this and may further restrict whether the template is successfully + * loaded. This means that without the right CORS policy, loading templates from a different domain + * won't work on all browsers. Also, loading templates from `file://` URL does not work on some + * browsers. + * + * ### This feels like too much overhead + * + * It's important to remember that SCE only applies to interpolation expressions. + * + * If your expressions are constant literals, they're automatically trusted and you don't need to + * call `$sce.trustAs` on them (e.g. + * ``) just works (remember to include the + * `ngSanitize` module). The `$sceDelegate` will also use the `$sanitize` service if it is available + * when binding untrusted values to `$sce.HTML` context. + * AngularJS provides an implementation in `angular-sanitize.js`, and if you + * wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in + * your application. + * + * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load + * templates in `ng-include` from your application's domain without having to even know about SCE. + * It blocks loading templates from other domains or loading templates over http from an https + * served document. You can change these by setting your own custom {@link + * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link + * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs. + * + * This significantly reduces the overhead. It is far easier to pay the small overhead and have an + * application that's secure and can be audited to verify that with much more ease than bolting + * security onto an application later. + * + * + * ### What trusted context types are supported? + * + * | Context | Notes | + * |---------------------|----------------| + * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. | + * | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. | + * | `$sce.MEDIA_URL` | For URLs that are safe to render as media. Is automatically converted from string by sanitizing when needed. | + * | `$sce.URL` | For URLs that are safe to follow as links. Is automatically converted from string by sanitizing when needed. Note that `$sce.URL` makes a stronger statement about the URL than `$sce.MEDIA_URL` does and therefore contexts requiring values trusted for `$sce.URL` can be used anywhere that values trusted for `$sce.MEDIA_URL` are required.| + * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application. Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.) Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` or `$sce.MEDIA_URL` do and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` or `$sce.MEDIA_URL` are required. The {@link $sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider#resourceUrlWhitelist()} and {@link $sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider#resourceUrlBlacklist()} can be used to restrict trusted origins for `RESOURCE_URL` | + * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. | + * + * + * + * Be aware that, before AngularJS 1.7.0, `a[href]` and `img[src]` used to sanitize their + * interpolated values directly rather than rely upon {@link ng.$sce#getTrusted `$sce.getTrusted`}. + * + * **As of 1.7.0, this is no longer the case.** + * + * Now such interpolations are marked as requiring `$sce.URL` (for `a[href]`) or `$sce.MEDIA_URL` + * (for `img[src]`), so that the sanitization happens (via `$sce.getTrusted...`) when the `$interpolate` + * service evaluates the expressions. + * + * + * There are no CSS or JS context bindings in AngularJS currently, so their corresponding `$sce.trustAs` + * functions aren't useful yet. This might evolve. + * + * ### Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} + * + * Each element in these arrays must be one of the following: + * + * - **'self'** + * - The special **string**, `'self'`, can be used to match against all URLs of the **same + * domain** as the application document using the **same protocol**. + * - **String** (except the special value `'self'`) + * - The string is matched against the full *normalized / absolute URL* of the resource + * being tested (substring matches are not good enough.) + * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters + * match themselves. + * - `*`: matches zero or more occurrences of any character other than one of the following 6 + * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use + * in a whitelist. + * - `**`: matches zero or more occurrences of *any* character. As such, it's not + * appropriate for use in a scheme, domain, etc. as it would match too much. (e.g. + * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might + * not have been the intention.) Its usage at the very end of the path is ok. (e.g. + * http://foo.example.com/templates/**). + * - **RegExp** (*see caveat below*) + * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax + * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to + * accidentally introduce a bug when one updates a complex expression (imho, all regexes should + * have good test coverage). For instance, the use of `.` in the regex is correct only in a + * small number of cases. A `.` character in the regex used when matching the scheme or a + * subdomain could be matched against a `:` or literal `.` that was likely not intended. It + * is highly recommended to use the string patterns and only fall back to regular expressions + * as a last resort. + * - The regular expression must be an instance of RegExp (i.e. not a string.) It is + * matched against the **entire** *normalized / absolute URL* of the resource being tested + * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags + * present on the RegExp (such as multiline, global, ignoreCase) are ignored. + * - If you are generating your JavaScript from some other templating engine (not + * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)), + * remember to escape your regular expression (and be aware that you might need more than + * one level of escaping depending on your templating engine and the way you interpolated + * the value.) Do make use of your platform's escaping mechanism as it might be good + * enough before coding your own. E.g. Ruby has + * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape) + * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape). + * Javascript lacks a similar built in function for escaping. Take a look at Google + * Closure library's [goog.string.regExpEscape(s)]( + * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962). + * + * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example. + * + * ### Show me an example using SCE. + * + * + * + * + * + * User comments + * By default, HTML that isn't explicitly trusted (e.g. Alice's comment) is sanitized when + * $sanitize is available. If $sanitize isn't available, this results in an error instead of an + * exploit. + * + * + * {{userComment.name}}: + * + * + * + * + * + * + * + * + * angular.module('mySceApp', ['ngSanitize']) + * .controller('AppController', ['$http', '$templateCache', '$sce', + * function AppController($http, $templateCache, $sce) { + * var self = this; + * $http.get('test_data.json', {cache: $templateCache}).then(function(response) { + * self.userComments = response.data; + * }); + * self.explicitlyTrustedHtml = $sce.trustAsHtml( + * 'Hover over this text.'); + * }]); + * + * + * + * [ + * { "name": "Alice", + * "htmlComment": + * "Is anyone reading this?" + * }, + * { "name": "Bob", + * "htmlComment": "Yes! Am I the only other one?" + * } + * ] + * + * + * + * describe('SCE doc demo', function() { + * it('should sanitize untrusted values', function() { + * expect(element.all(by.css('.htmlComment')).first().getAttribute('innerHTML')) + * .toBe('Is anyone reading this?'); + * }); + * + * it('should NOT sanitize explicitly trusted values', function() { + * expect(element(by.id('explicitlyTrustedHtml')).getAttribute('innerHTML')).toBe( + * 'Hover over this text.'); + * }); + * }); + * + * + * + * + * + * ## Can I disable SCE completely? + * + * Yes, you can. However, this is strongly discouraged. SCE gives you a lot of security benefits + * for little coding overhead. It will be much harder to take an SCE disabled application and + * either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE + * for cases where you have a lot of existing code that was written before SCE was introduced and + * you're migrating them a module at a time. Also do note that this is an app-wide setting, so if + * you are writing a library, you will cause security bugs applications using it. + * + * That said, here's how you can completely disable SCE: + * + * ``` + * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) { + * // Completely disable SCE.

Its goal is to assist in writing code in a way that (a) is secure by default, and - * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier. - * - * ### Overview - * - * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in - * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically - * run security checks on them (sanitizations, whitelists, depending on context), or throw when it - * cannot guarantee the security of the result. That behavior depends strongly on contexts: HTML - * can be sanitized, but template URLs cannot, for instance. - * - * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML: - * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it - * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and - * render the input as-is, you will need to mark it as trusted for that context before attempting - * to bind it. - * - * As of version 1.2, AngularJS ships with SCE enabled by default. - * - * ### In practice - * - * Here's an example of a binding in a privileged context: - * - * ``` - * - * - * ``` - * - * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE - * disabled, this application allows the user to render arbitrary HTML into the DIV, which would - * be an XSS security bug. In a more realistic example, one may be rendering user comments, blog - * articles, etc. via bindings. (HTML is just one example of a context where rendering user - * controlled input creates security vulnerabilities.) - * - * For the case of HTML, you might use a library, either on the client side, or on the server side, - * to sanitize unsafe HTML before binding to the value and rendering it in the document. - * - * How would you ensure that every place that used these types of bindings was bound to a value that - * was sanitized by your library (or returned as safe for rendering by your server?) How can you - * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some - * properties/fields and forgot to update the binding to the sanitized value? - * - * To be secure by default, AngularJS makes sure bindings go through that sanitization, or - * any similar validation process, unless there's a good reason to trust the given value in this - * context. That trust is formalized with a function call. This means that as a developer, you - * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues, - * you just need to ensure the values you mark as trusted indeed are safe - because they were - * received from your server, sanitized by your library, etc. You can organize your codebase to - * help with this - perhaps allowing only the files in a specific directory to do this. - * Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then - * becomes a more manageable task. - * - * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs} - * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to - * build the trusted versions of your values. - * - * ### How does it work? - * - * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted - * $sce.getTrusted(context, value)} rather than to the value directly. Think of this function as - * a way to enforce the required security context in your data sink. Directives use {@link - * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs - * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also, - * when binding without directives, AngularJS will understand the context of your bindings - * automatically. - * - * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link - * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly - * simplified): - * - * ``` - * var ngBindHtmlDirective = ['$sce', function($sce) { - * return function(scope, element, attr) { - * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) { - * element.html(value || ''); - * }); - * }; - * }]; - * ``` - * - * ### Impact on loading templates - * - * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as - * `templateUrl`'s specified by {@link guide/directive directives}. - * - * By default, AngularJS only loads templates from the same domain and protocol as the application - * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl - * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or - * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist - * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value. - * - * *Please note*: - * The browser's - * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest) - * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/) - * policy apply in addition to this and may further restrict whether the template is successfully - * loaded. This means that without the right CORS policy, loading templates from a different domain - * won't work on all browsers. Also, loading templates from `file://` URL does not work on some - * browsers. - * - * ### This feels like too much overhead - * - * It's important to remember that SCE only applies to interpolation expressions. - * - * If your expressions are constant literals, they're automatically trusted and you don't need to - * call `$sce.trustAs` on them (e.g. - * ``) just works. The `$sceDelegate` will - * also use the `$sanitize` service if it is available when binding untrusted values to - * `$sce.HTML` context. AngularJS provides an implementation in `angular-sanitize.js`, and if you - * wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in - * your application. - * - * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load - * templates in `ng-include` from your application's domain without having to even know about SCE. - * It blocks loading templates from other domains or loading templates over http from an https - * served document. You can change these by setting your own custom {@link - * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link - * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs. - * - * This significantly reduces the overhead. It is far easier to pay the small overhead and have an - * application that's secure and can be audited to verify that with much more ease than bolting - * security onto an application later. - * - * - * ### What trusted context types are supported? - * - * | Context | Notes | - * |---------------------|----------------| - * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered, and the {@link ngSanitize.$sanitize $sanitize} service is available (implemented by the {@link ngSanitize ngSanitize} module) this will sanitize the value instead of throwing an error. | - * | `$sce.CSS` | For CSS that's safe to source into the application. Currently, no bindings require this context. Feel free to use it in your own directives. | - * | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does (it's not just the URL that matters, but also what is at the end of it), and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. | - * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently, no bindings require this context. Feel free to use it in your own directives. | - * - * - * Be aware that `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them - * through {@link ng.$sce#getTrusted $sce.getTrusted}. There's no CSS-, URL-, or JS-context bindings - * in AngularJS currently, so their corresponding `$sce.trustAs` functions aren't useful yet. This - * might evolve. - * - * ### Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} - * - * Each element in these arrays must be one of the following: - * - * - **'self'** - * - The special **string**, `'self'`, can be used to match against all URLs of the **same - * domain** as the application document using the **same protocol**. - * - **String** (except the special value `'self'`) - * - The string is matched against the full *normalized / absolute URL* of the resource - * being tested (substring matches are not good enough.) - * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters - * match themselves. - * - `*`: matches zero or more occurrences of any character other than one of the following 6 - * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use - * in a whitelist. - * - `**`: matches zero or more occurrences of *any* character. As such, it's not - * appropriate for use in a scheme, domain, etc. as it would match too much. (e.g. - * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might - * not have been the intention.) Its usage at the very end of the path is ok. (e.g. - * http://foo.example.com/templates/**). - * - **RegExp** (*see caveat below*) - * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax - * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to - * accidentally introduce a bug when one updates a complex expression (imho, all regexes should - * have good test coverage). For instance, the use of `.` in the regex is correct only in a - * small number of cases. A `.` character in the regex used when matching the scheme or a - * subdomain could be matched against a `:` or literal `.` that was likely not intended. It - * is highly recommended to use the string patterns and only fall back to regular expressions - * as a last resort. - * - The regular expression must be an instance of RegExp (i.e. not a string.) It is - * matched against the **entire** *normalized / absolute URL* of the resource being tested - * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags - * present on the RegExp (such as multiline, global, ignoreCase) are ignored. - * - If you are generating your JavaScript from some other templating engine (not - * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)), - * remember to escape your regular expression (and be aware that you might need more than - * one level of escaping depending on your templating engine and the way you interpolated - * the value.) Do make use of your platform's escaping mechanism as it might be good - * enough before coding your own. E.g. Ruby has - * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape) - * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape). - * Javascript lacks a similar built in function for escaping. Take a look at Google - * Closure library's [goog.string.regExpEscape(s)]( - * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962). - * - * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example. - * - * ### Show me an example using SCE. - * - * - * - * - * - * User comments - * By default, HTML that isn't explicitly trusted (e.g. Alice's comment) is sanitized when - * $sanitize is available.

Nested forms can be useful, for example, if the validity of a sub-group - * of controls needs to be determined. - * - * ## CSS classes - * - `ng-valid` is set if the form is valid. - * - `ng-invalid` is set if the form is invalid. - * - `ng-pending` is set if the form is pending. - * - `ng-pristine` is set if the form is pristine. - * - `ng-dirty` is set if the form is dirty. - * - `ng-submitted` is set if the form was submitted. - * - * Keep in mind that ngAnimate can detect each of these classes when added and removed. - * - * - * ## Submitting a form and preventing the default action - * - * Since the role of forms in client-side AngularJS applications is different than in classical - * roundtrip apps, it is desirable for the browser not to translate the form submission into a full - * page reload that sends the data to the server. Instead some javascript logic should be triggered - * to handle the form submission in an application-specific way. - * - * For this reason, AngularJS prevents the default action (form submission to the server) unless the - * `` element has an `action` attribute specified. - * - * You can use one of the following two ways to specify what javascript method should be called when - * a form is submitted: - * - * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element - * - {@link ng.directive:ngClick ngClick} directive on the first - * button or input field of type submit (input[type=submit]) - * - * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit} - * or {@link ng.directive:ngClick ngClick} directives. - * This is because of the following form submission rules in the HTML specification: - * - * - If a form has only one input field then hitting enter in this field triggers form submit - * (`ngSubmit`) - * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter - * doesn't trigger submit - * - if a form has one or more input fields and one or more buttons or input[type=submit] then - * hitting enter in any of the input fields will trigger the click handler on the *first* button or - * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`) - * - * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is - * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit` - * to have access to the updated model. - * - * @animations - * Animations in ngForm are triggered when any of the associated CSS classes are added and removed. - * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any - * other validations that are performed within the form. Animations in ngForm are similar to how - * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well - * as JS animations. - * - * The following example shows a simple way to utilize CSS transitions to style a form element - * that has been rendered as invalid after it has been validated: - * - * - * //be sure to include ngAnimate as a module to hook into more - * //advanced animations - * .my-form { - * transition:0.5s linear all; - * background: white; - * } - * .my-form.ng-invalid { - * background: red; - * color:white; - * } - * - * - * @example - - - - - - userType: - Required! - userType = {{userType}} - myForm.input.$valid = {{myForm.input.$valid}} - myForm.input.$error = {{myForm.input.$error}} - myForm.$valid = {{myForm.$valid}} - myForm.$error.required = {{!!myForm.$error.required}} - - - - it('should initialize to model', function() { + + + userType: + Required! + userType = {{userType}} + myForm.input.$valid = {{myForm.input.$valid}} + myForm.input.$error = {{myForm.input.$error}} + myForm.$valid = {{myForm.$valid}} + myForm.$error.required = {{!!myForm.$error.required}} + + + + it('should initialize to model', function() { var userType = element(by.binding('userType')); var valid = element(by.binding('myForm.input.$valid')); @@ -23778,7 +24969,7 @@ expect(valid.getText()).toContain('true'); }); - it('should be invalid if empty', function() { + it('should be invalid if empty', function() { var userType = element(by.binding('userType')); var valid = element(by.binding('myForm.input.$valid')); var userInput = element(by.model('userType')); @@ -23789,203 +24980,203 @@ expect(userType.getText()).toEqual('userType ='); expect(valid.getText()).toContain('false'); }); - - - * - * @param {string=} name Name of the form.

You can specify an `ngModelOptions` directive on any element. All {@link ngModel} + * directives will use the options of their nearest `ngModelOptions` ancestor. + * + * The `ngModelOptions` settings are found by evaluating the value of the attribute directive as + * an AngularJS expression. This expression should evaluate to an object, whose properties contain + * the settings. For example: ` + * + * + * + * + * ``` + * + * the `input` element will have the following settings + * + * ```js + * { allowInvalid: true, updateOn: 'default', debounce: 0 } + * ``` + * + * Notice that the `debounce` setting was not inherited and used the default value instead. + * + * You can specify that all undefined settings are automatically inherited from an ancestor by + * including a property with key of `"*"` and value of `"$inherit"`. + * + * For example given the following fragment of HTML + * + * + * ```html + * + * + * + * + * + * ``` + * + * the `input` element will have the following settings + * + * ```js + * { allowInvalid: true, updateOn: 'default', debounce: 200 } + * ``` + * + * Notice that the `debounce` setting now inherits the value from the outer `` element. + * + * If you are creating a reusable component then you should be careful when using `"*": "$inherit"` + * since you may inadvertently inherit a setting in the future that changes the behavior of your component. + * + * + * ## Triggering and debouncing model updates + * + * The `updateOn` and `debounce` properties allow you to specify a custom list of events that will + * trigger a model update and/or a debouncing delay so that the actual update only takes place when + * a timer expires; this timer will be reset after another change takes place. + * + * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might + * be different from the value in the actual model. This means that if you update the model you + * should also invoke {@link ngModel.NgModelController#$rollbackViewValue} on the relevant input field in + * order to make sure it is synchronized with the model and that any debounced action is canceled. + * + * The easiest way to reference the control's {@link ngModel.NgModelController#$rollbackViewValue} + * method is by making sure the input is placed inside a form that has a `name` attribute. This is + * important because `form` controllers are published to the related scope under the name in their + * `name` attribute. + * + * Any pending changes will take place immediately when an enclosing form is submitted via the + * `submit` event. Note that `ngClick` events will occur before the model is updated.

Every event that is not listed + * in `updateOn` is considered a "default" event, since different control types have different + * default events. + * + * The control in this example updates by "default", "click", and "blur", with different `debounce` + * values. You can see that "click" doesn't have an individual `debounce` value - + * therefore it uses the `*` debounce value. + * + * There is also a button that calls {@link ngModel.NgModelController#$setViewValue $setViewValue} + * directly with a "custom" event. Since "custom" is not defined in the `updateOn` list, + * it is considered a "default" event and will update the + * control if "default" is defined in `updateOn`, and will receive the "default" debounce value. + * Note that this is just to illustrate how custom controls would possibly call `$setViewValue`. + * + * You can change the `updateOn` and `debounce` configuration to test different scenarios. This + * is done with {@link ngModel.NgModelController#$overrideModelOptions $overrideModelOptions}. + * + + + + + + angular.module('optionsExample', []) + .component('modelUpdateDemo', { + templateUrl: 'template.html', + controller: function() { + this.name = 'Chinua'; + + this.options = { + updateOn: 'default blur click', + debounce: { + default: 2000, + blur: 0, + '*': 1000 + } + }; + this.updateEvents = function() { + var eventList = this.options.updateOn.split(' '); + eventList.push('*'); + var events = {}; - /** - * @ngdoc directive - * @name ngModelOptions - * @restrict A - * @priority 10 - * - * @description - * This directive allows you to modify the behaviour of {@link ngModel} directives within your - * application. You can specify an `ngModelOptions` directive on any element. All {@link ngModel} - * directives will use the options of their nearest `ngModelOptions` ancestor. - * - * The `ngModelOptions` settings are found by evaluating the value of the attribute directive as - * an AngularJS expression. This expression should evaluate to an object, whose properties contain - * the settings. For example: ` - * - * - * - * - * ``` - * - * the `input` element will have the following settings - * - * ```js - * { allowInvalid: true, updateOn: 'default', debounce: 0 } - * ``` - * - * Notice that the `debounce` setting was not inherited and used the default value instead. - * - * You can specify that all undefined settings are automatically inherited from an ancestor by - * including a property with key of `"*"` and value of `"$inherit"`. - * - * For example given the following fragment of HTML - * - * - * ```html - * - * - * - * - * - * ``` - * - * the `input` element will have the following settings - * - * ```js - * { allowInvalid: true, updateOn: 'default', debounce: 200 } - * ``` - * - * Notice that the `debounce` setting now inherits the value from the outer `` element. - * - * If you are creating a reusable component then you should be careful when using `"*": "$inherit"` - * since you may inadvertently inherit a setting in the future that changes the behavior of your component. - * - * - * ## Triggering and debouncing model updates - * - * The `updateOn` and `debounce` properties allow you to specify a custom list of events that will - * trigger a model update and/or a debouncing delay so that the actual update only takes place when - * a timer expires; this timer will be reset after another change takes place. - * - * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might - * be different from the value in the actual model. This means that if you update the model you - * should also invoke {@link ngModel.NgModelController#$rollbackViewValue} on the relevant input field in - * order to make sure it is synchronized with the model and that any debounced action is canceled. - * - * The easiest way to reference the control's {@link ngModel.NgModelController#$rollbackViewValue} - * method is by making sure the input is placed inside a form that has a `name` attribute. This is - * important because `form` controllers are published to the related scope under the name in their - * `name` attribute. - * - * Any pending changes will take place immediately when an enclosing form is submitted via the - * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit` - * to have access to the updated model. - * - * ### Overriding immediate updates - * - * The following example shows how to override immediate updates.

However, `ngOptions` provides some benefits: - * - more flexibility in how the ``'s model is assigned via the `select` **`as`** part of the - * comprehension expression - * - reduced memory consumption by not creating a new scope for each repeated instance - * - increased render speed by creating the options in a documentFragment instead of individually - * - * When an item in the `` menu is selected, the array element or object property - * represented by the selected option will be bound to the model identified by the `ngModel` - * directive. - * - * Optionally, a single hard-coded `` element, with the value set to an empty string, can - * be nested into the `` element. This element will then represent the `null` or "not selected" - * option. See example below for demonstration. - * - * ## Complex Models (objects or collections) - * - * By default, `ngModel` watches the model by reference, not value. This is important to know when - * binding the select to a model that is an object or a collection. - * - * One issue occurs if you want to preselect an option. For example, if you set - * the model to an object that is equal to an object in your collection, `ngOptions` won't be able to set the selection, - * because the objects are not identical. So by default, you should always reference the item in your collection - * for preselections, e.g.: `$scope.selected = $scope.collection[3]`. - * - * Another solution is to use a `track by` clause, because then `ngOptions` will track the identity - * of the item not by reference, but by the result of the `track by` expression. For example, if your - * collection items have an id property, you would `track by item.id`. - * - * A different issue with objects or collections is that ngModel won't detect if an object property or - * a collection item changes. For that reason, `ngOptions` additionally watches the model using - * `$watchCollection`, when the expression contains a `track by` clause or the the select has the `multiple` attribute. - * This allows ngOptions to trigger a re-rendering of the options even if the actual object/collection - * has not changed identity, but only a property on the object or an item in the collection changes. - * - * Note that `$watchCollection` does a shallow comparison of the properties of the object (or the items in the collection - * if the model is an array). This means that changing a property deeper than the first level inside the - * object/collection will not trigger a re-rendering. - * - * ## `select` **`as`** - * - * Using `select` **`as`** will bind the result of the `select` expression to the model, but - * the value of the `` and `` html elements will be either the index (for array data sources) - * or property name (for object data sources) of the value within the collection. If a **`track by`** expression - * is used, the result of that expression will be set as the value of the `option` and `select` elements. - * - * - * ### `select` **`as`** and **`track by`** - * - * - * Be careful when using `select` **`as`** and **`track by`** in the same expression. - * - * - * Given this array of items on the $scope: - * - * ```js - * $scope.items = [{ - * id: 1, - * label: 'aLabel', - * subItem: { name: 'aSubItem' } - * }, { - * id: 2, - * label: 'bLabel', - * subItem: { name: 'bSubItem' } - * }]; - * ``` - * - * This will work: - * - * ```html - * - * ``` - * ```js - * $scope.selected = $scope.items[0]; - * ``` - * - * but this will not work: - * - * ```html - * - * ``` - * ```js - * $scope.selected = $scope.items[0].subItem; - * ``` - * - * In both examples, the **`track by`** expression is applied successfully to each `item` in the - * `items` array. Because the selected option has been set programmatically in the controller, the - * **`track by`** expression is also applied to the `ngModel` value. In the first example, the - * `ngModel` value is `items[0]` and the **`track by`** expression evaluates to `items[0].id` with - * no issue. In the second example, the `ngModel` value is `items[0].subItem` and the **`track by`** - * expression evaluates to `items[0].subItem.id` (which is undefined).

You configure ngPluralize directive - * by specifying the mappings between - * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html) - * and the strings to be displayed. - * - * ## Plural categories and explicit number rules - * There are two - * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html) - * in AngularJS's default en-US locale: "one" and "other". - * - * While a plural category may match many numbers (for example, in en-US locale, "other" can match - * any number that is not 1), an explicit number rule can only match one number. For example, the - * explicit number rule for "3" matches the number 3. There are examples of plural categories - * and explicit number rules throughout the rest of this documentation. - * - * ## Configuring ngPluralize - * You configure ngPluralize by providing 2 attributes: `count` and `when`. - * You can also provide an optional attribute, `offset`. - * - * The value of the `count` attribute can be either a string or an {@link guide/expression - * AngularJS expression}; these are evaluated on the current scope for its bound value. - * - * The `when` attribute specifies the mappings between plural categories and the actual - * string to be displayed. The value of the attribute should be a JSON object. - * - * The following example shows how to configure ngPluralize: - * - * ```html - * - * - *``` - * - * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not - * specify this rule, 0 would be matched to the "other" category and "0 people are viewing" - * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for - * other numbers, for example 12, so that instead of showing "12 people are viewing", you can - * show "a dozen people are viewing". - * - * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted - * into pluralized strings. In the previous example, AngularJS will replace `{}` with - * `{{personCount}}`. The closed braces `{}` is a placeholder - * for {{numberExpression}}. - * - * If no rule is defined for a category, then an empty string is displayed and a warning is generated. - * Note that some locales define more categories than `one` and `other`. For example, fr-fr defines `few` and `many`. - * - * ## Configuring ngPluralize with offset - * The `offset` attribute allows further customization of pluralized text, which can result in - * a better user experience. For example, instead of the message "4 people are viewing this document", - * you might display "John, Kate and 2 others are viewing this document". - * The offset attribute allows you to offset a number by any desired value. - * Let's take a look at an example: - * - * ```html - * - * - * ``` - * - * Notice that we are still using two plural categories(one, other), but we added - * three explicit number rules 0, 1 and 2. - * When one person, perhaps John, views the document, "John is viewing" will be shown. - * When three people view the document, no explicit number rule is found, so - * an offset of 2 is taken off 3, and AngularJS uses 1 to decide the plural category. - * In this case, plural category 'one' is matched and "John, Mary and one other person are viewing" - * is shown. - * - * Note that when you specify offsets, you must provide explicit number rules for - * numbers from 0 up to and including the offset. If you use an offset of 3, for example, - * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for - * plural categories "one" and "other". - * - * @param {string|expression} count The variable to be bound to. - * @param {string} when The mapping between plural category to its corresponding strings. - * @param {number=} offset Offset to deduct from the total number. - * - * @example - - - - - Person 1: - Person 2: - Number of People: - - - Without Offset: - + Person 1: + Person 2: + Number of People: + + + Without Offset: + - + - - With Offset(2): - - - - - - it('should show correct pluralized string', function() { + + + + + it('should show correct pluralized string', function() { var withoutOffset = element.all(by.css('ng-pluralize')).get(0); var withOffset = element.all(by.css('ng-pluralize')).get(1); var countInput = element(by.model('personCount')); @@ -31218,7 +32899,7 @@ expect(withoutOffset.getText()).toEqual('4 people are viewing.'); expect(withOffset.getText()).toEqual('Igor, Misko and 2 other people are viewing.'); }); - it('should show data-bound names', function() { + it('should show data-bound names', function() { var withOffset = element.all(by.css('ng-pluralize')).get(1); var personCount = element(by.model('personCount')); var person1 = element(by.model('person1')); @@ -31231,178 +32912,473 @@ person2.sendKeys('Vojta'); expect(withOffset.getText()).toEqual('Di, Vojta and 2 other people are viewing.'); }); - - - */ - var ngPluralizeDirective = ['$locale', '$interpolate', '$log', function($locale, $interpolate, $log) { - var BRACE = /{}/g, - IS_WHEN = /^when(Minus)?(.+)$/; + + + */ +var ngPluralizeDirective = ['$locale', '$interpolate', '$log', function($locale, $interpolate, $log) { + var BRACE = /{}/g, + IS_WHEN = /^when(Minus)?(.+)$/; + + return { + link: function(scope, element, attr) { + var numberExp = attr.count, + whenExp = attr.$attr.when && element.attr(attr.$attr.when), // we have {{}} in attrs + offset = attr.offset || 0, + whens = scope.$eval(whenExp) || {}, + whensExpFns = {}, + startSymbol = $interpolate.startSymbol(), + endSymbol = $interpolate.endSymbol(), + braceReplacement = startSymbol + numberExp + '-' + offset + endSymbol, + watchRemover = angular.noop, + lastCount; + + forEach(attr, function(expression, attributeName) { + var tmpMatch = IS_WHEN.exec(attributeName); + if (tmpMatch) { + var whenKey = (tmpMatch[1] ?

Each template - * instance gets its own scope, where the given loop variable is set to the current collection item, - * and `$index` is set to the item index or key. - * - * Special properties are exposed on the local scope of each template instance, including: - * - * | Variable | Type | Details | - * |-----------|-----------------|-----------------------------------------------------------------------------| - * | `$index` | {@type number} | iterator offset of the repeated element (0..length-1) | - * | `$first` | {@type boolean} | true if the repeated element is first in the iterator. | - * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. | - * | `$last` | {@type boolean} | true if the repeated element is last in the iterator. | - * | `$even` | {@type boolean} | true if the iterator position `$index` is even (otherwise false). | - * | `$odd` | {@type boolean} | true if the iterator position `$index` is odd (otherwise false). | - * - * - * Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}. - * This may be useful when, for instance, nesting ngRepeats. - * - * - * - * ## Iterating over object properties - * - * It is possible to get `ngRepeat` to iterate over the properties of an object using the following - * syntax: - * - * ```js - * ... - * ``` - * - * However, there are a few limitations compared to array iteration: - * - * - The JavaScript specification does not define the order of keys - * returned for an object, so AngularJS relies on the order returned by the browser - * when running `for key in myObj`. Browsers generally follow the strategy of providing - * keys in the order in which they were defined, although there are exceptions when keys are deleted - * and reinstated. See the - * [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes). - * - * - `ngRepeat` will silently *ignore* object keys starting with `$`, because - * it's a prefix used by AngularJS for public (`$`) and private (`$$`) properties. - * - * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with - * objects, and will throw an error if used with one. - * - * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array - * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could - * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter) - * or implement a `$watch` on the object yourself. - * - * - * ## Tracking and Duplicates - * - * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in - * the collection.

Each template + * instance gets its own scope, where the given loop variable is set to the current collection item, + * and `$index` is set to the item index or key. + * + * Special properties are exposed on the local scope of each template instance, including: + * + * | Variable | Type | Details | + * |-----------|-----------------|-----------------------------------------------------------------------------| + * | `$index` | {@type number} | iterator offset of the repeated element (0..length-1) | + * | `$first` | {@type boolean} | true if the repeated element is first in the iterator. | + * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. | + * | `$last` | {@type boolean} | true if the repeated element is last in the iterator. | + * | `$even` | {@type boolean} | true if the iterator position `$index` is even (otherwise false). | + * | `$odd` | {@type boolean} | true if the iterator position `$index` is odd (otherwise false). | + * + * + * Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}. + * This may be useful when, for instance, nesting ngRepeats. + * + * + * + * ## Iterating over object properties + * + * It is possible to get `ngRepeat` to iterate over the properties of an object using the following + * syntax: + * + * ```js + * ... + * ``` + * + * However, there are a few limitations compared to array iteration: + * + * - The JavaScript specification does not define the order of keys + * returned for an object, so AngularJS relies on the order returned by the browser + * when running `for key in myObj`. Browsers generally follow the strategy of providing + * keys in the order in which they were defined, although there are exceptions when keys are deleted + * and reinstated. See the + * [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes). + * + * - `ngRepeat` will silently *ignore* object keys starting with `$`, because + * it's a prefix used by AngularJS for public (`$`) and private (`$$`) properties. + * + * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with + * objects, and will throw an error if used with one. + * + * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array + * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could + * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter) + * or implement a `$watch` on the object yourself. + * + * + * ## Tracking and Duplicates + * + * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in + * the collection. When a change happens, `ngRepeat` then makes the corresponding changes to the DOM: + * + * * When an item is added, a new instance of the template is added to the DOM. + * * When an item is removed, its template instance is removed from the DOM. + * * When items are reordered, their respective templates are reordered in the DOM. + * + * To minimize creation of DOM elements, `ngRepeat` uses a function + * to "keep track" of all items in the collection and their corresponding DOM elements. + * For example, if an item is added to the collection, `ngRepeat` will know that all other items + * already have DOM elements, and will not re-render them. + * + * All different types of tracking functions, their syntax, and their support for duplicate + * items in collections can be found in the + * {@link ngRepeat#ngRepeat-arguments ngRepeat expression description}. + * + * + * **Best Practice:** If you are working with objects that have a unique identifier property, you + * should track by this identifier instead of the object instance, + * e.g. `item in items track by item.id`. + * Should you reload your data later, `ngRepeat` will not have to rebuild the DOM elements for items + * it has already rendered, even if the JavaScript objects in the collection have been substituted + * for new ones.

For CSP mode please add `angular-csp.css` to your HTML file (see + * {@link ng.directive:ngCsp ngCsp}). + * + * ```html + * + * + * + * + * + * ``` + * + * When the `ngHide` expression evaluates to a truthy value then the `.ng-hide` CSS class is added + * to the class attribute on the element causing it to become hidden. When falsy, the `.ng-hide` + * CSS class is removed from the element causing the element not to appear hidden. + * + * ## Why is `!important` used? + * + * You may be wondering why `!important` is used for the `.ng-hide` CSS class. This is because the + * `.ng-hide` selector can be easily overridden by heavier selectors. For example, something as + * simple as changing the display style on a HTML list item would make hidden elements appear + * visible. This also becomes a bigger issue when dealing with CSS frameworks. + * + * By using `!important`, the show and hide behavior will work as expected despite any clash between + * CSS selector specificity (when `!important` isn't used with any conflicting styles). If a + * developer chooses to override the styling to change how to hide an element then it is just a + * matter of using `!important` in their own CSS code. + * + * ### Overriding `.ng-hide` + * + * By default, the `.ng-hide` class will style the element with `display: none !important`. If you + * wish to change the hide behavior with `ngShow`/`ngHide`, you can simply overwrite the styles for + * the `.ng-hide` CSS class. Note that the selector that needs to be used is actually + * `.ng-hide:not(.ng-hide-animate)` to cope with extra animation classes that can be added. + * + * ```css + * .ng-hide:not(.ng-hide-animate) { + * /* These are just alternative ways of hiding an element */ + * display: block!important; + * position: absolute; + * top: -9999px; + * left: -9999px; + * } + * ``` + * + * By default you don't need to override in CSS anything and the animations will work around the + * display style. + * + * @animations + * | Animation | Occurs | + * |-----------------------------------------------------|------------------------------------------------------------------------------------------------------------| + * | {@link $animate#addClass addClass} `.ng-hide` | After the `ngHide` expression evaluates to a truthy value and just before the contents are set to hidden. | + * | {@link $animate#removeClass removeClass} `.ng-hide` | After the `ngHide` expression evaluates to a non truthy value and just before contents are set to visible. | + * + * Animations in `ngShow`/`ngHide` work with the show and hide events that are triggered when the + * directive expression is true and false.

Its goal is to assist in writing code in a way that (a) is secure by default, and + * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier. + * + * ### Overview + * + * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in + * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically + * run security checks on them (sanitizations, whitelists, depending on context), or throw when it + * cannot guarantee the security of the result. That behavior depends strongly on contexts: HTML + * can be sanitized, but template URLs cannot, for instance. + * + * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML: + * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it + * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and + * render the input as-is, you will need to mark it as trusted for that context before attempting + * to bind it. + * + * As of version 1.2, AngularJS ships with SCE enabled by default. + * + * ### In practice + * + * Here's an example of a binding in a privileged context: + * + * ``` + * + * + * ``` + * + * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE + * disabled, this application allows the user to render arbitrary HTML into the DIV, which would + * be an XSS security bug. In a more realistic example, one may be rendering user comments, blog + * articles, etc. via bindings. (HTML is just one example of a context where rendering user + * controlled input creates security vulnerabilities.) + * + * For the case of HTML, you might use a library, either on the client side, or on the server side, + * to sanitize unsafe HTML before binding to the value and rendering it in the document. + * + * How would you ensure that every place that used these types of bindings was bound to a value that + * was sanitized by your library (or returned as safe for rendering by your server?) How can you + * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some + * properties/fields and forgot to update the binding to the sanitized value? + * + * To be secure by default, AngularJS makes sure bindings go through that sanitization, or + * any similar validation process, unless there's a good reason to trust the given value in this + * context. That trust is formalized with a function call. This means that as a developer, you + * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues, + * you just need to ensure the values you mark as trusted indeed are safe - because they were + * received from your server, sanitized by your library, etc. You can organize your codebase to + * help with this - perhaps allowing only the files in a specific directory to do this. + * Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then + * becomes a more manageable task. + * + * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs} + * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to + * build the trusted versions of your values. + * + * ### How does it work? + * + * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted + * $sce.getTrusted(context, value)} rather than to the value directly. Think of this function as + * a way to enforce the required security context in your data sink. Directives use {@link + * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs + * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also, + * when binding without directives, AngularJS will understand the context of your bindings + * automatically. + * + * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link + * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly + * simplified): + * + * ``` + * var ngBindHtmlDirective = ['$sce', function($sce) { + * return function(scope, element, attr) { + * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) { + * element.html(value || ''); + * }); + * }; + * }]; + * ``` + * + * ### Impact on loading templates + * + * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as + * `templateUrl`'s specified by {@link guide/directive directives}. + * + * By default, AngularJS only loads templates from the same domain and protocol as the application + * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl + * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or + * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist + * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value. + * + * *Please note*: + * The browser's + * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest) + * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/) + * policy apply in addition to this and may further restrict whether the template is successfully + * loaded. This means that without the right CORS policy, loading templates from a different domain + * won't work on all browsers. Also, loading templates from `file://` URL does not work on some + * browsers. + * + * ### This feels like too much overhead + * + * It's important to remember that SCE only applies to interpolation expressions. + * + * If your expressions are constant literals, they're automatically trusted and you don't need to + * call `$sce.trustAs` on them (e.g. + * ``) just works (remember to include the + * `ngSanitize` module). The `$sceDelegate` will also use the `$sanitize` service if it is available + * when binding untrusted values to `$sce.HTML` context. + * AngularJS provides an implementation in `angular-sanitize.js`, and if you + * wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in + * your application. + * + * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load + * templates in `ng-include` from your application's domain without having to even know about SCE. + * It blocks loading templates from other domains or loading templates over http from an https + * served document. You can change these by setting your own custom {@link + * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link + * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs. + * + * This significantly reduces the overhead. It is far easier to pay the small overhead and have an + * application that's secure and can be audited to verify that with much more ease than bolting + * security onto an application later. + * + * + * ### What trusted context types are supported? + * + * | Context | Notes | + * |---------------------|----------------| + * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. | + * | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. | + * | `$sce.MEDIA_URL` | For URLs that are safe to render as media. Is automatically converted from string by sanitizing when needed. | + * | `$sce.URL` | For URLs that are safe to follow as links. Is automatically converted from string by sanitizing when needed. Note that `$sce.URL` makes a stronger statement about the URL than `$sce.MEDIA_URL` does and therefore contexts requiring values trusted for `$sce.URL` can be used anywhere that values trusted for `$sce.MEDIA_URL` are required.| + * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application. Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.) Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` or `$sce.MEDIA_URL` do and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` or `$sce.MEDIA_URL` are required. The {@link $sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider#resourceUrlWhitelist()} and {@link $sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider#resourceUrlBlacklist()} can be used to restrict trusted origins for `RESOURCE_URL` | + * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. | + * + * + * + * Be aware that, before AngularJS 1.7.0, `a[href]` and `img[src]` used to sanitize their + * interpolated values directly rather than rely upon {@link ng.$sce#getTrusted `$sce.getTrusted`}. + * + * **As of 1.7.0, this is no longer the case.** + * + * Now such interpolations are marked as requiring `$sce.URL` (for `a[href]`) or `$sce.MEDIA_URL` + * (for `img[src]`), so that the sanitization happens (via `$sce.getTrusted...`) when the `$interpolate` + * service evaluates the expressions. + * + * + * There are no CSS or JS context bindings in AngularJS currently, so their corresponding `$sce.trustAs` + * functions aren't useful yet. This might evolve. + * + * ### Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} + * + * Each element in these arrays must be one of the following: + * + * - **'self'** + * - The special **string**, `'self'`, can be used to match against all URLs of the **same + * domain** as the application document using the **same protocol**. + * - **String** (except the special value `'self'`) + * - The string is matched against the full *normalized / absolute URL* of the resource + * being tested (substring matches are not good enough.) + * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters + * match themselves. + * - `*`: matches zero or more occurrences of any character other than one of the following 6 + * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use + * in a whitelist. + * - `**`: matches zero or more occurrences of *any* character. As such, it's not + * appropriate for use in a scheme, domain, etc. as it would match too much. (e.g. + * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might + * not have been the intention.) Its usage at the very end of the path is ok. (e.g. + * http://foo.example.com/templates/**). + * - **RegExp** (*see caveat below*) + * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax + * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to + * accidentally introduce a bug when one updates a complex expression (imho, all regexes should + * have good test coverage). For instance, the use of `.` in the regex is correct only in a + * small number of cases. A `.` character in the regex used when matching the scheme or a + * subdomain could be matched against a `:` or literal `.` that was likely not intended. It + * is highly recommended to use the string patterns and only fall back to regular expressions + * as a last resort. + * - The regular expression must be an instance of RegExp (i.e. not a string.) It is + * matched against the **entire** *normalized / absolute URL* of the resource being tested + * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags + * present on the RegExp (such as multiline, global, ignoreCase) are ignored. + * - If you are generating your JavaScript from some other templating engine (not + * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)), + * remember to escape your regular expression (and be aware that you might need more than + * one level of escaping depending on your templating engine and the way you interpolated + * the value.) Do make use of your platform's escaping mechanism as it might be good + * enough before coding your own. E.g. Ruby has + * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape) + * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape). + * Javascript lacks a similar built in function for escaping. Take a look at Google + * Closure library's [goog.string.regExpEscape(s)]( + * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962). + * + * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example. + * + * ### Show me an example using SCE. + * + * + * + * + * + * User comments + * By default, HTML that isn't explicitly trusted (e.g. Alice's comment) is sanitized when + * $sanitize is available.

However, this is strongly discouraged. SCE gives you a lot of security benefits + * for little coding overhead. It will be much harder to take an SCE disabled application and + * either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE + * for cases where you have a lot of existing code that was written before SCE was introduced and + * you're migrating them a module at a time. Also do note that this is an app-wide setting, so if + * you are writing a library, you will cause security bugs applications using it. + * + * That said, here's how you can completely disable SCE: + * + * ``` + * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) { + * // Completely disable SCE.

Its goal is to assist in writing code in a way that (a) is secure by default, and - * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier. - * - * ### Overview - * - * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in - * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically - * run security checks on them (sanitizations, whitelists, depending on context), or throw when it - * cannot guarantee the security of the result. That behavior depends strongly on contexts: HTML - * can be sanitized, but template URLs cannot, for instance. - * - * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML: - * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it - * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and - * render the input as-is, you will need to mark it as trusted for that context before attempting - * to bind it. - * - * As of version 1.2, AngularJS ships with SCE enabled by default. - * - * ### In practice - * - * Here's an example of a binding in a privileged context: - * - * ``` - * - *
