This is a clone of medium.com inline editor toolbar.
Since I always had problems with bloated editors and I loved the simplicity of medium.com solution I've tried to implement their WYSIWYG approach with this script.
MediumEditor has been written using vanilla JavaScript, no additional frameworks required.

demo: http://daviferreira.github.io/medium-editor/
First, you need to attach medium editor's stylesheet to your page:
<link rel="stylesheet" href="css/medium-editor.css"> <!-- Core -->
<link rel="stylesheet" href="css/themes/default.css"> <!-- or any other theme -->The next step is to reference the editor's script and instantiate a new MediumEditor object:
<script src="js/medium-editor.js"></script>
<script>var editor = new MediumEditor('.editable');</script>The above code will transform all the elements with the .editable class into HTML5 editable contents and add the medium editor toolbar to them.
You can also pass a list of HTML elements:
var elements = document.querySelectorAll('.editable'),
editor = new MediumEditor(elements);If you want to support IE9, you will need to use a classList pollyfill, like Eli Grey's, available at https://github.com/eligrey/classList.js.
- allowMultiParagraphSelection: enables the toolbar when selecting multiple paragraphs/block elements. Default: true
- cleanPastedHTML: cleans pasted content from different sources, like google docs etc. Default: false

- disablePlaceholders: enables/disables support for placeholder, including DOM element creation and attaching event handlers. When disabled, medium-editor will ignore the placholder option and not show placeholder text. Default: false

- disableToolbar: enables/disables the toolbar, adding only the contenteditable behavior. You can also set specific element behavior by using setting a data-disable-toolbar attribute. Default: false
- firstButtonClass: CSS class added to the first button in the toolbar. Default: 'medium-editor-button-first'
- lastButtonClass: CSS class added to the last button in the toolbar. Default: 'medium-editor-button-last'
- onHideToolbar: optional callback that will be called each time the toolbar is actually hidden for this instance of medium-editor.
- staticToolbar: enable/disable the toolbar always displaying in the same location relative to the medium-editor element. Default: false
- stickyToolbar: enable/disable the toolbar "sticking" to the medium-editor element when the page is being scrolled. Default: false
- updateOnEmptySelection: update the state of the toolbar buttons even when the selection is collapse (there is no selection, just a cursor). Default: false

- checkLinkFormat: enables/disables check for common URL protocols on anchor links. Default: false

Example:
var editor = new MediumEditor('.editable', {
anchorInputPlaceholder: 'Type a link',
buttons: ['bold', 'italic', 'quote'],
diffLeft: 25,
diffTop: 10,
firstHeader: 'h1',
secondHeader: 'h2',
delay: 1000,
targetBlank: true
});Medium Editor, by default, will show only the buttons listed above to avoid a huge toolbar. There are a couple of extra buttons you can use:
- superscript
- subscript
- strikethrough
- unorderedlist
- orderedlist
- pre
- justifyLeft
- justifyFull
- justifyCenter
- justifyRight
- image (this simply converts selected text to an image tag)
- indent (moves the selected text up one level)
- outdent (moves the selected text down one level)
Check out the Wiki page for a list of available themes: https://github.com/daviferreira/medium-editor/wiki/Themes
- .deactivate(): disables the editor
- .activate(): re-activates the editor
- .serialize(): returns a JSON object with elements contents
For observing any changes on contentEditable
$('.editable').on('input', function() {
// Do some work
});This is handy when you need to capture modifications other thats outside of key up's scope like clicking on toolbar buttons.
input is supported by Chrome, Firefox, IE9 and other modern browsers. If you want to read more or support older browsers, check Listening to events of a contenteditable HTML element and Detect changes in the DOM
Patrick Stillhar developed a new and improved way to add buttons to our toolbar. Check it out at: https://stillhart.biz/project/MediumButton/
To add additional functions that are not supported by the native browser API you can write extensions that are then integrated into the toolbar. The Extension API is currently unstable and very minimal.
An extension is an object that has essentially two functions getButton and checkState.
-
getButtonis called when the editor is initialized and should return an element that is integrated into the toolbar. Usually this will be a<button>element like the onces Medium Editor uses. All event handling on this button is entirely up to you so you should either keep a reference or bind your eventhandlers before returning it. You can also return a HTML-String that is then integrated into the toolbar also this is not really useful. -
checkStateis called whenever a user selects some text in the area where the Medium Editor instance is running. It's responsability is to toggle the current state of the button. I.e. marking is a on or off. Again the method on how determine the state is entirely up to you.checkStatewill be called multiple times and will receive a DOMElementas parameter.
Properties
parentadd this property to your extension class constructor and set it totrueto be able to access the Medium Editor instance through thebaseproperty that will be set during the initialization
A simple example the uses rangy and the CSS Class Applier Module to support highlighting of text:
rangy.init();
function Highlighter() {
this.button = document.createElement('button');
this.button.className = 'medium-editor-action';
this.button.textContent = 'H';
this.button.onclick = this.onClick.bind(this);
this.classApplier = rangy.createCssClassApplier("highlight", {
elementTagName: 'mark',
normalize: true
});
}
Highlighter.prototype.onClick = function() {
this.classApplier.toggleSelection();
};
Highlighter.prototype.getButton = function() {
return this.button;
};
Highlighter.prototype.checkState = function (node) {
if(node.tagName == 'MARK') {
this.button.classList.add('medium-editor-button-active');
}
};
var e = new MediumEditor('.editor', {
buttons: ['highlight', 'bold', 'italic', 'underline'],
extensions: {
'highlight': new Highlighter()
}
});A simple example that uses the parent attribute:
function Extension() {
this.parent = true;
this.button = document.createElement('button');
this.button.className = 'medium-editor-action';
this.button.textContent = 'X';
this.button.onclick = this.onClick.bind(this);
}
Extension.prototype.getButton = function() {
return this.button;
};
Extension.prototype.onClick = function() {
alert('This is editor: #' + this.base.id);
};
var one = new MediumEditor('.one', {
buttons: ['extension'],
extensions: {
extension: new Extension()
}
});
var two = new MediumEditor('.two', {
buttons: ['extension'],
extensions: {
extension: new Extension()
}
});Pavel Linkesch has developed a jQuery plugin to upload images & embed content (from Twitter, Youtube, Vimeo, etc.) following Medium.com functionality. Check it out at http://orthes.github.io/medium-editor-insert-plugin/
