#About jQuery Hotkeys is a plug-in that lets you easily add and remove handlers for keyboard events anywhere in your code supporting almost any key combination.
This plugin is based off of the plugin by Tzury Bar Yochay: jQuery.hotkeys
The syntax is as follows:
$(expression).bind(types, keys, handler);
$(expression).unbind(types, handler);
$(document).bind('keydown', 'ctrl+a', fn);
// e.g. replace '$' sign with 'EUR'
$('input.foo').bind('keyup', '$', function(){
this.value = this.value.replace('$', 'EUR');
});
Syntax when wanting to use jQuery's on()/off methods:
$(expression).on(types, null, keys, handler);
$(expression).off(types, handler);
$(document).on('keydown', null, 'ctrl+a', fn);
// e.g. replace '$' sign with 'EUR'
$('input.foo').on('keyup', null, '$', function(){
this.value = this.value.replace('$', 'EUR');
});
Supported types are 'keydown', 'keyup' and 'keypress'
Works with jQuery 1.4.2 and newer.
It is known to be working with all the major browsers on all available platforms (Win/Mac/Linux)
- IE 6/7/8+
- FF 1.5/2/3+
- Opera-9+
- Safari-3+
- Chrome-0.2+
Modifiers are not case sensitive (Ctrl == ctrl == cTRL)
If you want to use more than one modifier (e.g. alt+ctrl+z) you should define them by an alphabetical order e.g. alt+ctrl+shift
Hotkeys aren't tracked if you're inside of an input element (unless you explicitly bind the hotkey directly to the input). This helps to avoid conflict with normal user typing.
You can use namespacing by adding a suffix to the event type (e.g. keyup.toggle)
Meta and hyper keys don't register on keyup in any browser tested.
Meta key registers on keydown event.
Hyper key registers on keydown event.
Meta key registers on keydown and keypress events.
Hyper key registers on keydown and keypress events.
Meta key doesn't register at all :(
Hyper key registers on keydown and keypress events.
Bind to keydown event for meta and hyper keys, but meta key does not work in Opera ;)
Firefox is the most liberal one in the manner of letting you capture all short-cuts even those that are built-in in the browser such as Ctrl-t for new tab, or Ctrl-a for selecting all text. You can always bubble them up to the browser by returning true in your handler.
Others, (IE) either let you handle built-in short-cuts, but will add their functionality after your code has executed. Or (Opera/Safari) will not pass those events to the DOM at all.
So, if you bind Ctrl-Q or Alt-F4 and your Safari/Opera window is closed don't be surprised.
