#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](http://github.com/tzuryby/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');
|
||
|
|
});
|
||
|
|
|
||
|
|
## Types
|
||
|
|
Supported types are `'keydown'`, `'keyup'` and `'keypress'`
|
||
|
|
|
||
|
|
## Notes
|
||
|
|
|
||
|
|
If you want to use more than one modifiers (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.
|
||
|
|
|
||
|
|
## jQuery Compatibility
|
||
|
|
|
||
|
|
Works with jQuery 1.4.2 and newer.
|
||
|
|
|
||
|
|
It 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
|
||
|
|
|

|
### Addendum
|
||
|
|
|
||
|
|
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.*
