#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');
});
Supported types are 'keydown'
, 'keyup'
and 'keypress'
Handlers can be bound to a keypresses that contain a definable sequence of characters. For instance, pressing the g
then a
keys. The keypresses in the sequence must be executed within one second of each other to trigger the handler. Any number of characters can be required of a sequence and multiple sequences (seperated by a space) can be bound to the same handler.
jQuery(document).bind('keydown', 'g;a', function (evt)
{
alert('g then a');
});
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.
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
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.
