#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 on 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'
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.
You can bind a key sequence to any event type by using an array of key combos in place of a single combo. In this case, it waits for the entire sequence to be entered, in order, before invoking the handler. Here's the syntax:
#(document).bind("keydown", ["a", "b", "c"], function () {
alert("a->b->c!");
});
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.
