jQuery.Hotkeys 
#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');
});
Example
Event Types
Supported types are 'keydown', 'keyup' and 'keypress'
jQuery Compatibility
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+
Browserify Compatibility
If you want to include this module in a Browserified project, just add it to node_modules and require it.
require('jquery.javascript');
This will work if jQuery is global (ex. served from a CDN). If it's not, you need to shim it:
{
"browserify-shim": {
"jquery": "global:jQuery"
}
}
Notes
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)
Hotkeys within inputs
Hotkeys aren't tracked if the user is focused within an input element or any element that has contenteditable="true" unless you bind the hotkey directly to the element. This helps to avoid conflict with normal user typing. If you don't want this, you can change the booleans of the following to suit:
jQuery.hotkeys.options.filterInputAcceptingElementsjQuery.hotkeys.options.filterContentEditablejQuery.hotkeys.options.filterTextInputs(deprecated, will be removed in a later version)
Meta and Hyper Keys
Meta and hyper keys don't register on keyup in any browser tested.
Chrome 33.0.1750.117
Meta key registers on keydown event. Hyper key registers on keydown event.
Firefox 27.0.1 and Safari 7.0.1
Meta key registers on keydown and keypress events. Hyper key registers on keydown and keypress events.
Opera 19.0
Meta key doesn't register at all :( Hyper key registers on keydown and keypress events.
TL;DR
Bind to keydown event for meta and hyper keys, but meta key does not work in Opera ;)
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.
