# Mousetrap
|
||||
|
||||
Mousetrap is a simple library for handling keyboard shortcuts in Javascript.
|
||||
|
||||
It is around **1.9kb** minified and gzipped and **3.5kb** minified, has no external dependencies, and has been tested in the following browsers:
|
||||
|
||||
- Internet Explorer 6+
|
||||
- Safari
|
||||
- Firefox
|
||||
- Chrome
|
||||
|
||||
It has support for ``keypress``, ``keydown``, and ``keyup`` events on specific keys, keyboard combinations, or key sequences.
|
||||
|
||||
If you would like to donate to help support Mousetrap development use [Gittip](https://www.gittip.com/ccampbell).
|
||||
|
||||
## Getting started
|
||||
|
||||
1. Include mousetrap on your page before the closing ``</body>`` tag
|
||||
|
||||
```html
|
||||
<script src="/path/to/mousetrap.min.js"></script>
|
||||
```
|
||||
|
||||
2. Add some keyboard events to listen for
|
||||
|
||||
```html
|
||||
<script>
|
||||
// single keys
|
||||
Mousetrap.bind('4', function() { console.log('4'); });
|
||||
Mousetrap.bind("?", function() { console.log('show shortcuts!'); });
|
||||
Mousetrap.bind('esc', function() { console.log('escape'); }, 'keyup');
|
||||
|
||||
// combinations
|
||||
Mousetrap.bind('command+shift+K', function() { console.log('command shift k'); });
|
||||
|
||||
// map multiple combinations to the same callback
|
||||
Mousetrap.bind(['command+k', 'ctrl+k'], function() {
|
||||
console.log('command k or control k');
|
||||
|
||||
// return false to prevent default browser behavior
|
||||
// and stop event from bubbling
|
||||
return false;
|
||||
});
|
||||
|
||||
// gmail style sequences
|
||||
Mousetrap.bind('g i', function() { console.log('go to inbox'); });
|
||||
Mousetrap.bind('* a', function() { console.log('select all'); });
|
||||
|
||||
// konami code!
|
||||
Mousetrap.bind('up up down down left right left right b a enter', function() {
|
||||
console.log('konami code');
|
||||
});
|
||||
</script>
|
||||
```
|
||||
|
||||
## Why Mousetrap?
|
||||
|
||||
There are a number of other similar libraries out there so what makes this one different?
|
||||
|
||||
- There are no external dependencies, no framework is required
|
||||
- You are not limited to ``keydown`` events (You can specify ``keypress``, ``keydown``, or ``keyup`` or let Mousetrap choose for you).
|
||||
- You can bind key events directly to special keys such as ``?`` or ``*`` without having to specify ``shift+/`` or ``shift+8`` which are not consistent across all keyboards
|
||||
- It works with international keyboard layouts
|
||||
- You can bind Gmail like key sequences in addition to regular keys and key combinations
|
||||
- You can programatically trigger key events with the ``trigger()`` method
|
||||
- It works with the numeric keypad on your keyboard
|
||||
- The code is well documented/commented
|
||||
|
||||
