Keyvent.js

Keyboard events simulator.

Examples

Simulate 'keydown' events on the 'document' element:

keyvent.down(13); // You can use key codes...
keyvent.down('enter'); // ... a few alias...
keyvent.down('shift a'); // ... combination of keys...
keyvent.down('⇧ a'); // ... and some sugar!

The same is valid for simulating 'keyup' events:

keyvent.up(13);
keyvent.up('enter');
keyvent.up('shift a');
keyvent.up('⇧ a');

If you want to simulate keyboard events on other DOM elements, you have to set a new context (please note that the 'on' function takes a raw DOM element as parameter):

var headerDiv = document.getElementById('headerDiv');
keyvent.on(headerDiv).down('control');

You may want to keep a copy of this context to use later:

var headerDivKeyboard = keyvent.on(headerDiv);
(...)
headerDivKeyboard.up('space');

The following aliases are supported (borrowed from https://github.com/madrobby/keymaster): ⇧, shift, option, ⌥, alt, ctrl, control, command, ⌘, backspace, tab, clear, enter, return, esc, escape, space, up, down, left, right, home, end, pageup, pagedown, del, delete, and f1 through f19.

Notes

The initial intent of this lib is to support testing, but you can find a better usage for it. :-)
If you are using AMD (e.g. require.js) this lib becomes a module. Otherwise it'll create a global keyvent.

Browser Compatibility

I've ran the tests in Chrome and Firefox. If you find any incompatibility or want to support other browsers, please do a pull request with the fix! :-)
