keycharm

Easy and free library for binding keys.

Keycharm is on npm so you can install it with:

npm install keycharm

Example:

var keys = keycharm(options);

keys.bind("a", function () {}, 'keydown'); // key, callback function, 'keydown' or 'keyup'

Available options (all are optional):

{
    container: document.getElementById("element"), // optional div to bind keycharm to. It will NEED a tabindex. When not supplied, this defaults to window.
    preventDefault: true/false // default value: false;
}

Supported keys:

'a'-'z', 'A'-'Z', '0'-'9', 'F1'-'F12', 'space', 'enter', 'ctrl', 'alt', 'tab', 'shift', 
'delete', 'esc', 'backspace', '-','=', '[', ']', 'left', 'up', 'right', 'down', 'pageup', 'pagedown'

numpad: 'num0'-'num9', 'num/', 'num*', 'num-', 'num+', 'num.'

Each initiation of keycharm has its own bindings to the key events.

Available methods:

.bind(key, callback, [type]);               // bind key, type = 'keydown' or 'keyup', default type = keydown.
.unbind(key, [callback], [type]);           // unbind key,  type = 'keydown' or 'keyup', default type = keydown. No callback deletes all bound callbacks from key
.reset();                                   // remove all bound keys
.destroy();                                 // remove all bound keys and the event listeners of keycharm
.getKey(event);                             // get the key label of the event
.bindAll(function, 'keydown' or 'keyup');   // bind all keys to this function, could be used for testing or demos.

Keycharm is Dual-licensed with both the Apache 2.0 license as well as the MIT license. I'll leave it up to the user to pick which one they prefer.
