onkey

onKey.js

A key event controller w/ hot-keys.

Installation

npm install onKey

In addition jQuery-like selector library is required:

• jQuery 1.4.3+
• Zepto

Usage

// Bind a keydown & keyup event to the window
key.down(function(e) {
    alert("key down!");
});
 
key.up(function(e) {
    alert("key up!")
});
 
// Bind keyup to a specific selector (will also take a DOM or jQuery object)
key('#input').down(function() {
    alert('input keydown');
});
 
// Bind hot-keys
key.down({
    'ctrl+alt+tab': function() {
        console.log('ctr+alt+tab pressed!');
    },
    'cmd+a': function() {
        console.log('cmd & ctrl are normalized so that hot-keys work consistently across operating systems');
    }
});
 
// An Event object is returned whenever key(), key.down() or key.up() is called.
// This object can be turned on and off and more key events can be bound to it.
// This is useful for apps where key events are only relevant in certain views.
var keyEvent = key('#input').down(function() {
    alert('boom!');
});
 
keyEvent.off();
// keyEvent won't fire
 
keyEvent.on();
// keyEvent will fire
 
keyEvent.up({
    'ctrl+a': function() {
        alert('Another binding to the same input!');
    }
});
 
// Chaining
key
    .down(callback)
    .up(callback)
    .on()
    .off()
    .destroy(); //Completely unbinds the key events in an event object

Note: Since version 0.1.0 you can't use - as hotkey separator since it can be used as a valid key combination, such as cmd -. It's recommended to use spaces or +.
