2 * Facebox (for jQuery)
3 * version: 1.2 (05/05/2008)
4 * @requires jQuery v1.2 or later
5 *
6 * Examples at http://famspam.com/facebox/
7 *
8 * Licensed under the MIT:
9 *   http://www.opensource.org/licenses/mit-license.php
10 *
11 * Copyright 2007, 2008 Chris Wanstrath [ [email protected] ]
12 *
13 * Usage:
14 *
15 *  jQuery(document).ready(function() {
16 *    jQuery('a[rel*=facebox]').facebox()
17 *  })
18 *
19 *  <a href="#terms" rel="facebox">Terms</a>
20 *    Loads the #terms div in the box
21 *
22 *  <a href="terms.html" rel="facebox">Terms</a>
23 *    Loads the terms.html page in the box
24 *
25 *  <a href="terms.png" rel="facebox">Terms</a>
26 *    Loads the terms.png image in the box
27 *
28 *
29 *  You can also use it programmatically:
30 *
31 *    jQuery.facebox('some html')
32 *    jQuery.facebox('some html', 'my-groovy-style')
33 *
34 *  The above will open a facebox with "some html" as the content.
35 *
36 *    jQuery.facebox(function($) {
37 *      $.get('blah.html', function(data) { $.facebox(data) })
38 *    })
39 *
40 *  The above will show a loading screen before the passed function is called,
41 *  allowing for a better ajaxy experience.
42 *
43 *  The facebox function can also display an ajax page, an image, or the contents of a div:
44 *
45 *    jQuery.facebox({ ajax: 'remote.html' })
46 *    jQuery.facebox({ ajax: 'remote.html' }, 'my-groovy-style')
47 *    jQuery.facebox({ image: 'stairs.jpg' })
48 *    jQuery.facebox({ image: 'stairs.jpg' }, 'my-groovy-style')
49 *    jQuery.facebox({ div: '#box' })
50 *    jQuery.facebox({ div: '#box' }, 'my-groovy-style')
51 *
52 *  Want to close the facebox?  Trigger the 'close.facebox' document event:
53 *
54 *    jQuery(document).trigger('close.facebox')
55 *
56 *  Facebox also has a bunch of other hooks:
57 *
58 *    loading.facebox
59 *    beforeReveal.facebox
60 *    reveal.facebox (aliased as 'afterReveal.facebox')
61 *    init.facebox
62 *    afterClose.facebox
63 *
64 *  Simply bind a function to any of these hooks:
65 *
66 *   $(document).bind('reveal.facebox', function() { ...stuff to do after the facebox and contents are revealed... })
67 *
