 * Facebox (for jQuery)


 * version: 1.2 (05/05/2008)


 * @requires jQuery v1.2 or later


 *


 * Examples at http://famspam.com/facebox/


 *


 * Licensed under the MIT:


 *   http://www.opensource.org/licenses/mit-license.php


 *


 * Copyright 2007, 2008 Chris Wanstrath [ chris@ozmm.org ]


 *


 * Usage:


 *  


 *  jQuery(document).ready(function() {


 *    jQuery('a[rel*=facebox]').facebox() 


 *  })


 *


 *  <a href="#terms" rel="facebox">Terms</a>


 *    Loads the #terms div in the box


 *


 *  <a href="terms.html" rel="facebox">Terms</a>


 *    Loads the terms.html page in the box


 *


 *  <a href="terms.png" rel="facebox">Terms</a>


 *    Loads the terms.png image in the box


 *


 *


 *  You can also use it programmatically:


 * 


 *    jQuery.facebox('some html')


 *


 *  The above will open a facebox with "some html" as the content.


 *    


 *    jQuery.facebox(function($) { 


 *      $.get('blah.html', function(data) { $.facebox(data) })


 *    })


 *


 *  The above will show a loading screen before the passed function is called,


 *  allowing for a better ajaxy experience.


 *


 *  The facebox function can also display an ajax page or image:


 *  


 *    jQuery.facebox({ ajax: 'remote.html' })


 *    jQuery.facebox({ image: 'dude.jpg' })


 *


 *  Want to close the facebox?  Trigger the 'close.facebox' document event:


 *


 *    jQuery(document).trigger('close.facebox')


 *


 *  Facebox also has a bunch of other hooks:


 *


 *    loading.facebox


 *    beforeReveal.facebox


 *    reveal.facebox (aliased as 'afterReveal.facebox')


 *    init.facebox


 *


 *  Simply bind a function to any of these hooks:


 *


 *   $(document).bind('reveal.facebox', function() { ...stuff to do after the facebox and contents are revealed... })


 *
