 * Facebox (for jQuery)
 * version: 1.2 (05/05/2008)
 * @requires jQuery v1.2 or later
 *
 * Examples at http://famspam.com/js/facebox/
 *
 * Licensed under the MIT:

 *
 * 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' })
 *	  jQuery.facebox({ ajax: 'remote.html' }, 'my-groovy-style')
 *    jQuery.facebox({ image: 'stairs.jpg' })
 *    jQuery.facebox({ image: 'stairs.jpg' }, 'my-groovy-style')
 *    jQuery.facebox({ iframe: 'remote.html })
 *    jQuery.facebox({ iframe: 'remote.html }, 'my-groovy-style')
 *    jQuery.facebox({ div: '#box' })
 *    jQuery.facebox({ div: '#box' }, 'my-groovy-style')
 *
 *  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... })
 *

 /*
 he horizontal position of the DIV would be calculated as:-<br>
<br>
var hPos = Math.round(horizontalScroll+((viewPortWidth-divWidth)/2));<br>
<br>
And vertical as:-<br>
<br>
var vPos = Math.round(verticalScroll+((viewPortHeight-divHeight)/2));<br>
<br>
- but either value may come out less than zero in which case it should<br>
probably be defaulted to zero:-<br>
<br>
hPos = (hPos &lt; 0)?0:hPos;<br>
vPos = (vPos &lt; 0)?0:vPos;<br>
<br>
The next problem is getting a reference to the DIV and more specifically<br>
the - style - object associated with that DIV (or the DIV itself is it<br>
has no style objet. i.e. Netscape 4). Assuming that the DIV is an<br>
absolutely positioned element and that it has an ID attribute a function<br>
such as:-<br>
<br>
function getStyleObj(id){<br>
var obj = null;<br>
if(document.getElementById){<br>
obj = document.getElementById(id);<br>
}else if(document.all){<br>
obj = document.all[id];<br>
}else if(document.layers){<br>
obj = document.layers[id];<br>
}<br>
return (obj &amp;&amp; obj.style) || obj;<br>
}<br>
<br>
- can be used. Called as:-<br>
<br>
var divStyleRef = getStyleObj("divId");<br>
<br>
It is always worth testing the object returned from such a function call<br>
to ensure that it actually refers to an object (else the subsequent code<br>
would produce errors):-<br>
<br>
if(divStyleRef){<br>
. . . // The rest of the code that attempts<br>
// to alter/use divStyleRef.<br>
}<br>
<br>
The position of the DIV can be set by assigning values to its - top -<br>
and - left - properties. However, there is a problem when doing this in<br>
that some browsers require the properties to be numeric values while<br>
others are expecting strings. Not a problem in itself as browsers will<br>
type-convert the assigned value to a type appropriate to the property.<br>
The problem is with the newer browsers operating in " CSS1Compat" (or<br>
"standards") mode, as in the CSS standard property values are _required_<br>
to specify a unit, in our case "px". Fortunately the browsers that<br>
require the CSS units when in standards mode are quite happy to accept<br>
the units when in any mode so we just decide to provide the units if<br>
there is an indication that the browser may care. Obviously appending<br>
"px" to the position value means that the browser will be expecting a<br>
string so the test is to find out if the - top - or - left - property is<br>
a string and provide the CSS units if it is:-<br>
<br>
var positionMod = (typeof divStyleRef.top == 'string')?"px":0;<br>
<br>
The - positionMod - value is set to the string "px" if the type of the -<br>
top - property is "string" else it is set to the number zero. This means<br>
that, when the - top - and - left - properties are set, using the<br>
addition/concatenation operator - + - to append - positionMod - to the<br>
calculated position values results is that browsers that are expecting<br>
string values with CSS units will get a string with the units on the end<br>
and browsers that are expecting numeric values will get numbers<br>
(unmodified by the addition of zero). So to set the position of the<br>
DIV:-<br>
<br>
divStyleRef.top = vPos + positionMod;<br>
divStyleRef.left = hPos + positionMod;<br>
<br>
And that is enough from me. You will have to get someone else to tell<br>
you how to get the dimensions for the DIV/image.
