/*
Behaviour v1.1 by Ben Nolan, June 2005. Based largely on the work
of Simon Willison (see comments by Simon below).

Description:

Uses css selectors to apply javascript behaviours to enable
unobtrusive javascript in html documents.

Usage:

var myrules = {
'b.someclass' : function(element){
element.onclick = function(){
alert(this.innerHTML);
}
},
'#someid u' : function(element){
element.onmouseover = function(){
this.innerHTML = "BLAH!";
}
}
};

Behaviour.register(myrules);

// Call Behaviour.apply() to re-apply the rules (if you
// update the dom, etc).

var Behaviour = {
	list : new Array,

	register : function(sheet){
		Behaviour.list.push(sheet);
	},

	start : function(){
		Behaviour.addLoadEvent(function(){
			Behaviour.apply();
		});

	apply : function(){
		for (h=0;sheet=Behaviour.list[h];h++){
			for (selector in sheet){
				list = document.getElementsBySelector(selector);

				if (!list){
					continue;
				}

				for (i=0;element=list[i];i++){
					sheet[selector](element);

		} else {

				func();
			}
		}
	}
}

The following code is Copyright (C) Simon Willison 2004.

document.getElementsBySelector(selector)
- returns an array of element objects from the current document
matching the CSS selector. Selectors can contain element names,
class names and ids and can be nested. For example:

elements = document.getElementsBySelect('div#main p a.external')

Will return an array of all 'a' elements with 'external' in their
class attribute that are contained inside 'p' elements that are
contained inside the 'div' element which has id="main"

New in version 0.4: Support for CSS2 and CSS3 attribute selectors:
See http://www.w3.org/TR/css3-selectors/#attribute-selectors

Version 0.4 - Simon Willison, March 25th 2003
-- Works in Phoenix 0.5, Mozilla 1.3, Opera 7, Internet Explorer 6, Internet Explorer 5 on Windows
-- Opera 7 fails
