How to use

See Demos/index.html

You can create an instance of ScrollLoader via the following code

new ScrollLoader({
	onScroll: function(){
		// User has reached a certain boundary
		// Let's make a Request for new content
		
		this.detach(); // While waiting, we detach the listener so the event does not fire accidentally
		
		var scroll = this; // Save a reference
		new Request(url, {
			onSuccess: function(text){
				new Element('div', {text: text}).inject(myElement); // Add the new content
				
				scroll.attach(); // Attach the event again so the event fires when you hit the bottom again
			}
		}).get();
	}
});
