#Four Ways To Do Pub/Sub With jQuery and jQuery UI (in the future)

Between jQuery 1.7 and some of work going into future versions of jQuery UI, there are a ton of hot new ways for you to get your publish/subscribe on. Here are just four of them, three of which are new.

(PS: If you're unfamiliar with pub/sub, read the guide to it that Julian Aubourg and I wrote here http://msdn.microsoft.com/en-us/scriptjunkie/hh201955.aspx)

##Option 1: Using jQuery 1.7's $.Callbacks() feature:

$.Callbacks are a multi-purpose callbacks list object which can be used as a base layer to build new functionality including simple publish/subscribe systems. We haven't yet released the API documentation for this feature just yet, but for more information on it (including lots of examples), see my post on $.Callbacks() here:

	//Use $.cookie('quickbrowse-debug', true, {expires: 7, path: '/'}) to set.
	// ... and $.cookie('quickbrowse-debug', null) to delete.
	var qbConsole;
	if(!$.cookie('quickbrowse-debug')) {
	qbConsole = {};
	qbConsole.log = function(){};
	} else {
	qbConsole = console;
	}

	boolean hasUpdated = false;
	boolean doneBuffering = false;
	long bufferTimeout = 500;

	// put this somewhere smart
	new Thread(new Runnable() {
	public void run() {
	while(!doneBuffering) {
	Thread.sleep(bufferTimeout);

	import Qt 4.7

	BorderImage {
	id: buttonbase

	signal clicked

	property int hitboxExtension : 20
	property alias text : label.text
	property bool pressed: hitbox.pressed && hitbox.containsMouse
