#Four Ways To Do Pub/Sub With jQuery 1.7 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:

	{
	// http://www.jshint.com/docs/

	"jshint_options": {

	// prohibits the use of explicitly undeclared variables
	"undef": true,

	// prohibits the use of a variable before it was defined
	"latedef": true,

	class ApplicationController < ActionController::Base
	...
	before_filter :save_or_clear_session

	def save_or_clear_session
	if controller_name.eql?('sessions') and action_name.eql?('destroy')
	request.reset_session
	flash[:notice] = "Signed out successfully."
	end
	end
