It’s time to introduce you guys to the Observer pattern. If you’ve been following this blog lately, you may have already had an introduction through my post talking about my jQuery plugin called JZ Publish/Subscribe. Well, here we’ll be talking about a few other ways to implement the Observer pattern, so you’ll know the method that works best for you and your application.
If you don’t already know, JZ Publish/Subscribe is a jQuery plugin that I developed to add a simple, but powerful Pub/Sub feature to the jQuery utility functions. I’m guessing there are some people out there who don’t understand what Pub/Sub is, how to use it, or why to use it. I’m here to bring some answers and give a specific example of how JZ Publish/Subscribe can be used.
