Jquery - Publish and Subscribe?

Question

Hi there,

Is there such a thing as publish and subscribe for use with jquery to send msgs from 1 javascript page to another.. Using the same idea behind ajax publish and subscribe?

I would like to use the pattern for communication between pages, i have been using a javascript framework lately but recently converted back to jquery and would love to continue using this.

Any ideas where i should start? and which implementation to use if more than 1 exists..

Thanks

jQuery is just a library providing set of utility functions. It is not a programming language. It is not Ajax.

Ajax is a design pattern. It is not a programming language. It is not a library.

Ajax publish-subscribe is just a more specific design pattern that uses the Ajax pattern.

There is no reason it can't be implemented using jQuery.

I think you're looking for an implementation of the bayeux protocol written in jquery.

A comet plugin that uses the bayeux protocol can be found here

jQuery is a simple JS toolkit that makes working with the DOM easier.

What you need is something like strophe. It uses XMPP via BOSH. There is a video, where the creator describes it.

Another option is the Bayeux protocol. There are implementations in Dojo and jQuery.
