Description:

Like any good Javascript framework would, jQuery includes Ajax functionality into its core. In particular, though, jQuery has some interesting ways it approaches event handling with Ajax responses. We’re going to dive into this Ajax event mechanism, and see what fun we can have with extending it.

This talk will first review the various Ajax events and some common ways they are used. Then, we’ll investigate jQuery source code and see how each is accomplished. Armed with this knowledge, we’ll talk about some scenarios where you might want to extend these events with extra functionality, or even add your own custom Ajax events.

To move from the theoretical into the concrete, we will discuss two jQuery Ajax plugins I released, mpAjax and flXHRproxy, and look at how each needed in its own way to hook into the Ajax event mechanism and extend it.
