XMLHttpRequest & Ajax Tutorials

By way of a simple addressbook, Getting Started with Ajax provides concise instructions to building a widget with Ajax and fleshes out two examples: one that returns HTML and another that returns XML.

I haven't had time to read the free sample chapters yet, but this offering from Sitepoint looks interesting as it promises, amongst other things, to teach one how to Create an AJAX search application that pulls data from Amazon, del.icio.us, and Google, Fix the Back button problem, Use JSON, YAML, and XML to communicate with the server and Build an AJAX drag 'n' drop chess game.

The book also comes with a free 16 minute video about Ajax.

This article aims to give you an introduction to the foundations of remote scripting, in particular, the emerging XMLHttpRequest protocol. We'll then walk through an example application that demonstrates how to implement that protocol, while creating a usable interface.
