30 Fresh AJAX Tutorials And Techniques

Using AJAX on websites and applications is pretty much taken for granted nowadays. Users expect it. They want to be able to edit a page in-place, they want search queries to be auto-suggested, and they want to be able to submit a form without refreshing the page. Why? Because those things make browsing quicker, easier and, more importantly, enjoyable.

As great as AJAX is, though, it is not for every website or application. Part of the developer?s job is to know exactly where AJAX (or any technology for that matter) is needed. Too little can lead to user frustration. Too much causes misunderstanding. A balance and some restraints are always needed.

In this round-up, we have collected 30 fresh AJAX tutorials and techniques, covering almost every aspect of AJAX development: forms, applications, polls, editing, parsing, visual effects and much more.
