Snippet from slashdot post — “Computerworld has a long excerpt from a book by Edmond Woychowsky about how to code Web pages in AJAX. It gives a good explanation of how the technology works, and also has some visuals and code snippets that you can play with. From the article: ‘Beyond the XMLHTTP Request object, which has been around for several years as a solution looking for a problem, there is nothing weird needed. Basically, it is how the individual pieces are put together. When they’re put together in one way, it is nothing more than a pile of parts; however, when put together in another way, the monster essentially rises from its slab.'”
So How Do You Code an AJAX Web Page?
