any debugging tools for Ajax

Also, what Javascript books are recommended that would be great to accompaniment an Ajax book?

To answer the question from the topic title about debugging tools for Ajax:

FIREBUG!!! http://www.getfirebug.com/

It's only for Firefox, but it's (probably) the only debugging tool you need.

You'll actually need books on three topics:
-JavaScript
-DHTML
-JavaScript + DHTML

For just JavaScript, the Rhino Book from O'Reilly is indispensable:

For the last two, I must confess that I usually just look through the W3C specs and the Mozilla developer manuals, which is sub-optimal. Anyone care to recommend some good ones?

People always forget (myself included) that JavaScript really is a powerful language in its own right. (At a previous company, we wrote apps in pure JavaScript which was then compiled to Java bytecode.) But having just JavaScript in a browser is useless. What makes JavaScript so powerful in the browser is that browsers expose access to their underlying internals through the DOM.

This is why you really need three books. The first to learn JavaScript by itself properly. The second to see how browsers expose the DOM to JavaScript. The third to see what neat stuff you can do w/ the combination.

For DHTML, I swear by the flamingo:

Forsooth! How could I forget the flamingo!

Yes, between the Rhino and the Flamingo, you should be off to a good start.

And if you're interested in CSS too, I remember Bear recommending Eric Meyer's CSS : http://meyerweb.com/eric/css/

Those Rhino and Flamingo are so massive !!
I'll stick with Internet
