The online references at [w3schools.com...] and
the JavaScript & DHTML Cookbook by Danny Goodman
worked well for me.
I was a COMPLETE newbie at javascript (never touched it before) when I bought the book a few weeks ago. I have learned so much. In fact, you're actually at an advantage not knowing any javascript because browser implementation and DOM specifications have changed so much in recent years that it's easier if you start with a blank slate. (Modern DOM scripting is very different from old-school javascript from only a few years back)
However... you really should have basic programming skills in any language to read the book... since it doesn't go into programming basics that apply to any language (like loops, variable declaration, etc)
The second half of the book goes into AJAX -- but the book starts off very simple and builds on new concepts and techniques discussed. AJAX is very complicated and you definitely have to master the topics presented in the first half of the book to delve into it.
Hope that helps :-)
