There are hundreds (if not thousands) of articles out there on Ajax. Many of which are better than the one by Bob (No offense). I highly recommend you check out some other articles that will help give you a better idea of how to accomplish what you need. Here is a link to an Ajax tutorial that got me started:
http://rajshekhar.net/blog/archives/85-Rasmus-30-second-AJAX-Tutorial.html
A word of warning: the page has a gray background with white text. Why Ramus choose such a god awful color scheme, the world may never know. For the sake of your vision, I recommend copying and pasting the article into the text editor or your choice.

From what I've seen and read, you don't write back HTML. You send back
either text or XML that is parsed by the JS in the original page. That JS
also updates the existing page. So, when you send a response back from your
CGI program, you send it back out with the same concepts that we use for
CGI, but the parsing work is the extra steps required in the JS. Bob Cozzi
was supposed to write a follow on article to address the parsing side of it.
I do not know if he has yet.
