In order to be able to answer exactly to your question, I need you to define what do you understand by advanced topics in AJAX?
I think that you can find some interesting chapters:
- AJAX Chat
- SVG (Scalable Vector Graphics) with AJAX
- AJAX Grid
- AJAX RSS Reader
- AJAX Drag and Drop
and a free chapter implementing a whiteboard solution and another one implementing an AJAX Chat with JSON. You can download them at
http://ajaxphp.packtpub.com/ I hope this answers your question!
