Thanks for putting this list together and making it available for all to see. Nice job.
cheers
HA! thanks i put it together for me so i could have it where ever I am. Did not think anyone read my blog. =\ hehe
If you find anything that is missing please feel free to tell me.
Very nice list here… thanks!
just posting yet another one
Sardalya: http://www.sarmal.com/sardalya/
License: free for uncommercial use; almost free for commercial use.
Description: s@rdalya, is a cross-browser interface that aims to make dynamic HTML programming easy and fun. It is a cross-browser compatible system which is designed to work in all DOM-supporting browsers.
Though the developer doesn’t test on a Mac, I encountered no problems viewing all of the many DHTML samples he provides. Sardalya includes Ajax functions as well as a comprehensive DOM-based DHTML library.
The library received and “A grade” from musingsfrommars.org: http://www.musingsfrommars.org/2006/03/ajax-dhtml-library-scorecard.html
In its blog, the developer says that the next version of the library will include:
* A better AJAX integration.
* And more objects to play with(such as Effect object for scheduled transitions such as background fades, or ModalDialog? object which generates a DOM generated modal dialog, which is a cross-browser DOM-implementation of IE’s modal dialog, which is not being used much because it is vendor-specific and not supported in other browsers.
Pros:
* Object-oriented.
* Flexible, easily extendible.
* Works in almost any modern browser.
* Independent of OS.
* Lightweight when you consider what is does.
Cons:
* Since it is being constantly developed, the documentation may not be in sync with the most recent version. However viewing the sources of examples are adequate to learn how to use the API.
Cheers,
You might want to include Backbase in your list: http://www.backbase.com. One of the most mature AJAX Development Platforms; free for non-commercial use; excellent documentation, and an active developer community at http://www.backbase.com/forum. It’s comprehensive, open, and easy-to-use.
Great list Ian. I just posted something similar (on a much smaller scale), but focused on providing links to tutorials for beginners. I included some of the more “recognizable” libraries; I have to admit, I had no idea there were so many more. Thanks.
Great Job Author, Thanks a lot for posting all the stuff at one place, thanks a lot……Well Done, its very useful.
Hi All Experts,
I want to use AJAX (Asynchronous JAVA script with XML ). How can i Optimize the site SEO.

Ok, ok, let’s just say that this is a list of EXCELLENT RESOURCES. You are a legend for providing these! I was struck, most especially, when I saw you mention AFLAX – that application, I think, is going to be super useful to me. Not to mention the others, this is an excellent list for a newbie like me.
The web is truly a fantastic place. Time to bookmark your site!
Great list, a like this sites, thx
