Two new AJAX have been released recently.
Yahoo AJAX Patterns has code and a set of patterns published under a BSD/Creative Commons license.
IBM’s AJAX Toolkit Framework is IBMs version.
Of course, Microsoft have their own version, called Atlas that’s built into ASP.NET 2.0.
I love the responsiveness of AJAX apps, but I hate breaking the back button.
What makes you think AJAX will break the back button? Or have I inferred a causal relationship in your commehnt that doesn’t exist?
I’m not necessarily condoning/recommending AJAX, but if you’re going to do it, a set of libraries would be a great help. It’s a bitch to try to sort out on your own.
The Back button’s overrated.
I see that the cross-browser rating of DHTML/AJAX libraries has been compiled – wtih dozens reviewed. In summary: Yahoo good, Microsoft bad.
