I've been looking around JQuery libraries for the URL hash, but found none that were good. There is the "history plugin", but we all know it's buggy and isn't flexible.
I am loading my pages inside a div. I'll need a way to do back/forward along with the url hashing.
mydomain.com/#home mydomain.com/#aboutus mydomain.com/#register
What's the best library that can handle all of this?
They were all quite hard to setup, I did get jQuery.history working but it still had problems with IE7. So I changed to BBQ and it worked fine across all our target browsers (IE6, IE7, IE8, Fx3).
So I recommend the jQuery BBQ plugin.
Edit: here's a blog post I just wrote which demonstrates jQuery BBQ with cascading dropdowns.
