Can anyone offer some general comments on what jQuery does and does not do from a cross-browser standpoint?
Any tips for debugging jQuery/JS in IE?
I’ve seen very, very few differences in behavior across browsers. That said, jQuery is only good so long as you’re using jQuery – once you step outside of built-in event handling and DOM traversal, you’re gonna end up running into browser incompatibilities anyway.
VS2008 works reasonably well for debugging JS in IE; without further information on the sorts of problems you’re encountering, i can’t really suggest anything else.
