javascript memory leaks

Question

DOM:

Answer 1

Yes, because jQuery maintains a list of the attached event handlers to make unhooking them easier and in order to explicitly unhook them for you when the page is unloaded (which works around a more serious memory leak in IE). (So does Prototype, can't speak for other libs.) The solution is to unhook them before removing the elements (either directly, or via empty).
