jQuery test if element1 is descendant of element2

Question

Does anyone know a good way to test if one element, stored in a var, is the descendant of another, also stored in a var?

I don't need element1.isChildOf('selector'), that's easy.
I need element1.isChildOf(element2)

element2.find(element1).size() > 0 Does not seem to work.

I don't want to have to write a plugin the uses .each to test each child if I can avoid it.

Answer 1

If you're using 1.4, and are looking for a descendant rather than a child as your find() example implies, there's a has() method:

element2.has(element1).length > 0
