$("*[id]")

should work, and - for the record -

$("*:not([id])")

+1 But I think I'd probably limit the query to descendants of `body` just to make it a little quicker. `$('body [id]')` – user113716 Sep 10 '10 at 13:52

Fair enough. :o) I certainly don't disagree with your assessment of the performance difference. Such is the case of many performance-related 'best practices' we may do. – user113716 Sep 10 '10 at 15:40

$('[id]')

This will grab all elements that have an 'id' attribute.

Or to get all divs with an 'id' attribute you can do:

$('div[id]')
