The .contains method is only available on the jQuery object but not on Wrapped DOM Nodes, this is inconsistent and unintuitive.


to me $('#something').contains(...) seems very logical, additional it would be nice if that new method could handle jQuery wrapped DOM Nodes too

Isn't this exactly what jQuery.fn.has is for?

This functionality already exists in the form of find().length, take a look:

if ( poop.find('shoopdawoop').length ) { 
  /* contains shoopdawoop */

The $.fn.contains that's envisioned here was in pre-release versions of jQuery 1.4 and I was opposed to it then because

a) $.fn.contains shouldn't be different from the pseudoselector :contains, which filters by text

b) it's just a shortcut to .has("foo").length

I don't really think $.contains is unintuive per se, you just have to understand that it's a low level utility for doing a specific job quickly, not a generic traversal method.
