How can I check if an element is within another one in jQuery?

Question

Is there any direct way in JavaScript or jQuery to check if an element is within another one.

I\'m not referring to the $(this).parent as the element I wish

Answer 1

With jQuery >=1.4 (2010) you can use the very fast function jQuery.contains()

This static method works with DOM elements, not with jQuery elements and returns true or false.

jQuery.contains( container, descendant )

Example: To check if a element is in the document you could do this:

jQuery.contains( document.body, myElement )
