Class selector doesn't work as expected when specifying top

Description

var $tst =  $("#tst");
$(".foo span", $tst)

does not find the span on this HTML

<div id="tst" class="foo">
	<span>xxx</span>
</div>

I can understand and would expect that code not to regard a ".foo" outside of $tst. But shouldn't it regard the .foo on $tst ?

$(y,x) is the same as $(x).find(y), so no. It's best to ask these questions on the forums rather than the bug tracker.

It is *not* working. And it doesn't work with .find() either.

If you think that is the best and least suprising solution this way and intended behaviour, at least document it as such.

That's because you have misunderstood the .find() method, which finds *descendant* elements. Your #tst element is not a descendant of itself.

at least document it as such.

 http://docs.jquery.com/Traversing/find#expr

"Searches for descendent elements that match the specified expression."

The SPAN element I am searching is a descendent.

I never expected the context itself to be found. I was always searching an descendent. I just expected the context to be regard when looking for the class.
