That won't work because $() *always* returns a valid jQuery object even if
there are no matching elements. This allows you to write code like
$('.foo').hide() without worrying about whether there are any elements with
class="foo" or not.
Instead (as pointed out elsewhere in the thread), check the .length
property.
