Using jQuery, how can I trigger an event when a user hovers over an element but NOT over one of the element's child elements?

hover() is a shortcut for mouseenter() and mouseleave(), but you want the behavior of mouseover(), not mouseenter(). Check out the demo on this page: http://api.jquery.com/mouseover/#example-0

Thanks but I think you missed the point of my question.  I want to know how to select an element without also selecting its children.  I used hover() as an example.  

$('#selection<BUT_NO_CHILDREN').hover(.....

You can't do that with selectors. You have to trap the event on the descendants so it doesn't bubble up to the parent.

$(document).ready(function() {
  $('#selection').mouseover(function() { alert('You are hovering over the red area NOT the blue area.') });
  $('#selection').find('*').mouseover(function(e) { e.stopPropagation(); return false; });
});

P.S. Is there a particular reason why you're using that old version of jQuery? The current version is 1.6.4.
