how do I find out if the cursor is in the bounds of an element
<p>I'm creating a drag and drop application and what I want to do is while the user is dragging an element get if the cursor is over certain other element.</p>

<p>Heres the flow:</p>

<p>User starts dragging an element around the page<br>
When the mouse gets over certain parts I want to make an ajax call.  </p>

<p>Because I know the elements and their bounds via jquery I just want the best way to make the check.</p>
