 <li>level 1</li>
 <li>
  <ul style="widht:??;">
   <li>level 2</li>
   <li>level 2</li>
  </ul>
 </li>
 <li>level 1</li>
</ul>

The width() method of jQuery will give you the calculated width of an element:

$(function(){
  $('#menu li:has("ul")').each(function(){
    alert($(this).width());
  });
});

Get the current computed width for the first element in the set of matched elements.
