title: JQuery slideToggle() current show/hide state property?
body: <p>What is the easiest way to programmatically find the current toggle state of a DOM element when using the slideToggle() function in jquery 1.3.2?  </p>
  
  <p>I expected there to be a property for this, but I can't seem to find one.  Directly checking the CSS display or height seems like a hack, but maybe that's what one is expected to do. </p>
