title: Trigger event after slideUp or slideDown is completed
body: <p>I'm doing a simple slideUp animation on an object.
  I want to add attribute tag to the the element after animation completes.
  How can i get this to work ?</p>
  
  <pre><code>if($(this).is(':visible')) {
    if(config.animate=='true')                    
      $(this).slideUp(options.animationTime);   //After animation ends do $(this).attr('shown','true');
    else 
      $(this).hide();             
  }
  </code></pre>
