title: clearTimeout when a function gets called multiple times
body: <p>I have an alert message bar that slides down when the user clicks a specific link. The alert bar slides back up after a specified period. If the user clicks this link multiple times, I would like to reset the timer, slide the alert bar back up and then slide it down again (reseting the timer).</p>
  
  <pre><code>$(document).ready(function(){
  
      $('#main_container').live('click', function(){
          $('.answer_yes').click (function(){
  
  
              if ($('#topbar_alert').is(':visible')){
  
                  clearTimeout(slideUpTimer)  
  
                  }
  
                  $('#topbar_alert').slideDown(300);
                  $('#topbar_alert_container').empty();
                  $('#topbar_alert_container').append('Alert Created!');
  
                  var slideUpTimer = setTimeout(function() {
                      $('#topbar_alert').slideUp(300);
                  },8000);
  
          });
      });
  
  }); 
  </code></pre>
  
  <p>So everything works except the clearTimeout portion. If you click the link, the alert bar slides down and then slides back up after the setTimeout finishes. But if you click the link multiple times, it doesn't reset the alert bar. </p>
