title: jQuery clearInterval not working
body: <p>I have the following hover function </p>
  
  <pre><code>function tt_attachToBase(){
          jQuery.each(bases,
              function(index,base){
  
                  jQuery(base).hover(function() {  
                           jQuery(base).showTipTimer = setInterval( function(){tt_locateBase(base);} , 3000 ); 
                               },  
                              function() {  
                                  clearInterval(jQuery(base).showTipTimer);
                                  tt_hideTip();
                                      }
  
                      }); 
              }
  
          );
  </code></pre>
  
  <p>inside tt_locateBase() I also clear interval like this</p>
  
  <pre><code>tt_locateBase(base){
  clearInterval(jQuery(base).showTipTimer);
  //code to sidplay tooltip
  }
  </code></pre>
  
  <p>the tooltip does display after an interval, but the interval it seems is never cleared since the tooltip keep recurring over base. what am I doing wrong? </p>
