title: increment variable on set interval using javascript?
body: <p>First of all this is the mini javascript script:</p>
  
  <pre><code> f = 1
   $(".thumb").hover(function() {
         intervalId = setInterval($(this).text(f++), 400));
    });
  </code></pre>
  
  <p>Im trying to get the .thumb text to increase while the users moise is over it, It increases when i hover out and hover over again, but i want to increase while the user is hovered on top of the element.</p>
