title: jQuery - stop mouseover loop
body: <p>I need to stop the mouseover event if a condition is true and I don't really now how. I 've made this:</p>
  
  <pre><code>$('body').mouseover(function() {
      if ($('span.done').length &gt; 0) {
          alert('done!');
      }
  });
  </code></pre>
  
  <p>after the alert() is called, the mouseover should stop, and stop calling the allert.
  Any help is much appreciated. Thanks.</p>
