title: Multiple Listeners for Single Event
body: <p>In JavaScript we are allowed to set the multiple listeners on the single event. For example:</p>
  <pre><code>element.addEventListener('click',startDragDrop,false);
  element.addEventListener('click',spyOnUser,false);
  </code></pre>
  <p>I am planning to do the same in my project. I just want to be sure that it should not cause any problem with the order of the execution of the callback the way it is written on <a href="http://www.quirksmode.org/js/events_advanced.html" rel="nofollow noreferrer">QuirksMode</a>. It says that <strong>W3C model does not state which event handler is fired first, so you cannot assume <code>startDragDrop()</code> is executed before <code>spyOnUser()</code>.</strong> But I want to be sure that my <code>startDragDrop</code> should be executed first then <code>spyOnUser()</code>. Is there any way I can make it sure?</p>
