title: Prototype Event.StopPropagation for IE >= 8
body: <p>I understand the proper way to handle event.stopPropagation for IE is</p>
  
  <pre><code>if(event.stopPropagation) {
      event.stopPropagation();
  } else {
      event.returnValue = false;
  }
  </code></pre>
  
  <p>But is it possible to prototype Event so that I don't have to do the check each and everytime I use stopPropagation?</p>
  
  <p>This question seemed helpful: <a href="https://stackoverflow.com/questions/10617014/javascript-event-prototype-in-ie8">JavaScript Event prototype in IE8</a> however I don't quite understand the accepted answer and how it is a prototype that can essentially be set and forget.</p>
