title: Will JQuery override existing inline event handlers?
body: <p>I have a site which is built out of many iframes.
  I am working on monitoring user activity - like when user clicks or keydown.</p>
  
  <p>This is only to see if user is idle or not.</p>
  
  <p>For this, I am drilling down to all iframes,its div tags and registering hover and click events.
  Meanwhile I dont want to override/break existing inline event handlers which are defined by the application.</p>
  
  <p>Will jquery override exiting eventhandlers? If yes, how can check this to make sure I dont do this?</p>
  
  <p>Here is my usage.</p>
  
  <pre><code>$(divElementObj).click( function() {
      alert("div click");
  });
  </code></pre>
