title: Simple onload doesn't work in JSFIddle
body: <p><a href="http://jsfiddle.net/jzhang172/n5jb0159/" rel="noreferrer">http://jsfiddle.net/jzhang172/n5jb0159/</a></p>
  
  <p>Simple document.body.onload event should trigger a javascript alert, but doesn't work but it works fine in my text editor -> browser.  I switched the libraries around to jQuery to None (pure JS), still nothing, can someone explain to me what's going on and why it doesn't work in fiddle but works fine in my text editor?</p>
  
  <p>This works:</p>
  
  <pre><code>  &lt;body&gt;
      Why
      &lt;script&gt;
    document.body.onload = function(){
        alert("LOADED!");
    }
    &lt;/script&gt;
    &lt;/body&gt;
  </code></pre>
