title: What html tags support the onload/onerror javascript event attributes?
body: <p>I'm familiar with the typical use of <code>onload</code>, as in the following:</p>
  
  <pre><code>&lt;body onload="alert('Hello, World!');"&gt;
  ...
  &lt;/body&gt;
  </code></pre>
  
  <p>What are all the html elements that fire a load event? (thus executing javascript supplied in an onload attribute)</p>
  
  <p>For example, <code>img</code> is one such tag that will execute the javascript supplied in an <code>onload</code> attribute when <code>some.png</code> has loaded:</p>
  
  <pre><code>&lt;img onload="someImgLoaded()" src="some.png" /&gt;
  </code></pre>
