title: Testing the type of a DOM element in JavaScript
body: <p>Is there a way to test the type of an element in JavaScript? </p>
  
  <p>The answer may or may not require the prototype library, however the following setup does make use of the library.</p>
  
  <pre><code>function(event) {
    var element = event.element();
    // if the element is an anchor
    ...
    // if the element is a td
    ...
  }
  </code></pre>
