title: Image button inside of form, don't want to submit
body: <p>I have a form with an image button inside of it, and this image button is submitting the form.  How do I override this functionality?</p>
  
  <pre><code>&lt;form&gt;&lt;input type="image" src="/images/arrow.png" id="imageButton" onClick="javascript:autofill();"/&gt;&lt;/form&gt;
  </code></pre>
