title: How do you handle a form change in jQuery?
body: <p>In jQuery, is there a simple way to test if <em>any</em> of a form's elements have changed?</p>
  <p>Say I have a form and I have a button with the following <code>click()</code> event:</p>
  <pre><code>$('#mybutton').click(function() {
    // Here is where is need to test
    if(/* FORM has changed */) {
       // Do something
    }
  });
  </code></pre>
  <p>How would I test if the form has changed since it was loaded?</p>
