title: How to submit a form with specific fieldset
body: <p>I have a form like this:</p>
  
  <pre><code>&lt;form name="paymentForm" id="paymentForm" action="/submit.jsp" method="post"&gt;
      &lt;fieldset id="ccData"&gt;
          &lt;input id="ccNumber" name="ccNumber"/&gt;
      &lt;/fieldset&gt;
      &lt;fieldset id="otherData"&gt;
          &lt;input id="requestId" name="requestId"/&gt;
      &lt;/fieldset&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>When you slick submit, I would like to submit(via ajax) only #ccData filedset to some different url (e.g. submitCC.jsp) and based on response I want to submit full form to actual url.</p>
  
  <p>How can I achieve that ?</p>
