title: jQuery doesn't submit a form
body: <p>I have the following HTML code:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt;
  
  &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;
  
  &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;
  
  &lt;head&gt;
      &lt;title&gt;IT-Services Umfrage - Fragen&lt;/title&gt;
  
      &lt;link rel="stylesheet" type="text/css" href="/IT/umfrage/../../style.css" /&gt;
      &lt;link rel="stylesheet" type="text/css" href="/IT/umfrage/css/umfrage.css" /&gt;
  
      &lt;script type="text/javascript" src="/IT/umfrage/../../inc/jquery-1.4.2.js"&gt;&lt;/script&gt;
      &lt;script type="text/javascript" src="/IT/umfrage/js/umfrage.js"&gt;&lt;/script&gt;
  &lt;/head&gt;
  
  &lt;body id="page-show"&gt;
      &lt;div class="ueberschriftsbalken"&gt;&lt;span&gt;IT-Services Umfrage - Fragen&lt;/span&gt;&lt;/div&gt;
      &lt;br /&gt;
      &lt;div id="content"&gt;
  
          &lt;form action="/IT/umfrage/Umfrage/save" method="post" id="umfrageForm"&gt;
              &lt;div class="frage radio"&gt;
                  &lt;p&gt;1. Wie professionell empfinden Sie das Auftreten der IT-Service Anlaufstelle?&lt;/p&gt;
                  &lt;label for="frage1_1"&gt;&lt;input type="radio" name="frage1" id="frage1_1" value="1" /&gt; Lausig&lt;/label&gt;&lt;br /&gt;
                  &lt;label for="frage1_2"&gt;&lt;input type="radio" name="frage1" id="frage1_2" value="2" /&gt; Schwach&lt;/label&gt;&lt;br /&gt;
                  &lt;label for="frage1_3"&gt;&lt;input type="radio" name="frage1" id="frage1_3" value="3" /&gt; Durchschnittlich&lt;/label&gt;&lt;br /&gt;
                  &lt;label for="frage1_4"&gt;&lt;input type="radio" name="frage1" id="frage1_4" value="4" /&gt; Gut&lt;/label&gt;&lt;br /&gt;
                  &lt;label for="frage1_5"&gt;&lt;input type="radio" name="frage1" id="frage1_5" value="5" /&gt; Hervorragend&lt;/label&gt;
              &lt;/div&gt;
              &lt;input type="submit" value="Antworten absenden" name="submit" id="submitbutton" /&gt;
          &lt;/form&gt;
      &lt;/div&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>When clicking on the submitbutton or when pushing the enter key, the form gets submitted. But when i try <code>$('#umfrageForm').submit()</code>, <code>$('form').submit()</code> or anything similar, nothing happens. In Firebug, the function only returns the DOM path to the form element.</p>
  
  <p>What could be the problem that prevents the form from being submitted?</p>
