title: Javascript form submit: Object doesn't support this property or method (IE7)
body: <p>I'm trying to submit a form with javascript. Firefox works fine but IE complains that "Object doesn't support this property or method" on the submit line of this function:</p>
  
  <pre><code>function submitPGV(formName, action)
  {
      var gvString = "";
  
      pgVisibilities.each(function(pair) {
          gvString += pair.key + ":" + pair.value + ",";
      });
  
      $('pgv_input').value = gvString;
  
      var form = $(formName);
      form.action = action;
      form.submit();
  }
  </code></pre>
  
  <p>Called here:</p>
  
  <pre><code>&lt;a href="javascript:submitPGV('ProductGroupVisibility','config/productgroupvis/save')"&gt;
  </code></pre>
  
  <p>Here's the form:</p>
  
  <pre><code>&lt;form id="ProductGroupVisibility" action="save" method="post"&gt;
      &lt;input type="hidden" name="ows_gv..PGV" id="pgv_input" value=""/&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>Any ideas?</p>
