I am loading an external file 'contact_us.aspx' into a jquery dialog box. the external page contains a form.

When the submit button is pressed it closes the dialog box and changes the page to contact_us.aspx. is my code correct or is there a different way of doing this. see my code below, thanks.

This JS is in y masterpage:

<script type="text/javascript">
        $(document).ready(function() {
            var dialogOpts = {
                modal: true,
                bgiframe: true,
                autoOpen: false,
                height: 500,
                width: 500,
                open: function(type, data) {
                    $(this).parent().appendTo(jQuery("form:first"));
                }
            }

            $("#genericContact").dialog(dialogOpts);   //end dialog

            $('a.conactGeneric').click(
              function() {
                  $("#genericContact").load("contact_us.aspx", [], function() {
                      $("#genericContact").dialog("open");
                  }
                 );
                  return false;
              }
           );

        });
    </script>

The external file 'contact_us.aspx' which is loaded into the dialog box, when the link is clicked.
