dialog link disappears after onclick

dialog link disappears after onclick

hello, i have this code for a dialog box,

  1.             <script language="javascript">
                function dialog() {
                      $("#dialog").dialog({ modal: true }).load("/;contact");
                  }
                </script>
                To contact us:
                <a id="dialog" style="text-decoration: underline"
                href="#" onclick="dialog()">Contact</a>






this loads the contact form correctly, but the <a href> link disappears after i have made the click.

what am i missing?

thanks
