Dont understand your issue. the only javascript served by this page should be

  <script type="text/javascript">
  function byId(id) {
    return document.getElementById(id);
  }

  function vote(node) {
    var v = node.id.split(/_/);   // {'up', '123'}
    var item = v[1];

    // hide arrows
    byId('up_'   + item).style.visibility = 'hidden';
    byId('down_' + item).style.visibility = 'hidden';

    // ping server
    var ping = new Image();
    ping.src = node.href;

    return false; // cancel browser nav
  } </script>

for the <a> links, as such:

  <a id=up_7666264 onclick="return vote(this)" href="vote?for=7666264&amp;dir=up&amp;xxxx">

and this makes it surely works correctly even without javascript.
