如何在本页内屏蔽IE工具栏？

    <script>
 if (!window.opener || window.opener!='iOASLogin'&&window.name!='iOASWin'){
  window.opener = 'iOASLogin';

  var feature = "scrollbars=no,menubar=no,resizable=yes,location=no,status=no,toolbar=no";
  var win = window.open("iOASLogin.aspx","iOASWin",feature);
    win.resizeTo(screen.width,screen.height);
    
  window.close(); 
 }
</script>
<script language="javascript">

  function FocusTextBox(page){  
   document.all(page).focus();
  }
</script>
