右擊鼠標顯示快捷菜單：
  <script language="JavaScript">
   document.onmousedown = function popUp() {
    menu = document.all.itemopen
    if (event.button == 2) {
    newX = window.event.x + document.body.scrollLeft
    newY = window.event.y + document.body.scrollTop
    menu.style.display = ""
    menu.style.pixelLeft = newX
    menu.style.pixelTop = newY
    }
    else if (event.button == 1)
    {
     menu.style.display = "none"
    }
   }
  </script>

屏蔽IE默認的WinForm快捷菜單：
  <script language="JavaScript">
   var message="";
   function clickIE()
   {
    if (document.all)
    {
     (message);
     return false;
    }
   }
   function clickNS(e)
   {
    if (document.layers||(document.getElementById&&!document.all))
    {
     if (e.which==2)
     {
      newX = window.event.x + document.body.scrollLeft
      newY = window.event.y + document.body.scrollTop
      menu = document.all.itemopen
      if ( menu.style.display == "")
      {
       menu.style.display = "none"
      }
      else
      {
       menu.style.display = ""
      }
      menu.style.pixelLeft = newX
      menu.style.pixelTop = newY
     }
     if (e.which==3)
     {
      (message);
      return false;
     }
    }
   }
   if (document.layers)
   {
    document.captureEvents(Event.MOUSEDOWN);
    document.onmousedown=clickNS;
   }
   else
   {
    document.onmouseup=clickNS;document.oncontextmenu=clickIE;
   }
   document.oncontextmenu=new Function("return false")
  </script>
