答案：<script language="javascript">
<!--
 
if (window.Event) 
  document.captureEvents(Event.MOUSEUP); 
 
function nocontextmenu() 
{
 event.cancelBubble = true
 event.returnValue = false;
 
 return false;
}
 
function norightclick(e) 
{
 if (window.Event) 
 {
  if (e.which == 2 || e.which == 3)
   return false;
 }
 else
  if (event.button == 2 || event.button == 3)
  {
   event.cancelBubble = true
   event.returnValue = false;
   return false;
  }
 
}
 
document.oncontextmenu = nocontextmenu;  // for IE5+
document.onmousedown = norightclick;  // for all others
//-->
</script>
