网页禁止右键代码

<!--禁止鼠标右键代码-->
<noscript><iframe src=*.html></iframe></noscript>
<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>

2.只要下面这段代码，就能搞定在网页中又禁止复制、又禁止键盘复制、还能禁止选择。
<script language="Javascript">
document.oncontextmenu=new Function("event.returnValue=false");
document.onselectstart=new Function("event.returnValue=false");
</script>
