我想在DHTML EDIT Control.上按右键弹出alert()

<object id=DHTML classid=clsid:2D360201-FFF5-11D1-8D03-00A0C959BC0A" VIEWASTEXT></object>
<script language="javascript" for="DHTML" event="ShowContextMenu">
alert("你点击了鼠标右键！hehe！");
</script>

你真行！
能不能在iframe上点右键也alert()呢？

<iframe id=demo></iframe>
<script>demo.document.designMode="on"</script>

<object id=DHTML classid=clsid:2D360201-FFF5-11D1-8D03-00A0C959BC0A" VIEWASTEXT></object>


<script language="javascript" for="DHTML" event="ShowContextMenu">
alert("你点击了鼠标右键！hehe！");
</script>

<iframe id=demo name=demo></iframe>
<script language=javascript>demo.document.designMode="on";</script>

<object id=DHTML classid=clsid:2D360201-FFF5-11D1-8D03-00A0C959BC0A" VIEWASTEXT></object>


<script language="javascript" for="DHTML" event="ShowContextMenu">
alert("你点击了鼠标右键！hehe！");
</script>

<script language=javascript>
function document.demo.document.oncontextmenu()
{
alert("你在 Iframe 里点击了鼠标右键！hehe！");
return false; //屏蔽系统的右键菜单
}
</script>
