先来看看frames.htm页面的源代码：
<html> <head>
<title>网页跨框架菜单 from MSDN</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
</head>
<frameset rows="92,*" cols="*" framespacing="4" frameborder="yes" border="4">
<frame src="top.htm" name="topFrame" scrolling="NO" >
<frame src="bottom.htm" name="mainFrame">
</frameset>
<noframes><body>
</body></noframes>
</html>
再来看看top.htm页面的源代码：
<html><head>
<title>MSDN的示例</title>
<script>
var oPopup = window.createPopup();
function richContext()
{
var lefter2 = event.offsetY 0;
var topper2 = event.offsetX 15;
oPopup.document.body.innerHTML = oContext2.innerHTML;
oPopup.show(topper2, lefter2, 210, 84, contextobox);
}
</script>
</head>
<body>
<span id="contextobox" style=" cursor:hand; margin-left:5px; margin-right:10px; background:#e4e4e4; width:300; height:40; padding:20px;" oncontextmenu="richContext(); return false" >Right-click inside this box.</span>
