点击关闭按钮时，计算机会计算出你在本页停留了多长时间！
其实很简单，只须将如下代码加入<body>与</body>区即可(还要注意将<body>改为
<body onUnload="bye()">):
<
script LANGUAGE="Javascript"><!-- Begin
pageOpen = new Date();
function bye() {
pageClose = new Date();
minutes = (pageClose.getMinutes() - pageOpen.getMinutes());
seconds = (pageClose.getSeconds() - pageOpen.getSeconds());
time = (seconds + (minutes * 60));
if (time == 1) {
time = (time + " second");
}
else {
time = (time + " seconds");
}
alert('您在本页停留了' + time + '.谢谢！!');
}
// End -->
<
/script>
