ie中还好，其他浏览器不知道怎么搞
function test(event) {
if (window.event) {
if (event.clientX > document.body.clientWidth && event.clientY < 0 || event.altKey) {
event.returnValue = "确定要退出本页吗?";
}
} else {
event.returnValue = "确定要退出本页吗?";
}
}
</script>
</head>
<body onbeforeunload="test(event)">
function test(event) {
if (window.event) {
if (event.clientX > document.body.clientWidth && event.clientY < 0 || event.altKey) {
event.returnValue = "确定要退出本页吗?";
}
} else {
event.returnValue = "确定要退出本页吗?";
}
}
</script>
</head>
<body onbeforeunload="test(event)">

用prototype.js的Event.observe()方法监听window的unload事件就可以捕获了。
示例代码如下：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<script type="text/javascript" src="./prototype.js"></script>
<script>
function a()
{
alert("onload");
}
function b()
{
alert("unload");
}
</script>
</head>
<body>
<script>
Event.observe(window, "onload", a);
Event.observe(window, "unload", b);
</script>
</body>
</html>
