I want to make a confirmation before user leaving the page.
(我想在用户离开页面之前做出确认。)
If he says ok then it would redirect to new page or cancel to leave.(如果他说好，那么它将重定向到新页面或取消离开。)
I tried to make it with onunload(我尝试使用onunload来实现它)
<script type="text/javascript">
function con() {
var answer = confirm("do you want to check our other products")
if (answer){
alert("bye");
}
else{
window.location = "http://www.example.com";
}
}
</script>
</head>
<body onunload="con();">
<h1 style="text-align:center">main page</h1>
</body>
</html>
But it confirm after page already closed?
(但它确认页面已经关闭后？)
How to do it properly?(怎么做得好？)
It would be even better if someone shows how to do it with jQuery?
(如果有人用jQuery演示如何做到这一点会更好吗？)
