推荐答案
您的摘机方法没有在任何地方被调用.为此，您可以使用
Your unhook method is not getting called anywhere. To do so you can refresh the page using
您也可以在其中调用摘机的Javascript，如下图所示.
Javascript where you can call unhook also as shown velow.
<html>
<head>
<script type="text/javascript">
var hook = true;
window.onbeforeunload = function() {
if (hook) {
return "msg here"
}
}
function unhook() {
hook=false;
}
setInterval(function(){
unhook();
window.location.reload()
}, 60000);
</script>
</head>
<body>
</body>
</html>
在60000毫秒(即1分钟)后调用设置间隔的脚本，这使您可以先设置hook = false然后刷新.
The script in set interval is called after 60000 milli-seconds (i.e. 1 min) which allows you to first set hook=false and then refresh.
