Beforeunload无法将用户重定向到另一个页面，如何在尝试关闭窗口/选项卡时将用户重定向到另一个页面/ URL？
问题描述：
我的以下代码无法将用户重定向到另一个页面：
My following code isn't working to redirect the user to another page:
$(window).on('beforeunload',function(){
window.location.href="http://www.google.com;
}) ;
我希望用户在尝试关闭标签时重定向到另一个页面。
实现此目的的替代方法是什么？
I want the user to be redirected to another page when he attempts to close the tab. What's the alternative and appropriate way to achieve this?
答
* 不要这样做 *
但是有可能获得用户的许可;你可以做到这样的事情（花了一些时间找到一个框架中很开心的网站）
*Don't do it*
But it is possible with the user's permission; you can achieve something like this (took me a while to find a website that was happy in a frame)
window.onbeforeunload = function () {
window.setTimeout(function () { // escape function context
window.location = 'http://bbc.co.uk';
}, 0);
window.onbeforeunload = null; // necessary to prevent infinite loop
// that kills your browser
return 'Press "Stay On Page" to go to BBC website!';
// pressing leave will still leave, but the GET may be fired first anyway
}
