Javascript，我可以“重定向"吗?用户在 onbeforeunload ?如果不能，如何 [英] Javascript, Can I "redirect" user in onbeforeunload? If cant, how to

问题描述

是否可以在用户关闭浏览器时重定向到另一个页面?

Is it possible to redirect to another page when the user closes the browser?

尝试:

1. 我试过onunload，不行

1. I tried onunload, does not work

window.onunload = function redirect(){...}

我也试过另一种方法，它也不起作用:

I also tried another method, it doesn't work either:

window.onbeforeunload = redirect(){...}

第三种方法，我想取消onbeforeunload(表示延迟关闭浏览器)，我调用重定向函数，window.confirm，如果是redirect，如果没有则关闭浏览器.但效果不佳.

The 3rd method, I want to cancel the onbeforeunload (means delay closing the browser), the I call the redirect function, window.confirm, if yes redirect, if no then close the browser. But it does not work as well.

还有什么办法吗??也许提示让用户选择是否在他/她关闭浏览器时重定向到新页面?我的想法快用完了...

Is there any other way?? Maybe prompt to let user select whether to redirect to new page when he/she close the browser? I'm running out of ideas...

推荐答案

你的 onbeforeunload 事件需要返回一个字符串(不等于 false)，浏览器会在它自己显示给用户的消息中包含这个字符串.

Your onbeforeunload event needs to return a string (that doesn't equate to false), the browser will include this string in its own message displayed to the user.

window.onbeforeunload = function(){
        location.assign('http://www.google.com');
        return "go to google instead?";
    }

但是，以用户能够理解要做什么的方式来表达您的消息将非常棘手.而且我不确定这在每个浏览器中是否都很强大，我只是在 Chrome 中尝试过，它有效，但我最终得到了一个无法关闭的选项卡！谢天谢地，我设法通过 Chrome 任务管理器杀死了它.

However, it's going to be really tricky to word your message in a way that the user would be able to understand what to do. And I'm not sure this is robust in every browser, I just tried it in Chrome, it worked, but I ended up with a tab I could not close! I managed to kill it via the Chrome task manager thankfully.
