Javascript中，I＆QUOT能;重定向＆QUOT;用户onbeforeunload？如果不能，如何 [英] Javascript, Can I "redirect" user in onbeforeunload? If cant, how to

问题描述

是否有可能当用户关闭浏览器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的，不能正常工作

1. I tried onunload, does not work

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

我也试过另一种方法，它不工作之一：

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

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

＆LT;身体onbeforeunload =返回false; redirecty（）＆GT;

第三的方法，我想取消 onbeforeunload （指延时关闭浏览器）时，我称之为重定向功能， window.confirm ，如果是重定向，如果没有然后关闭浏览器。不过，这并不正常工作。

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.

有没有其他办法？也许提示，让用户选择是否重定向到新的页面时，他/她关闭浏览器？我跑出来的想法......

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

您onbeforeunload事件需要返回一个字符串（不等同于假），浏览器将包含此字符串显示给用户自己的消息。

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?";
    }

然而，这将是真正棘手的话你的信息的方式，用户将能够明白该怎么做。而且我不知道这是在每个浏览器功能强大，我只是尝试在浏览器，它的工作，但我结束了一个标签我不能收！我设法通过幸好Chrome的任务管理器将其杀死。

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.
