在浏览器关闭之前关闭 - 如何查找用户是否选择“保持”或“离开” [英] On browser close beforeunload - how to find if user selected "Stay" or "Leave"

问题描述

为了让事情变得非常简单 - 我有以下代码：

 
 $（window）.bind（beforeunload，function（event ）{b $ b return''; 
}）
 

至少在Chrome，FireFox和IE9上 - 当用户关闭时浏览器 - 他有两个选择 - 留在页面上或离开此页面（该消息因浏览器而异）

现在我怎么找到用户选择什么选项
为简单起见 - 可以说 - 我想根据用户选择的选项显示额外的消息。

类似于 - 只是为了给出一个想法

 
 if（option ==Stay on Page）
 alert（谢谢你继续留下）; 
 if（选项==离开此页面）
 alert（对不起，你决定出发 - 请马上回来）; 
 

我如何捕捉 - 用户选择了什么。
非常感谢

解决方案

据我所知，出于安全原因，您不允许这样做。您可以做的唯一事情是：

  window.onbeforeunload = function（）{
 return'您的确认信息'; 
} 
  

To keep things very simple - I have the following code

$(window).bind("beforeunload",function(event) {
    return '';
})

Atleast on Chrome,FireFox and IE9 - when a user closes the browser - he is presented with two options - "Stay on Page" or "Leave this Page" (The message varies from browser to browser)

Now how can I find out what option the user selected For sake of simplicity - lets say - I want to show an extra message based on which option the user selected

Something like - just to give an idea

if(option=="Stay on Page")
   alert("Thanks for continuing to stay");
if(option=="Leave this page")
   alert("Sorry you decided to go - please come back soon");

How do I capture - what the user selected. Thanks much

解决方案

As far as I know, you are not allowed to do that, for security reasons. The only thing you can do is the below:

window.onbeforeunload = function(){
    return 'Your confirmation message';
}
