有没有办法检测用户是否按下“留在页面”或“离开页面”在beforeunload事件？ [英] Is there any way to detect if user pressed "Stay on page" or "Leave page" in beforeunload event?

问题描述

 
有什么方法可以在以下代码中检测到：用户点击离开页面或留在页面按钮？ code> $（window）.on（'beforeunload'，function（）{
 return你保存一些未保存的数据，你想离开吗？; 
}）; 
  

解决方案

使用几个黑客，至少可以确定用户停留了。

如果用户离开了网页，您可以做的不多：

  var timeout; 
 
 $（window）.on（'beforeunload'，function（）{
 timeout = setTimeout（function（）{
 // user stayed，do stuff here 
}，1000）; 
返回您保存一些未保存的数据，是否要离开？; 
}）; 
  

FIDDLE

Is there any way that I could detect in the following code that either user clicked "leave page" or "stay on page" button ?

$(window).on('beforeunload', function (){
    return "You save some unsaved data, Do you want to leave?";
});

解决方案

With a few hacks you can at least determine if the user stayed.
If the user left the page, there's not much you can do about that :

var timeout;

$(window).on('beforeunload', function (){
    timeout = setTimeout(function() {
        // user stayed, do stuff here
    }, 1000);
    return "You save some unsaved data, Do you want to leave?";
});
