取消预扣取消确认 [英] catching beforeunload confirmation canceled?

问题描述

  window.onbeforunload = function（ e）{
 return你保存一些未保存的数据，你想离开吗？ 
} 
  

此提示可以通知用户，用户可以留在页面上或离开。但我想要更多地知道他是否离开，并且做他的决定的事情。我试过这个，

  window.onbeforunload = function（e）{
 var event = jQuery.Event（e） ; 
 var result = confirm（'想要离开'）; 
 if（result == false）{
 // do sth .. 
 event.preventDefault（）; 
} else {
 //清理
} 
} 
  

但它失败了！它总是消失！

任何身体都可以帮助我做这个吗？

解决方案

您使用的方法（防止事件冒泡）有意无法进行，否则可能会阻止用户离开您的页面

您可以通过执行清理 onunload 来实现与您想要的相似的东西，并执行您始终执行的操作想做 onbeforeunload 。

I want to do some stuff when user is leaving a page, I add this code

window.onbeforunload = function (e){
   return "You save some unsaved data, Do you want to leave?";
}  

This prompt can notify the user and user can stay on the page or leave. But I want more to know whether he leaves or not, and do thing on his decision. I tried this,

window.onbeforunload = function (e){
   var event = jQuery.Event(e);
   var result = confirm('want to leave?');
   if (result ==  false){
     //do sth.. 
     event.preventDefault();
   }else{
    //do clean up
   }
} 

But it fails!! It always goes away!

Can any body help me doing this?

解决方案

The method you use (preventing bubbling of the event) is intentionally not possible, otherwise you could prevent users from leaving your page.

You can achieve something similar to what you want by doing your cleanup onunload, and do the stuff you always want to do onbeforeunload.
