有什么方法可以检测用户是否按下了“留在页面上"?或“离开页面"在 beforeunload 事件中?

问题描述

我有什么方法可以在以下代码中检测到用户点击了离开页面"或留在页面上"按钮?

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?";
});

推荐答案

通过一些技巧，您至少可以确定用户是否留下.
如果用户离开了页面，那么您无能为力:

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?";
});
