浏览器在asp.net中关闭之前保存数据 [英] Save data before browser closed in asp.net

问题描述

我要求我必须检测浏览器关闭以及浏览器选项卡关闭。



如果用户点击浏览器关闭按钮或尝试关闭然后我应该显示一个对话框（有2个按钮退出并取消）你真的想退出吗？如果用户点击退出，则保存其工作数据并关闭浏览器。



谢谢

这里应该是javascript或jquery。在服务器端检测很困难（但我认为有一些可能的解决方案）。 Bcoz在处理您的请求时，用户可能已经关闭了该选项卡。所以要避免使用javascript更好，因为它可以轻松检测到用户活动。

Check the following link

Browser/tab close detection using javascript (or any other language)[^]

Here this should be either a javascript or an jquery. It''s difficult(but I think there are some possible solutions) to detect on the server side. Bcoz while the time your request is processed , the user might already closed the tab. So to avoid that it is better to use javascript as it could detect the user activity easily.

按照文章 - 在浏览器关闭时或退出页面时保存更改 [ ^ ]。 />


您需要使用 window.onbeforeunload [ ^ ]事件。

Follow the article - Save Changes on Close of Browser or When Exiting the Page[^].

You need to use window.onbeforeunload[^] event.

window.onbeforeunload = check;

function check() {
    var response = confirm("Are you sure you want to exit this page?";
    
    if(response == true)
    {
        // Do what ever you want to do. Call function to save data.
    }
}

参考 - 关于浏览器关闭的Asp.net会话 [ ^ ]了解如何通过调用Web服务将数据存储在浏览器上。

Refer - Asp.net session on browser close[^] to know how it stores data on browser close by calling a web service.
