If user closed the web browser then automatically session history is erased, but I have to update it in my database whether user still in the session or not

推荐答案

在您的布局中，您应该使用Javascript，如下一个示例;

In your layout you should use Javascript like in the next example;

<script type="text/javascript">
        

        function onWindowClosing() {
            if (window.event.clientX < 0 || window.event.clientY < 0) {

.ajax（{
type：POST，
url：/ Account / OnWindowClosing
}）;
}
};

函数onKeydown（evt）{
if（evt！= undefined&& evt.altKey&& evt.keyCode == 115）// Alt + F4
{

.ajax({ type: "POST", url: "/Account/OnWindowClosing" }); } }; function onKeydown(evt) { if (evt != undefined && evt.altKey && evt.keyCode == 115) //Alt + F4 {

.ajax（{
type：POST，
url：/ Account / OnWindowClosing
}）;
}
};

window.onbeforeunload = onWindowClosing;
window.document.onkeydown = onKeydown;

< / script>

.ajax({ type: "POST", url: "/Account/OnWindowClosing" }); } }; window.onbeforeunload = onWindowClosing; window.document.onkeydown = onKeydown; </script>

然后在您的帐户控制器你必须实现方法 OnWindowClosing 来保存你想要的东西。



在我的下一篇文章中： MVC基本站点：第4步 - 使用AJAX，JSON在MVC 4.0中进行jqGrid集成， jQuery，LINQ和序列化 [ ^ ]我还提供了源代码，您可以看到上述事件的完整实现。尤其要看 _Layout.cshtml 布局页面和 AccountController 类。

Then in your Account controller you have to implement the method OnWindowClosing to save what you want.

In my next article: MVC Basic Site: Step 4 – jqGrid Integration in MVC 4.0 using AJAX, JSON, jQuery, LINQ, and Serialization[^] I have provided also source code, and you can see the complete implementation of the above events. Have a look especially on _Layout.cshtml layout page and on AccountController class.
