问题描述

我的用户表中有一个列,我想在时基上更新它,如果用户没有注销并关闭浏览器那么如何将状态从true更新为false请帮助找出解决方案。我正在使用c#linq。



希望得到积极回应



谢谢

解决方案

您可以在我的下一篇文章的源代码中找到此问题: MVC基本站点:步骤4 - 使用AJAX,JSON,jQuery,LINQ和序列化的MVC 4.0中的jqGrid集成[ ^ ]



您应该查看下一部分:



1.在 AccountController 方法 OnWindowClosing() onBeforeUnload onKeyDown 窗口事件调用,并用于做浏览器窗口关闭时的用户会话终结任务。



2.在主布局视图中 _Layout.cshtml 从底部开始的javscript部分文件:

函数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
});
}
};

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


I have a bit column in my users table, I want to update it on timing base, If user didn't logout and close the browser then how can I update the status from true to false please help to find out the solution. I am using c# linq.

hope for a positive response

Thanks

解决方案

You could find this problem solved in the source code of my next article: MVC Basic Site: Step 4 – jqGrid Integration in MVC 4.0 using AJAX, JSON, jQuery, LINQ, and Serialization[^]

You should look on the next parts:

1. In AccountController the method OnWindowClosing() that is invoked from onBeforeUnload and onKeyDown window events, and used to do user session finalization tasks when the browser window is closing.

2.In the main layout view _Layout.cshtml the javscript section from the bottom of the file:

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


.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;
