如何使用ASP.NET检测页面关闭事件

I have a ASP.NET web app with a MasterPage and contents page, from the MasterPage when I click a MenuItem to open a new aspx Page. if I want to close the new page browser tab, I want to show a popup or a dialog that alert the user that he is closing the browser tab. I dont know how to detect the close browserTab button. I used the following code in the new aspx page:

当我单击MenuItem打开一个新的aspx页面时,我有一个带有MasterPage和内容页面的ASP.NET Web应用程序。如果我想关闭新的页面浏览器选项卡,我想显示一个弹出窗口或一个对话框,提醒用户他正在关闭浏览器选项卡。我不知道如何检测关闭browserTab按钮。我在新的aspx页面中使用了以下代码:

<script type="text/javascript">
    function CloseWindow() {
        alert('closing');
        window.close();
    }
</script>

new page code behind:

新页面代码背后:

protected void Page_Load(object sender, EventArgs e)
{
    Page.ClientScript.RegisterOnSubmitStatement(typeof(Page), "closePage", "window.onunload = CloseWindow();");
}

Thanx in Advantage.

This works perfect.

这很完美。

javascript detect browser close tab/close browser

javascript检测浏览器关闭选项卡/关闭浏览器

<body onbeforeunload="ConfirmClose()" onunload="HandleOnClose()">

var myclose = false;

function ConfirmClose()
{
    if (event.clientY < 0)
    {
        event.returnValue = 'You have closed the browser. Do you want to logout from your application?';
        setTimeout('myclose=false',10);
        myclose=true;
    }
}

function HandleOnClose()
{
    if (myclose==true) 
    {
        //the url of your logout page which invalidate session on logout 
        location.replace('/contextpath/j_spring_security_logout') ;
    }   
}

I had a lot of problems with this myself and the only thing that works is: "window.onbeforeunload" event from javascripts but the problem is this gets executed a lot more than when you'd expect. So basicly if your working with a master page etc I don't think it can be done.

我自己遇到了很多问题,唯一有效的是:来自javascripts的“window.onbeforeunload”事件,但问题是这比你期望的要多得多。所以基本上如果你使用母版页等我不认为可以做到。

I think it's best you try to approach this differently because else your closing message will show up to often.

我认为你尝试以不同的方式处理这种情况是最好的,因为否则你的结束信息会经常出现。

You can handle this with javascript in your page.
First create a function:

您可以在页面中使用javascript处理此问题。首先创建一个函数:

function closeMessage() {
    return "Are you sure you want to leave this page";
}

After that assign this method:

之后,分配此方法:

window.onbeforeunload = closeMessage;

Please let me know if was helpfull

You need to catch the event for closing the browser and use it to do whatever you wanna do. Here is the code that worked for me.

您需要捕获事件以关闭浏览器并使用它来做您想做的任何事情。这是适合我的代码。

        <script type="text/javascript">
          window.onbeforeunload = function (e) {
               var e = e || window.event;
               if (e) e.returnValue = 'Browser is being closed, is it okay?';//for IE & Firefox
               return 'Browser is being closed, is it okay?';// for Safari and Chrome
           };
        </script>

Hope this helps..

If I get you correctly, you want to know when a tab/window is effectively closed. Well, afaik your only way in Javascript to detect that kind of stuff are onunload & onbeforeunload events. Those events are also fired when you leave a site over a link or your browsers back button. So this is the best answer I can give, I don't think you can natively detect a pure close in Javascript. Correct me if I'm wrong here.you can go through browser-tab-close-detection-using-javascript-or-any-other-language

如果我找到你,你想知道什么时候选项卡/窗口有效关闭。好吧,afaik你在Javascript中唯一的方法来检测那种东西是onunload和onbeforeunload事件。当您通过链接或浏览器返回按钮离开网站时,也会触发这些事件。所以这是我能给出的最好的答案,我不认为你可以在Javascript中原生地检测到纯粹的关闭。如果我在这里错了,请纠正我。你可以通过浏览器选项卡关闭检测 - 使用-javascript或任何其他语言
