Javascript 检测浏览器或选项卡关闭
是否有跨浏览器JavaScript/jQuery代码来检测浏览器或浏览器选项卡是否正在关闭,而不是由于单击了链接吗?如果我没有弄错,您想知道选项卡/窗口何时有效关闭。好吧,在Javascript 检测浏览器或选项卡关闭,javascript,jquery,Javascript,Jquery,是否有跨浏览器JavaScript/jQuery代码来检测浏览器或浏览器选项卡是否正在关闭,而不是由于单击了链接吗?如果我没有弄错,您想知道选项卡/窗口何时有效关闭。好吧,在Javascript中检测此类内容的唯一方法是onunload和onbeforeuload事件 不幸的是(或幸运的是?),当您通过链接或浏览器后退按钮离开站点时,也会触发这些事件。因此,这是我能给出的最好答案,我认为您无法在Javascript中检测到纯close。如果我错了,请纠正我。 <body onbeforeu

<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') ;
}
}
var myclose=false;
函数ConfirmClose()
{
如果(event.clientY<0)
{
event.returnValue='您已关闭浏览器。是否要从应用程序注销?';
setTimeout('myclose=false',10);
myclose=true;
}
}
函数HandleOnClose()
{
如果(myclose==true)
{
//注销时使会话无效的注销页面的url
替换('/contextpath/j_-spring_-security_-logout');
}
}
//这在IE7中起作用,如果您要关闭只有一个选项卡的选项卡或浏览器
$(window).unload( function () { alert("Bye now!"); } );
由于某些原因,基于Webkit的浏览器不符合对话框的规范。一个几乎相互交叉的例子与下面的例子很接近
window.addEventListener("beforeunload", function (e) {
var confirmationMessage = "\o/";
(e || window.event).returnValue = confirmationMessage; //Gecko + IE
return confirmationMessage; //Webkit, Safari, Chrome
});
此示例用于处理所有浏览器。试试这个,
我相信这对你会有用的
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type='text/javascript'>
$(function() {
try{
opera.setOverrideHistoryNavigationMode('compatible');
history.navigationMode = 'compatible';
}catch(e){}
function ReturnMessage()
{
return "wait";
}
function UnBindWindow()
{
$(window).unbind('beforeunload', ReturnMessage);
}
$(window).bind('beforeunload',ReturnMessage );
});
</script>
$(函数(){
试一试{
opera.setOverrideHistoryNavigationMode(“兼容”);
history.navigationMode='compatible';
}捕获(e){}
函数ReturnMessage()
{
返回“等待”;
}
函数UnBindWindow()
{
$(窗口).unbind('beforeunload',ReturnMessage);
}
$(window.bind('beforeunload',ReturnMessage));
});
简单解决方案
window.onbeforeunload = function () {
return "Do you really want to close?";
};
很抱歉,我无法向现有答案之一添加注释,但如果您想实现一种警告对话框,我只想指出,任何事件处理程序函数都有一个参数-事件。在您的情况下,可以调用event.preventDefault()来禁止自动离开页面,然后发出您自己的对话框。我认为这比使用标准的丑陋和不安全的警报()更好。我个人基于kendoWindow对象(Telerik的Kendo UI,除了kendoGrid和kendoEditor之外,它几乎是完全开源的)实现了我自己的一组对话框。您还可以使用jQuery UI中的对话框。不过请注意,这些事情是异步的,您需要将一个处理程序绑定到每个按钮的onclick事件,但这一切都很容易实现
然而,我同意缺少真正的关闭事件是可怕的:例如,如果您只想在真正关闭的情况下重置后端的会话状态,这是一个问题
window.onbeforeunload = function ()
{
if (isProcess > 0)
{
return true;
}
else
{
//do something
}
};
如果您在浏览器中的任何进程中关闭窗口或刷新页面,此函数将显示一个确认对话框。此函数适用于所有浏览器。您必须在ajax进程中设置isProcess var。尝试此操作。它会起作用的。不支持jquery卸载方法
window.onbeforeunload = function(event) {
event.returnValue = "Write something clever here..";
};
没有事件,但有一个属性window.closed
,在撰写本文时,所有主要浏览器都支持该属性。因此,如果您确实需要知道,您可以轮询窗口以检查该属性
if(myWindow.closed){do things}
注:
轮询任何内容通常都不是最佳解决方案。如果可能的话,应该使用窗口.onbeforeunload
事件,唯一的警告是,如果您导航到其他链接,它也会触发。我需要在浏览器或选项卡关闭时自动注销用户,而不是在用户导航到其他链接时。我也不希望在发生这种情况时显示确认提示。经过一段时间的努力,特别是在IE和Edge上,以下是我在基于IE的方法之后所做的事情(检查使用IE 11、Edge、Chrome和Firefox)
window.addEventListener("beforeunload", function (e) {
var confirmationMessage = "tab close";
(e || window.event).returnValue = confirmationMessage; //Gecko + IE
sendkeylog(confirmationMessage);
return confirmationMessage; //Webkit, Safari, Chrome etc.
});
首先,在JS中的beforeunload
事件处理程序中启动服务器上的倒计时。ajax调用需要同步,IE和Edge才能正常工作。您还需要使用return代码>防止确认对话框显示如下:
window.addEventListener("beforeunload", function (e) {
$.ajax({
type: "POST",
url: startTimerUrl,
async: false
});
return;
});
<body onUnload="LogOff()">
启动计时器将cancelLogout
标志设置为false。如果用户刷新页面或导航到另一个内部链接,服务器上的cancelLogout
标志将设置为true。计时器事件结束后,它将检查cancelLogout
标志,查看注销事件是否已取消。如果计时器已取消,则会停止计时器。如果浏览器或选项卡已关闭,则cancelLogout
标志将保持为false,事件处理程序将注销用户
实现说明:我正在使用ASP.NET MVC 5,我正在用一个被覆盖的控制器.OnActionExecuted()
方法取消注销。我找到了一种方法,可以在我的所有浏览器上运行
在以下版本上测试:
Firefox 57,Internet Explorer 11,Edge 41,最新的Chrome浏览器之一(不会显示我的版本)
注意:如果您以任何可能的方式离开页面(刷新、关闭浏览器、重定向、链接、提交…),onbeforeunload将触发。如果您只希望它发生在浏览器关闭时,只需绑定事件处理程序即可
对于类似的任务,您可以使用sessionStorage
在本地存储数据,直到关闭浏览器选项卡
sessionStorage
对象仅存储一个会话的数据(当浏览器选项卡关闭时,数据将被删除)。()
