我想在服务器端做一些清理过程,我们保持上次注销时间。 To achieve this need fire an ajax call when the user clicks logout or the browser is closed.
为了实现这一点,需要在用户单击注销或浏览器关闭时触发 ajax 调用。 For IE the following code is working:
对于 IE,以下代码有效:
if (window.event.clientY < 0 && (window.event.clientX > (document.documentElement.clientWidth - 5) || window.event.clientX < 0)) {
logoutUser();//logging out the user
}
}
function logoutUser(){
var xmlhttp;
if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera,
//Safari
xmlhttp = new XMLHttpRequest();
} else {// code for IE6, IE5
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET", "Logout.action", true);
xmlhttp.send();
}

Use onbeforeunload
使用
onbeforeunload
window.onbeforeunload = function (e) {
e = e || window.event;
// For IE and Firefox prior to version 4
if (e) {
e.returnValue = 'Any string';
}
// For Safari
return 'Any string';
};
window.addEventListener('unload',fn,false);
var closedWindow = function() {
//code goes here
};
if (window.addEventListener) {
window.addEventListener('unload', closedWindow, false);
} else if (window.attachEvent) {
// pre IE9 browser
window.attachEvent('onunload', closedWindow);
}
