复制代码 代码如下:

<script language="javascript">

window.onbeforeunload = function () {

var n = window.event.screenX - window.screenLeft;

var b = n > document.documentElement.scrollWidth - 20;

if (b && window.event.clientY < 0 || window.event.altKey) {

try {

var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");

xmlhttp.open("POST", "LogOut.aspx", false);

xmlhttp.send();

//return true;

}

catch (e) {

alert('delete user account error message:' + e.message);

}

//return "你确定要退出系统吗？退出请按'离开此页'";

} else {

//alert("是刷新而非关闭");

}

}

</script>
