尝试检测浏览器关闭事件

您是否尝试过此代码？

window.onbeforeunload = function (event) {    var message = 'important: Please click on 'Save' button to leave this page.';    if (typeof event == 'undefined') {        event = window.event;    }    if (event) {        event.returnValue = message;    }    return message;};$(function () {    $("a").not('#lnkLogOut').click(function () {        window.onbeforeunload = null;    });    $(".btn").click(function () {        window.onbeforeunload = null;});});

第二个功能是可选的，以避免在单击

#lnkLogOut

.btn
