关闭浏览器/选项卡时调用我的注销功能

Question

在我的应用程序我必须在关闭标签或浏览器时强行注销用户。我有注销功能，我想在用户关闭标签/浏览器时调用它。我试过这块代码，但它不适合我

<script type="text/javascript">
        $(function () {
            $(window).bind("beforeunload", function () {
                fnLogOut();
            })
        });
        function fnLogOut() { alert('browser closing'); }
 </script>

任何帮助？

＆＃13;

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;
});
});
