在onbeforeunload之前确认

Question

我需要在用户离开页面之前提示用户，在确认时关闭选项卡，如果没有做任何事情。我想在onbeforeunload上发送一个ajax调用。

我唯一的想法是为这样的onunload和onbeforeunload编写处理程序：

window.onbeforeunload = function(){
    return 'Are you sure you want to leave?';
};
window.onunload = function(){
    $.get(
        "http://www.mysite.com/php/myhandler.php",
        { data: 1 }
    );
};

但这似乎不适用于jsFiddle

它在这个小提琴中工作得很好 - ＆gt; Perfectly working fiddle!!!

 function warning(){
            if(true){
                return "You are leaving the page";
                 $.ajax({
                        url: "test.php",
                        type: "post",
                        data: values to send
                        })
            }
        }
        window.onbeforeunload = warning;

Answer 2

只需将所有内容放在onbeforeunload

中

window.onbeforeunload = function(){
    $.get(
        "http://www.mysite.com/php/myhandler.php",
        { data: 1 }
    );
    return 'Are you sure you want to leave?';
};
