I want to show an alert when users close popup

我想显示一个弹出(谷歌，Twitter等)，当用户关闭该对话框，我想显示一个警报"再见"，但警报没有出现:

<script>
var openDialog = function(uri, name, options, closeCallback) {
var win = window.open(uri, name, options);
var interval = window.setInterval(function() {
    try {
        if (win == null || win.closed) {
            window.clearInterval(interval);
            closeCallback(win);
        }
    }
    catch (e) {
    }
}, 1000);
return win;
};
var test = function() {
alert("bye");
};
openDialog("//google.com", "popup", "scrollbars=no", "test");
</script>

更改此代码

openDialog("//google.com", "popup", "scrollbars=no", "test");

与:

openDialog("//google.com", "popup", "scrollbars=no", test);

演示:http://jsfiddle.net/3on19uak/

这一行:

 openDialog("//google.com", "popup", "scrollbars=no", "test");

应该读:

 openDialog("//google.com", "popup", "scrollbars=no", test);

如果你愿意，你也可以这样做:

 openDialog("//google.com", "popup", "scrollbars=no", function(e){
    alert("bye");
 });
