javascript - 我想在用户关闭弹出窗口时显示警报

Question

我想显示一个弹出窗口(Google、Twitter 等)，当用户关闭该对话框时，我想显示一个警报“再见”，但该警报不会出现:

<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>

Answer 1

更改此代码

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

这样:

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