Question

我想要显示一个弹出窗口（Google，Twitter等），当用户关闭该对话框时，我想要显示警告＆＃34; bye＆＃34;，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");

与此：

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

Answer 2

这一行：

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

应阅读：

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

如果你想要，你也可以这样做：

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

我想在用户关闭弹出窗口时显示警告
