我试图发布到 facebook 新闻源，但弹出框不时出现。我认为这与回发或其他事情有关。这是发生了什么：用户再见并在弹出窗口中发送到 Payson（payson 是瑞典版的 Paypal），然后 payson 将用户发送回我的页面，仍然在弹出窗口中。这是一个运行的代码：
function postToFeed() {
try {
FB.getLoginStatus(function (response) {
if (response.status === 'connected') {
var obj = {
method: 'feed',
link: 'link',
picture: 'imagelink',
name: 'title',
caption: 'some text...',
description: 'some text...',
redirect_uri: 'url'
};
function callback(response) {
document.getElementById('msg').innerHTML = "Post ID: " + response['post_id'];
}
FB.ui(obj, callback);
}
else {
alert("not connected")
}
});
} catch (e) {
alert(e.Message)
}
}
现在发生的事情是我从我的 try catch 中得到了错误，它只是说FB is not defined。
如果我之后使用按钮运行此功能，它就可以正常工作。如果我从 payson 伪造回发，它也可以工作，但如果我在新窗口中进行，则不会。
我试图将 FB.init 函数放入我的函数中，但这没有帮助。
谢谢你的帮助！
