推荐答案
尝试以异步方式加载JavaScript，请参阅： http://fbdevwiki.com/wiki/FB.init 或 http://developers.facebook.com/blog/post/530/ 的示例代码。
Try to load your javascript asychronously, see: http://fbdevwiki.com/wiki/FB.init or http://developers.facebook.com/blog/post/530/ for sample code.
此外，您的FB.Init（）缺少 oauth：true 和 appID： xxxx ，oauth 2.0是强制性的。让我们知道如果它有效
Also, your FB.Init() is missing oauth: true and appID: xxxx, oauth 2.0 is mandatory. Let us know if it works.
