如果您的应用程序是一个iframe应用程序，fbml将不会被Facebook解析。所以你不能在iframe应用程序中使用fbml。在iframe应用程序中唯一可以使用的是XFMBL或serverfbml版本，它只支持fbml标签的一小部分。

请参阅此处和此处了解更多关于xfbml的详细信息，哪些标签是支持（fb：tabs is NOT）

所以我宁愿使用 jquery UI标签或类似的东西，如果我想要我的应用程序中的标签，可以自定义它以使Facebook看起来不错：）

I realize there is already a similar question, but there aren't any good answers. I looked all around the facebook developer app, and there isn't an automated way to do this. Please help!

If your app is an iframe app, fbml will NOT be parsed by facebook. So you can't use fbml in an iframe app. The only thing you can use in iframe apps is the XFMBL or serverfbml version which only supports a little subset of the fbml tags.

See here and here for more details on xfbml and which tags are supported (fb:tabs is NOT)

So I would rather use jquery UI tabs or something similar and customize it to have the facebook look'n'feel if I wanted tabs in my application :)
