Notes
Using the condition Attribute
All XFBML tags support the condition attribute. This attribute determines whether an XFBML element is visible or hidden. When condition is absent, the element is visible by default. The value of condition should be a string containing some JavaScript code. The JavaScript should be evaluated into either a boolean or an FB.Waitable object whose result field is a boolean. The FB.Waitable object is designed to allow asynchronous evaluation. For example, if you want to specify an element should be visible only if the current users can see the profile of another user, you can use this markup:
The following are some pre-built condition objects.
Rendering Issues
If you're having problems trying to get this form to render, try making a link that the user can click with this onclick handler:
FB.Connect.inviteConnectUsers();
That should render the Connect form in an FBML popup for you.
