I had this same problem but couldn't find any sample code. Anyways, I came up with this, which works for me. Hope this helps someone.

FB.api('/me/permissions', function (response) {
            var perms = response.data[0];

            if (perms.publish_stream) {                
                // User has permission
            } else {                
                // User DOESN'T have permission
            }                                            
    } );

Looks like is not supported. At least is not documented.

You may read from javascript once the permission is granted though.

The API method you're looking for is Users.hasAppPermission. You could call it directly from JavaScript, but it will probably be more efficient to write your own HTTP method, that calls it via API and returns "true" or "false" via JSON.

There is also a filed bug (13378) that Users.hasAppPermission has no Graph API equivalent.

In the new Graph API (including via JavaScript) this can be accomplished by accessing "/[user]/permissions".

From the User object documentation:

permissions

The permissions that user has granted the application.

array containing a single object which has the keys as the permission names and the values as the permission values (1/0) - Permissions with value 0 are omitted from the object by default; also includes a type field which is always permissions.
