2. 5 fb.module \fb_add_js()

Helper function for FBJS files.

Useful for adding Facebook Javascript, which will be incorporated into canvas pages or profile boxes. When included this way, javascript must be embedded inline, rather than refer to an external URL. So this function will actually read a local file and include the contents inline.

      'fbjs' => array(

      // Refresh facebook's cache when file changes
      $filename .= "?v=" . filemtime($filename);
    }

    // 'post_settings' is a hack to make our code come after settings. This is
    // ugly, but we're doing it because there is no "onready" in FBJS.
    drupal_add_js($filename, 'post_settings', 'fbml');
    $cache[$filename] = TRUE;
