function fb_connect_init_js in Drupal for Facebook 6.2

Add javascript to a facebook connect page.

Use this to add calls to facebook JS, http://wiki.developers.facebook.com/index.php/JS_API_Index.

We use Drupal's cache to store the javascript until it is rendered to a page. This approach is analogous to drupal_set_message storing data temporarily in the session. We use cache instead of session, because the session is not shared between Facebook's event callbacks and regular page requests.
