Javascript is client side. And Session is server side.

So, using javascript you can't Logout from facebook. because facebook SDK's function sometimes doesn't terminate user session. So best practice is in your file put session_destroy() function if you want to destroy all the session variables or simply use print_r($_SESSION) and find out the session variables of facebook and unset those variable using unset($foo); if want to continue other session variable.
