      if ($path != $_GET['q']) {
        $page_match = $page_match || drupal_match_path($_GET['q'], $js_rule['rule_conditions']);
      }

      // When $js_rule['rule_type'] has a value of 0, the rule is matched on
      // all pages except those listed in $js_rule['rule_conditions'].
      // When set to 1, it is displayed only on those pages listed in
      // $js_rule['rule_type'].
