Question

大家好下面Drupal 8 EventSubscriber类应该将drupalSettings附加到Drupal 8 javascript设置中。但不幸的是这个\ Drupal :: service（＆＃39;渲染器＆＃39;） - ＆gt; renderRoot（$ js_data）;没有附加drupal javascript设置。

namespace Drupal\ejectorseat\EventSubscriber;

use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Drupal\Core\Url;

class EjectorseatSubscriber implements EventSubscriberInterface {

  public function customEjector(GetResponseEvent $event) {
      $account = \Drupal::currentUser();
      $ejectorseat_interval = \Drupal::config('ejectorseat.settings')->get('ejectorseat_interval');
      if(empty($ejectorseat_interval)){
        $ejectorseat_interval = 60;
      }
      $ejectorseat_background = \Drupal::config('ejectorseat.settings')->get('ejectorseat_background');
      if(empty($ejectorseat_background)){
        $ejectorseat_background = 0;
      }

      if ($account->id() > 0 && (int) $ejectorseat_interval) {
          $js_data = array();
          $js_data['#attached']['drupalSettings']['ejectorSeat']['interval'] = $ejectorseat_interval;
          $js_data['#attached']['drupalSettings']['ejectorSeat']['url'] = Url::fromRoute('ejectorseat/check');
          $js_data['#attached']['drupalSettings']['ejectorSeat']['ignoreFocus'] = $ejectorseat_background ? TRUE : FALSE;
          \Drupal::service('renderer')->renderRoot($js_data);
      }
  }

  public static function getSubscribedEvents() {
    $events[KernelEvents::REQUEST][] = array('customEjector');
    return $events;
  }
}

我遇到了同样的问题，我没有找到OOP解决方案。在您的情况下，只需将您的逻辑形式的customEjector方法放在 ejectorseat.module 文件中名为 hook_js_settings_alter 的HOOK中。通过这种方式，您可以确保drupalSettings对象中的所有变量都可用。

仅供演示：

<?php
/**
 * Implements hook_js_settings_alter().
 *
 */
function ejectorseat_js_settings_alter(array &$settings,
    \Drupal\Core\Asset\AttachedAssetsInterface $assets
) {
     ...

      $settings['all_settings'] = $globalSettings->getAll();
      //if you want to push only a single value
      $settings['custom_link'] = $globalSettings->get('custom_link')
      $settings['ejectorSeat']['interval'] = $ejectorseat_interval;
      $settings['ejectorSeat']['url'] = Url::fromRoute('ejectorseat/check');
      $settings['ejectorSeat']['ejectorSeat']['ignoreFocus'] = $ejectorseat_background ? TRUE : FALSE;

 }

Drupal 8 #attached在eventsubscriber中没有工作
