錯誤在yii2上使用pjax

我想通過yii2上的pjax實現內容自動載入，但是我得到Uncaught TypeError：jQuery（...）。pjax不是函數。我無法解決它。這是我的看法文件：錯誤在yii2上使用pjax

這是行動Sitecontroller：

public function actionInner($action = '', $a = 0) 
    { 
     $posts = Event::find()->limit(5 + $a*3)->all(); 
foreach ($posts as $post) { 
      $post->price = $post->price - $post->price * $post->discount/100; 
     } 
     if ($action === 'name') { 
      $posts = Event::find()->limit(5 + $a*3)->orderBy(['title' => SORT_ASC])->all(); 
     foreach ($posts as $post) { 
      $post->price = $post->price - $post->price * $post->discount/100; 
     } 
      } 
     $news = Event::find()->limit(5 + $a*3)->orderBy(['date' => SORT_DESC])->all(); 
     $populars = Event::find()->where(['is_popular'=> 1])->limit(5 + $a*3)->orderBy(['likes' => SORT_DESC])->all(); 

     return $this->render('inner',[ 
      'posts' => $posts, 
      'time' => date('H:i:s'), 
      'a' => $a, 
      'action' => $action 
     ]); 
    }
