jQuery parse HTML

as far as i understand, your jquery script was ment to do a live search from a database.
i think, you don-t need id.

did you try the following:
controller:

public function view($id = null)
    {
        $article = $this->Articles->get($id, [
            'contain' => ['Users', 'Comments', 'Tags']
        ]);
		$parsearticle = $this->Articles->find()->extract('Isi');


        $this->set('article', $parseartice);
    }

in view:

<php echo h($article); ?>
