    <script>
    function clearDefaultText(){
      var nickname = document.getElementById('nickname');

    public function hierarchicalauthority(){

     if(isset($_POST['liuyan']))
     {
      $data['nickname']=$_POST['nickname'];
      $data['content']=$_POST['content'];
      $data['email']=$_POST['email'];
      $data['status']=1;
      $data['replytime']=date('Y-m-d H:i:s',time());
      // print_r($data);die();
      $user=M('daili_liuyan_guestbook');
      $maxid=$user->max('id');
      $data['id']=$maxid+1;
      $user->add($data);


     // print_r($_POST);die();
     }
     $guestbook = D('daili_liuyan_guestbook')->select();
     $this->assign('guestbook',$guestbook);
     $this->display();
