Question

我正在开发CodeIgniter项目。在项目中我使用的是JQgrid表。我想使用JQgrid显示数据。我从数据库中获取数据，但是我无法在JQgrid中显示数据，但我可以在TextArea中显示数据。

模型文件

public function getmodeldata()
{
    $query=$this->db->get('model');
    $data = json_encode($query->result());
    return $data;
}

控制器文件

public function model()
{
  $data['brand']=$this->Admin_model->getbranddata();
  $data['getmodel']=$this->Admin_model->getmodeldata();
  $this->load->view('layouts/header');
  $this->load->view('Admin/model',$data);
  $this->load->view('layouts/footer');
}

查看文件

<textarea id="data"><?php echo $getmodel?></textarea>

如果您的数据与json字符串一样，则需要替换

data: grid_data,
datatype: "json",

带

datastr: grid_data,
datatype: "jsonstring",

在Codeigniter中{J 44grid中显示动态数据
