我可以使用ajax从数据库加载数据并在编辑器中显示，但我不能编辑/保存这些数据。我用了CodeIgniter3

Question

$.ajax({

    url : "<?php echo base_url('admin/perusahaan_baik/edit_narasi_gcg')?>/" + id,
    type: "GET",
    dataType: "JSON",
    success: function(data)
    {

        $('[name="id"]').val(data.id);
        $('[name="posting_date"]').val(data.posting_date);
        $('[name="description"]').val(CKEDITOR.instances.description.setData(data.description));

$（'modal#u narasi'）。模态（'show'）；//完成加载$（'.modal title'）时显示引导模式。文本（“编辑Perusahaan Baik”）；//将标题设置为引导模式标题}，错误：函数（jqXHR，textStatus，errorshown）{alert（'error get data from ajax'）；}）；

    $data = array(

            'posting_date' => $this->input->post('posting_date'),
            'description' => $this->input->post('description')
        );

    $this->narasi_model->update_narasi_gcg(array('id' => $this->input->post('id')), $data);

    echo json_encode(array("status" => TRUE));

    public function get_by_id($id)
    {
        $this->db->from($this->table);
        $this->db->where('id',$id);
        $query = $this->db->get();

        return $query->row();
    }

    public function update_narasi_gcg($where, $data)
    {
        $this->db->update($this->table, $data, $where);
        return $this->db->affected_rows();  
    }

                    <div class="form-group">
                        <label class="control-label col-md-3">Posisi ID</label>
                        <div class="col-md-9">
                            <textarea name="description" id="description" rows="10" cols="80">

                      </textarea>
                        </div>
                    </div>

Answer 1

CKEDITOR.instances['description'].on('change',function(){
CKEDITOR.instances['description'].updateElement();
});

Answer 2

还添加id和posting_date

<div class="form-group">
<label class="control-label col-md-3">Posisi ID</label>
<div class="col-md-9">
<textarea name="description" id="description" rows="10" cols="80"></textarea>
<input type="hidden" name="posting_date" id="posting_date">
<input type="hidden" name="id" id="id">
</div>
</div>
