Question

我正在尝试使用dataTable通过CodeIgniter管理我的数据。

dataTable加载良好，但是当我使用搜索时，它花费很长时间并加载所有数据并发送一个对象（如下图所示）以起作用。

这是我的JavaScript代码：

<script type="text/javascript">
            jQuery(document).ready(function () {
                var table=jQuery('#table-3').dataTable({
                    "sPaginationType": "bootstrap",
                    "aLengthMenu": [[10, 25, 50, -1], [10, 25, 50, "All"]],
                    "bStateSave": true,
                    "processing": true,
                    "serverSide": true,
                    "ajax":{
                     "url": "<?php echo base_url('index/jsonForDbTableMain') ?>",
                     "dataType": "json",
                     "type": "POST",
                     "data":{  '<?php echo $this->security->get_csrf_token_name(); ?>' : '<?php echo $this->security->get_csrf_hash(); ?>' }
                                   },
                "columns": [
                          { "data": "id" },
                          { "data": "name" },
                          { "data": "clId" },
                          { "data": "itNum" },
                          { "data": "eType" },
                          { "data": "fs" },
                       ],

                                   "columnDefs": [
                                        {
                                            "targets": [ 0 ], //first column / numbering column
                                            "orderable": false, //set not orderable
                                        },],
                });
                table.columnFilter({
                    "sPlaceHolder" : "head:after"
                });
            });
        </script>

        $columns = array( 
                            0 =>'id',

            {

                $nestedData['id'] = $pro->id;
                $nestedData['name'] = $pro->name;
                $nestedData['clId'] = $pro->clId;
                $nestedData['itNum'] = $pro->itNum;
                $nestedData['eType'] = $pro->eType;
                $nestedData['fs'] = $pro->fs;

                $data[] = $nestedData;

            }
        }

        $json_data = array(
                    "draw"            => intval($this->input->post('draw')+1),  
                    "recordsTotal"    => intval($totalData),  
                    "recordsFiltered" => intval($totalFiltered), 
                    "data"            => $data   
                    );

        echo json_encode($json_data);
        exit();
    }

我的问题是：如何通过CodeIgniter在dataTable中进行搜索？

DataTable在搜索字段时发送对象对象
