Question

我试图使用Datatables和jquery填充我的表，但是我一直收到错误

TypeError: cannot use 'in' operator to search for 'length' in 'created_at'

在我的控制台中。

我的表：

＆＃13;

$(function () {
   $('.table-grid').DataTable({
       serverSide: true,
       processing: true,
       ajax: $('.table-grid').data('url'),
       columns: [
          'created_at',
          'username',
          'package_amount',
          'direct_id',
          'register_by',
          'action',
       ],
       responsive: true,
       searchDelay: 1000,
      });
    });

＆＃13;

<table class="table table-full table-full-small dt-responsive display nowrap table-grid" cellspacing="0" width="100%" role="grid" data-url="{{ route('admin.member.getList') }}">
                        <thead>
                        <tr>
                            <th data-id="created_at">Join Date</th>
                            <th data-id="username">Username</th>
                            <th data-id="package_amount">Package</th>
                            <th data-id="direct_id" data-orderable="false" data-searchable="false">Direct ID</th>
                            <th data-id="register_by">Registered By</th>
                            <th data-id="action" data-orderable="false" data-searchable="false">
                            Action
                            </th>
                        </tr>
                        </thead>
                <tbody>
                </tbody>
              </table>

＆＃13;

我使用的是JQuery 3.2.1 请帮忙！

注入网址的数据来自下面的函数

public function findAll (DataTables $dataTable, $table=false) {
    if (!$table) return $this->model->all();
    else {
        return $dataTable->eloquent($this->model->query())
            ->addColumn('action', function ($model) {
                return view('admin.member.action')->with('model', $model);
            })
            ->editColumn('direct', function ($model) {
                if ($direct = $model->direct()) return $direct->username;
                else return 'Member not found.';
            })
            ->editColumn('package_amount', function ($model) {
                return number_format($model->package_amount, 2);
            })
            ->make(true);
    }

$('.table-grid').DataTable({

Answer 2

升级时遇到的问题

未捕获的TypeError：无法使用'in'运算符来搜索'length'in

（写入时）升级到最新的数据表，例如：1.10.19。

由数据表修复：带有jquery-rails（4.3.3）的1.10.19

TypeError：不能使用＆＃39; in＆＃39;运营商搜索＆＃39;长度＆＃39;在＆＃39; created_at＆＃39;
