如何在Laravel中重新加载datatables数据？

Question

我正在使用Laravel 5.6和datatables插件1.10.18。我从mikrotik获得了数据。我想每5秒重新加载一次数据。但是出错了。

我的pppoeClientConnected控制器

public function pppoeClientConnected()
    {
        $server = Server::find(1);
        $con = Roar::connect($server->server_ip, $server->server_port,$server->username,$server->password);
        if($con->isConnected()){
            $active_users = new Active($con);
            $users = $active_users->getAll();
        } else {
            Session::flash('message', 'Not Connected!');
            Session::flash('m-class', 'alert-danger');
            return redirect()->route('client.index');
        }


        return view("admin.pages.client_pppoe_connected", [
            'clientData' => $users,
            'page_title' => 'PPPoE Connected Client',
        ]);
    }

我的admin.pages.client_pppoe_connected刀片页面

                    <thead>
                    <tr>
                        <th style="display: none" class="hidden-print"></th>
                        <th>#</th>
                        <th>Client Name</th>
                        <th>Username</th>
                        <th>Mac Address</th>
                        <th>Connected IP</th>
                        <th>Connected Time</th>
                    </tr>
                    </thead>

                    <tbody>
                    @php($i = 0)
                    @foreach ($clientData as $dataClient)
                    @php($i = $i+1)
                    @php($client = \App\Client::where('username', $dataClient['name'])->first())
                    @if($dataClient['name'] == $client['username'])
                    <tr>
                    <td style="display: none" class="hidden-print">{{ $dataClient['.id'] }}</td>
                    <td>{{ $i }}</td>
                    <td>{{ $client['client_name'] }}</td>
                    <td>{{ $dataClient['name'] }}</td>
                    <td>{{ $dataClient['caller-id'] }}</td>
                    <td>{{ $dataClient['address'] }}</td>
                    <td>{{ $dataClient['uptime'] }}</td>
                    </tr>
                    @endif
                    @endforeach


                    </tbody>

脚本

$(document).ready(function () {

            var table = $('#datatables').DataTable({
                    pagingType: "full_numbers",
                    columnDefs: [{orderable: false, targets: [4]}]

                });

            setInterval(table.ajax.reload, 5000);

        });

我收到此错误。
