Laravel：我在控制器中写的 URL 在视图中不起作用

Question

我在 Controller 中写了 url 链接并通过它json_encode，当然在我转义单引号之后......

当我单击 url 链接时，它将不起作用，它将显示：

网址将如下所示：

http://localhost/BSProject/public/%7B%7B%20URL::to ('schedule/24/edit')

所以这里是链接控制器

  public function liveSearch(Request $request)

{

    if($request->ajax())

    {

        $output = '';

        $query = $request->get('query');

        if($query != '')

        {

            $data = DB::table('schedules')

                ->where('schedule_number', 'like', '%'.$query.'%')

                ->orWhere('route_name', 'like', '%'.$query.'%')

                ->orWhere('user_first', 'like', '%'.$query.'%')

                ->orWhere('id', 'like', '%'.$query.'%')

                ->get();

        }

        else

        {

            $data = DB::table('schedules')

                ->get();

        }

        $total_row = $data->count();

        if($total_row > 0)

        {

            foreach($data as $row)

            {

                $output .= '

                    <tr>

                        <td>'.$row->id.'</td>

                        <td>'.$row->schedule_number.'</td>

                        <td>'.$row->route_name.'</td>

                        <td>'.$row->user_first.'</td>

                        <td>'.$row->created_at.'</td>

                        <td> <a style="margin-left: 5em; " href="{{ URL::to(\'schedule/' .$row->id .'/edit\')">

                            <button style=" font-size: 1em; width: 4.5em; height: 2.5em;"  type="button" class="btn btn-success btn-sm">Edit

                            </button>

                        </a>

                    </tr>

                ';

            }

        }

        else

        {

            $output = '

                <p>

                    No Schedule Lists found

                </p>

            ';

        }

        echo json_encode($output);

    }

}

Answer 1

错误在这里：（使用刀片语法并将其直接传递给客户端）$output .= '&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <tr>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <td>'.$row->id.'</td>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <td>'.$row->schedule_number.'</td>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <td>'.$row->route_name.'</td>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <td>'.$row->user_first.'</td>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <td>'.$row->created_at.'</td>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <td> <a style="margin-left: 5em; " href="{{ URL::to(\'schedule/' .$row->id .'/edit\')">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <button style=" font-size: 1em; width: 4.5em; height: 2.5em;"&nbsp; type="button" class="btn btn-success btn-sm">Edit&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </button>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </a>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </tr>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ';像这样使用它：$output .= '&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <tr>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <td>'.$row->id.'</td>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <td>'.$row->schedule_number.'</td>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <td>'.$row->route_name.'</td>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <td>'.$row->user_first.'</td>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <td>'.$row->created_at.'</td>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <td> <a style="margin-left: 5em; " href="' . url('schedule/' .$row->id .'/edit') .
