Question

我对ajax和json相当陌生，非常感谢您的帮助。我正在对Laravel控制器进行Ajax调用，以从称为“主题”的数据库表中返回一些字段，并将其显示在Laravel视图的数据表中。问题是，当我打开视图时，看到的是JSON而不是数据表。

以下是查看主题/索引中返回的内容：

{"draw":0,"recordsTotal":8,"recordsFiltered":8,"data":[{"id":"1","name":"Biology"},{"id":"3","name":"English Language"},{"id":"4","name":"Physics"},{"id":"5","name":"Chemistry"},{"id":"6","name":"Mathematics"},{"id":"7","name":"Mathematics"},{"id":"8","name":"English Language"},{"id":"9","name":"French"}],"queries":[{"query":"select count(*) as aggregate from (select '1' as `row_count` from `subjects`) count_row_table","bindings":[],"time":4.65},{"query":"select `id`, `name` from `subjects`","bindings":[],"time":0.41}],"input":[]}

这是视图/ subjects / index中的HTML

<table id="subjects_table" class="table table-bordered" style="width:100%">
    <thead>
            <tr>
                <th>Id</th>
                <th>Subject</th>
            </tr>
                </thead>
                <tbody>

                </tbody>
        </table>

这是Laravel控制器中的代码：

class SubjectsController extends Controller
{
    public function index()
    {
        $subjects = Subject::select('id', 'name');
        return Datatables::of($subjects)->make(true);
   }
}

以下是进行Ajax调用的代码：

$('#subjects_table').DataTable({
      "processing": true,
      "serverSide": true,
      "ajax": "{{route('subjects.index')}}",
      "columns":[
          {"data": "id"},
          {"data": "name"}
      ]
});

以下是web.php中的路由定义：

Route::get('subjects/', 'SubjectsController@index')->name('subjects.index');

我们将不胜感激

您应该尝试以下操作：

路线

Route::get('subjects', 'SubjectsController@index')->name('subjects.index');
Route::get('getsubjects', 'SubjectsController@getSubjects')->name('subjects.get');

SubjectsController

class SubjectsController extends Controller
{
    public function index()
    {
        return view('subjects.index');
        $subjects = Subject::select('id', 'name');
        return Datatables::of($subjects)->make(true);
   }

   public function getSubjects()
    {

        return \DataTables::of(Subject::query())->make(true);

   }
}

查看

    <table id="subjects_table" class="table table-bordered" style="width:100%">
    <thead>
            <tr>
                <th>Id</th>
                <th>Subject</th>
            </tr>
                </thead>
                <tbody>

                </tbody>
        </table>

<script src="https://cdn.datatables.net/1.10.12/js/jquery.dataTables.min.js"></script>
    <script type="text/javascript">
    $(document).ready(function() {
        $('#subjects_table').DataTable({
            processing: true,
            serverSide: true,
            ajax: '{{ route('subjects.get') }}',
            columns: [
                {data: 'id', name: 'id'},
                {data: 'name', name: 'name'},
                {data: 'email', name: 'email'},
            ]
        });
    });
    </script>

在对Laravel Controller进行Ajax调用后，显示的是JSON，而不是数据表
