Datatables 我的数据库数据不是'；t显示在jQuery数据表中

我想在中显示数据库中的数据，但它不显示数据。它只是显示了我在下面发布的一个简单列表，我尝试了太多的东西，我发现了一些相关的问题，但它们是用PHP编写的，我不理解，因为我对PHP一无所知

Jquery ajax：

$(document).ready(function () {
    $("#demoGrid").DataTable({
        "processing": true,
        "serverSide": true,
        "info": true,
        "stateSave": true,
        "lengthMenu": [[10, 20, 50, -1], [10, 20, 50, "All"]],
        "ajax": {
            "url": "/Login/Display",
            "type": "GET"
        },
        "columns": [
            { "data": "EmployeeId", "orderable": true },
            { "data": "Name", "orderable": true },
            { "data": "Position", "orderable": true },
            { "data": "Office", "orderable": true },
            { "data": "Salary", "orderable": true },
        ],
        "order": [[0, "asc"]]
    });
});

public ActionResult Display()
        {
            List<Empdetail> list = new List<Empdetail>();
            DataSet ds = new DataSet();
            Connection.connection con = new Connection.connection();
            ds = con.mydata();
            foreach (DataRow dr in ds.Tables[0].Rows)
            {
                list.Add(new Empdetail
                {
                    EmployeeId = (int)(dr["EmployeeId"]),
                    Name = (string)dr["Name"],
                    Position = (string)dr["Position"],
                    Office = (string)(dr["Office"]),
                    Salary = (int)(dr["Salary"]),
                });
            }
            return Json(list, JsonRequestBehavior.AllowGet);
        }

[{"EmployeeId":1,"Name":"Imran Khan","Position":"PM","Office":"PM House","Salary":1000000}]

控制器：

$(document).ready(function () {
    $("#demoGrid").DataTable({
        "processing": true,
        "serverSide": true,
        "info": true,
        "stateSave": true,
        "lengthMenu": [[10, 20, 50, -1], [10, 20, 50, "All"]],
        "ajax": {
            "url": "/Login/Display",
            "type": "GET"
        },
        "columns": [
            { "data": "EmployeeId", "orderable": true },
            { "data": "Name", "orderable": true },
            { "data": "Position", "orderable": true },
            { "data": "Office", "orderable": true },
            { "data": "Salary", "orderable": true },
        ],
        "order": [[0, "asc"]]
    });
});

public ActionResult Display()
        {
            List<Empdetail> list = new List<Empdetail>();
            DataSet ds = new DataSet();
            Connection.connection con = new Connection.connection();
            ds = con.mydata();
            foreach (DataRow dr in ds.Tables[0].Rows)
            {
                list.Add(new Empdetail
                {
                    EmployeeId = (int)(dr["EmployeeId"]),
                    Name = (string)dr["Name"],
                    Position = (string)dr["Position"],
                    Office = (string)(dr["Office"]),
                    Salary = (int)(dr["Salary"]),
                });
            }
            return Json(list, JsonRequestBehavior.AllowGet);
        }

[{"EmployeeId":1,"Name":"Imran Khan","Position":"PM","Office":"PM House","Salary":1000000}]

您需要从控制器返回

Datatable

的特定格式的数据，如下所示：

    return Json(new
    {
        draw = "1",
        recordsTotal = list.count,
        recordsFiltered = list.count,
        data = List
    }, JsonRequestBehavior.AllowGet);

添加此返回Json（new{draw=“1”，recordsTotal=list.Count，list.Count，data=list}，JsonRequestBehavior.AllowGet）后；我得到了thsi输出{“draw”：“1”，“recordsTotal”：1，“Count”：1，“data”：[{“EmployeeId”：1，“Name”：“Imran Khan”，“Position”：“PM”，“Office”：“PM House”，“Salary”：1000000}}}我在上面缺少一个参数

recordsFiltered

。我已经更新了我的答案。如果您仍然没有在Datatable中获取数据，请检查并让我知道。我仍然获取上述输出。您是否在Datatable中获取数据？如果没有，请检查浏览器控制台是否有任何错误。这可能会有所帮助。我没有在datatable中获取数据，我检查了浏览器控制台，在添加此返回Json（new{draw=“1”，recordsTotal=list.Count，list.Count，data=list}，JsonRequestBehavior.AllowGet）后，它没有显示任何错误；我得到了thsi输出{“draw”：“1”，“recordsTotal”：1，“Count”：1，“data”：[{“EmployeeId”：1，“Name”：“Imran Khan”，“Position”：“PM”，“Office”：“PM House”，“Salary”：1000000}}}我在上面缺少一个参数
