Ajax success returns "undefined" in asp.net core


I'm trying to get the json data by ajax and show them in the view. The data is correct in action method but when I want to show the data in table all the s are showed as undefined and so many rows that I know I don't have this much rows .maybe it is because of for loop and each loop but I really don't know how to fix it. This is the json data:

      {
   "$id": "1",
   "$values": [
  {
     "$id": "2",
      "TicketId": 32,
  "Author": "5aff2283-5e71-4b10-a809-7c0235ccc18d",
  "To": "f956d006-72b7-4a4c-b5cf-9354d6e6f193",
  "Status": 1,
  "priority": 2,
  "TrackingCode": "1bbdd10553634f2fbab1769cbf0b1b44",

    "Description": null,
    "IsDelete": false,
    "CreateDate": "2021-03-17T12:20:46.6002855",
    "EditDate": null,
    "ParentId": null,
    "Roles": null,
    "Id": "f956d006-72b7-4a4c-b5cf-9354d6e6f193",

  },

},
{
  "$id": "4",
  "TicketId": 33,
  "Author": "5aff2283-5e71-4b10-a809-7c0235ccc18d",

  "IsPrivate": false,
  "IsDeleted": false,
  "User": null,
  "ApplicationRole": {
    "$ref": "3"
  },
  "Answer": {
    "$id": "5",
    "AnswerId": 6,
    "TicketId": 33,
    "UserId": "5aff2283-5e71-4b10-a809-7c0235ccc18d",
    "AnswerText": "\u003Cp\u003Ebbbbbb\u003C/p\u003E\r\n",
    "File": null,
    "DateTime": "2021-04-05T11:03:24.6079034",
    "IsDeleted": false,
    "Ticket": {
      "$ref": "4"
    },
    "User": null
  }
} 
]
}

This is the Ajax:

 <script type="text/javascript">

        $(document).ready(function () {
            loadData();
        });
    function loadData() {
        $.ajax({
            url: "/Ticket/GetMyTickets",
            type: "Get",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (ListData) {                    
                var str = "";
                for (var i = 0; i < ListData.length; i++) {
                    $.each(ListData[i], function (index, items) {                          
                        str += "<tr>";
                        str += "<td>" + ListData[i].Status + "</td>";
                        str += "<td>" + ListData[i].priority + "</td>";
                        str += "<td>" + ListData[i].TrackingCode + "</td>";
                        str += "<td>" + ListData[i].CreateDate + "</td>";
                        str += "<td>" + ListData[i].IsPrivate + "</td>";
                        str += "<td>" + ListData[i].To + "</td>";
                        str += "<td><a onclick=Edit(this) data-toggle='modal' data- 
          target='#myModal'>نمایش پاسخ ها</a></td>";

                        str += "</tr>";
                    },
                BodyData.innerHTML = str);
                    $(".TblData tr").fadeIn(1000);

                };

                    }
        });
    }

I searched a lot but I didn't find any solution for the problem.

UPDATE This is the output of console.log(ListData):

      {
      "$id": "2",

Solution

  • According to your json structure you only need one loop to iterate through your json array . So, simply use ListData["$values"] inside $.each and then get respective value using keyname.

    Demo Code :

    //just for demo
    var ListData = {
      "$id": "1",
      "$values": [{
          "$id": "2",
          "TicketId": 32,
          "Author": "5aff2283-5e71-4b10-a809-7c0235ccc18d",
