我在剃刀www.example.com工作asp.net。我面临的问题是我无法将json返回的数据追加到html表中
当尝试使用jQuery AJAX 追加表html时，我得到错误
无法读取空阅读的属性，正在读取函数中的公司名称。对象中的每个。成功
我的代码详细信息
第一次显示数据时

<table id="myDataTable" class="table" style="margin-top:20px;">
    <thead>
        <tr>
            <th>Company Name</th>
            <th>Branch Name</th>
            <th>User Name</th>
            <th>User Type</th>
            <th>Actions</th>
        </tr>
    </thead>
    <tbody>

        <tr>
            <td>@Model.MyData.CompanyName</td>
            <td>@Model.MyData.BranchName</td>
            <td>@Model.MyData.UserName</td>
            <td>@Model.MyData.UserType</td>
            <td>
                <button id="editDataBtn" style="width:100px;" class="btn btn-primary edit-btn" data-id="@Model.MyData.ID">Edit</button>
            </td>
        </tr>

    </tbody>
</table>

要通过在表html上追加来重新加载数据，请执行以下操作

$("#updatedatabtn").click(function () {
                var userId = $("#userId").val();
                $.ajax({
                    url: '?handler=RefreshDataTable',

                    dataType: 'json',
                    data: { UserId: userId },
                    success: function (result) {
                        console.log(result);
                        $("#myDataTable tbody").empty();
                        $.each(result, function (index, item) {
                            $("#myDataTable tbody").append("<tr><td>" + item.CompanyName + "</td><td>" + item.BranchName + "</td><td>" + item.UserName + "</td> </tr>");
                        });
                    },
                    error: function (xhr, status, error) {
                        console.error("AJAX request failed: " + error);
                    }
                });
            });
    [BindProperty]
    public UserDto MyData { get; set; }

public JsonResult OnGetRefreshDataTable(string UserId)
        {
            var result = userService.GetUserDetails(UserId.ToString());
            MyData = result.Result;
            return new JsonResult(MyData);

        }

当调用RefreshDataTable的API时，我得到以下返回数据：

{
    "vLoginName": "9595",
    "vPassword": "qvUBTS3WkZ/mFbpDQjQsFjsyLR9ehAEWqLedckm3pKZgUlZ/IsH9PFuDXsOto3dXgByvSXRS9ynsBahj38SSkw==",
    "userMode": "A",
    "id": 230,
    "failedAttempts": 0,
    "userName": "ADC Test User",
    "branchName": "KFoundation-Aweer",
    "branchCode": "101KF06",
    "companyName": "Union Co-Operative Society",
    "userType": "S ",
    "accountStatus": null
}

返回的函数将只返回一个对象，因为我显示用户详细信息。
