Question

我正在使用数据表从数据库中获取数据。我面临的问题是获取数据的控制器方法正常工作并返回DataSet，我可以在xhr中看到但数据没有显示在html页面中。我无法弄清楚问题所在。在这方面的任何帮助将不胜感激。这是我的代码段。

<table   id="DbTable">
    <thead>
        <tr>
            <th >ID</th>
            <th>Name</th>
            <th>E-mail</th>
            <th>Address</th>
        </tr>
    </thead>


</table>

脚本代码：

 $(document).ready(function () {
        $.ajax({
            url: '@Url.Action("GetCompanies", "Company")',
            method: 'get',
            dataType: 'json',
            success: function (data) {
                $('#DbTable').DataTable({
                    data: data,
                    columns: [
                         { "data": "Id" },
                           { "data": "Name" },
                           { "data": "Email" },
                            { "data": "Address" },
                    ]
                });
            }
        });
    });

这是控制器代码：

    [HttpGet]
    public JsonResult GetCompanies()
    {
        try
        {
            IEnumerable<Company> company = _companyService.GetCompanies().ToList();
            IEnumerable<CompanyListViewModel> viewModelListCompanies = Mapper.DynamicMap<IEnumerable<Company>, IEnumerable<CompanyListViewModel>>(company);


            return new JsonSuccessResult(viewModelListCompanies);

        }
        catch (Exception ex)
        {
            Response.StatusCode = (int)ResponseCode.UnprocessableEntity;
            return new JsonErrorResult(ex.ToString());
        }
    }

JsonSuccessResult类：

public class JsonSuccessResult : JsonResult
{
    public JsonSuccessResult()
    {
        Data = new { Success = true, Error = false, Message = "Data has been saved successfully" };
        ContentEncoding = System.Text.Encoding.UTF8;
        JsonRequestBehavior = JsonRequestBehavior.AllowGet;
    }
    public JsonSuccessResult(MessageCode messageCode)
    {
        Data = new { Success = true, Error = false, Message = MessageDictionary.SuccessMessages[messageCode] };
        ContentEncoding = System.Text.Encoding.UTF8;
        JsonRequestBehavior = JsonRequestBehavior.AllowGet;
    }

    public JsonSuccessResult(string message)
    {
        Data = new { Success = true, Error = false, Message = message };
        ContentEncoding = System.Text.Encoding.UTF8;
        JsonRequestBehavior = JsonRequestBehavior.AllowGet;
    }

    public JsonSuccessResult(IEnumerable enumerable, long totalCount = 0, int limit = 50, int offset = 0)
    {
        Data = new
        {
            Success = true,
            Error = false,
            Message = "Success",
            DataSet = enumerable,
            Limit = limit,
            Offset = offset,
            TotalCount = totalCount,
        };
        ContentEncoding = System.Text.Encoding.UTF8;
        JsonRequestBehavior = JsonRequestBehavior.AllowGet;
    }
    public JsonSuccessResult(object data)
    {
        Data = new
        {
            Success = true,
            Error = false,
            Message = "Success",
            Data = data
        };
        ContentEncoding = System.Text.Encoding.UTF8;
        JsonRequestBehavior = JsonRequestBehavior.AllowGet;
    }
    public JsonSuccessResult(int val)
    {
        Data = new
        {
            Success = true,
            Error = false,
            Message = "Success",
            Data = val
        };
        ContentEncoding = System.Text.Encoding.UTF8;
        JsonRequestBehavior = JsonRequestBehavior.AllowGet;
    }

}

您返回的JsonSuccessResult对象不是数组，它是一个对象，其中包含名为DataSet的属性中的数据。所以你需要改变

success: function (data) {
    $('#DbTable').DataTable({
        data: data,

到

success: function (data) {
    $('#DbTable').DataTable({
        data: data.DataSet,

数据未显示使用数据表
