如何使用 JQGrid 解析来自 Controller 的数据以查看?

How to parse data from Controller to view using JQGrid?

我正在尝试将数据从控制器传递到 GQ 网格。我已经实现了 SQL 操作——在另一个文件中选择一行,并将列表类型 List<Models.ViewModel.Itegration> 的对象返回给控制器。我实现了 JsonResult 类型的控制器,其中 returns 数据采用 json 格式。控制器正在使用 [HttpGet] 属性。我附上了我的控制器代码、html、js 文件和问题的屏幕截图。 Google 控制台 没有显示任何问题。 table 正在准备就绪,但正在显示 table 数据。我想正确地“传递数据”存在问题。如果有人可以检查我的代码并让我知道我哪里出错了,那将对我很有帮助。

此外,是否有任何软件可以让我在连接到服务器时检查问题出在哪里,因为在这种情况下 Google 检查工具根本没有帮助。

在我的控制器中,通过使用断点,我检查了 Integrations value = db.GetIntegrationRow(); 我在 value 中得到了正确的值。 控制器:

#region Namespace

using MCNIDev.DBAccess;
using MCNIDev.Models.ViewModel;
using MCNIDev.Processor.Services;

using System.Web.Mvc;

#endregion

namespace MCNIDev.Content
{
    /// <summary>
    /// This controller class is responsible for all action in  Integration view
    /// </summary>
    public class IntegrationsController : Controller
    {
        public ActionResult Details()
        {
            return PartialView();
        }

        /// <summary>
        /// To get the data for JQGrid
        /// </summary>
        [HttpGet]
        public JsonResult Detail()
        {

            IntegrationsProcessor db = new IntegrationsProcessor(new MCNIDbContext());
            Integrations value = db.GetIntegrationRow();

            return new JsonResult()
            {
                               Data = value,
                               JsonRequestBehavior = JsonRequestBehavior.AllowGet
            };
           
        }

    }
}

            root: "",
            page: "page",

        GetValue: GetValue

问题出在控制器。我试图在不告诉 JQGrid 在哪里插入数据的情况下发送数据。

var jsonData = new
            {
                rows = value
            };
            return Json(jsonData, JsonRequestBehavior.AllowGet);

用上面的代码替换下面的代码

return new JsonResult()
            {
                               Data = value,
                               JsonRequestBehavior = JsonRequestBehavior.AllowGet
            };

在我的第一个代码中,我提到了在行中添加我的数据。

return new JsonResult()
            {
                               Data = value,
                               JsonRequestBehavior = JsonRequestBehavior.AllowGet
            };

用下面的代码替换上面的代码。

int totalRecords = value.Count();
   var totalPages = (int)Math.Ceiling((float)totalRecords / (float)rows);
    var JsonData = new
                        {
                            total = totalPages,
                            page,
                            records = totalRecords,
                            rows = value 
                        };
                        return Json(JsonData, JsonRequestBehavior.AllowGet);
