JSON对象属性来了为NULL [英] JSON Object Properties are coming as NULL

问题描述

我在ASP.Net MVC剑道UI电网。我试图 JSON 对象传递给控制器​​。虽然我在控制器中得到一个对象，属性都来为 NULL （名字，姓氏）。我们如何纠正？

请注意：对象不是null;但属性是空的对象

JSON

  VAR NewPerson =新的对象（）;
   NewPerson.FirstName =A;
   NewPerson.LastName =B;   VAR json1 = {myPerson：NewPerson};
   返回json1;
 

的JavaScript

  $（＆LT; D​​IV /＆gt;中）。appendTo（e.detailCell）.kendoGrid（{
            数据源： {
                类型：aspnetmvc阿贾克斯
                运输： {                    数据类型：JSON
                    //，键入：POST
                    阅读：{
                        网址：首页/ GetItemsData
                        数据：功能（）
                        {
                            VAR NewPerson =新的对象（）;
                            NewPerson.FirstName =A;
                            NewPerson.LastName =B;                            VAR json1 = {myPerson：NewPerson};
                            返回json1;
                        }
                    }                }，
                模式：{
                    型号：{
                        字段：{
                            程序：{
                                ITEMID：数字，
                            }，
                            ItemDescription：{类型：串}
                        }
                    }，
                    总说：总，
                    数据：项目
                }，
                serverPaging：真实，
                serverSorting：真实，
                serverFiltering：真实，
                每页：5
            }，
            滚动：假的，
            排序：真实，
            分页：真实，
            列： [
                        {域：项ID，名称：项目标识，宽：70像素}，
                        {场：ItemDescription，标题：项目说明宽110px}
            ]
        }）;
 

控制器

 公共JsonResult GetItemsData（人myPerson，[DataSourceRequest] DataSourceRequest要求）
    {
    }
 

解决方案

我解决了问题。对于其他人的利益，我将在这里把解决方案。

当我删除了NewPerson变量的问题得到了解决。现在我直接赋值给myPerson。和相应的网络流量如下。

  VAR myPerson = {};
 myPerson.FirstName =A;
 myPerson.LastName =B; 数据：功能（）
 {    返回myPerson;
 }
 

更新

有关的getJSON方法，语法将如下图所示，在更好的JSON数据结构

  VAR searchCriteria = {};
sea​​rchCriteria.Accrual =A;
sea​​rchCriteria.Brand =B;$ .getJSON（URL，searchCriteria
，功能（数据）{
    如果（data.length）{
        警报（成功）;
    }}）;

I have Kendo UI grid in ASP.Net MVC. I am trying to pass JSON object to controller. Though I am getting an object in the controller, the properties are coming as NULL (FirstName, LastName). How can we correct it?

Note: The object is not null; but the properties are null in the object

JSON

   var NewPerson = new Object();
   NewPerson.FirstName = "A";
   NewPerson.LastName = "B";

   var json1 = { myPerson: NewPerson };
   return json1;

JavaScript

     $("<div/>").appendTo(e.detailCell).kendoGrid({
            dataSource: {
                type: "aspnetmvc-ajax",
                transport: {

                    dataType: "json",
                    //,type: "POST"
                    read: {
                        url: "Home/GetItemsData",
                        data: function ()
                        {
                            var NewPerson = new Object();
                            NewPerson.FirstName = "A";
                            NewPerson.LastName = "B";

                            var json1 = { myPerson: NewPerson };
                            return json1;
                        }
                    }



                },
                schema: {
                    model: {
                        fields: {
                            Program: {
                                ItemID: "number",
                            },
                            ItemDescription: { type: "string" }
                        }
                    },
                    total: "Total",
                    data: "Items"
                },
                serverPaging: true,
                serverSorting: true,
                serverFiltering: true,
                pageSize: 5
            },
            scrollable: false,
            sortable: true,
            pageable: true,
            columns: [
                        { field: "ItemID", title: "Item Id", width: "70px" },
                        { field: "ItemDescription", title: "Item Description", width: "110px" }
            ]
        });

Controller

 public JsonResult GetItemsData(Person myPerson, [DataSourceRequest] DataSourceRequest request)
    {
    }

解决方案

I resolved the issue. For the benefit of others I will put the solution here.

The issue got resolved when I removed the NewPerson variable. Now I am directly assigning values to the myPerson. And the corresponding network traffic is listed below.

 var myPerson = {};
 myPerson.FirstName = "A";
 myPerson.LastName = "B";

 data: function () 
 {

    return myPerson;
 }

UPDATE

For getJSON Method, the syntax will be as shown below, as mentioned in Better JSON data structure

var searchCriteria = {};
searchCriteria.Accrual = "A";
searchCriteria.Brand = "B";

$.getJSON(url, searchCriteria
, function (data) {
    if (data.length) {
        alert('Success');
    }

});
