ASP.NET MVC提交LIST列表到后台接收不到数据

兄跌你看到这篇文章的时候已经找到答案了。

我在解决这个问题的端倪的时候已经浪费了我一个下午的休假时间。所以你应该给我一个赞！！！

不废话了上代码：

Entity(Model)

[Serializable]
    public partial class dictionarys
    {
        
        #region Model
        
        public string id
        {
            set;
            get;
        }
        /// <summary>
        /// 
        /// </summary>
        public string parentID
        {
            set;
            get;
        }
        /// <summary>
        /// 
        /// </summary>
        public string text
        {
            set;
            get;
        }
        /// <summary>
        /// 
        /// </summary>
        public string value
        {
            set;
            get;
        }
        /// <summary>
        /// 
        /// </summary>
        public string orderIndex
        {
            set;
            get;
        }
        /// <summary>
        /// 
        /// </summary>
        public bool isSystem
        {
            set;
            get;
        }
        /// <summary>
        /// 
        /// </summary>
        public bool isDel
        {
            set;
            get;
        }
        /// <summary>
        /// 
        /// </summary>
        public DateTime createTime
        {
            set;
            get;
        }
        /// <summary>
        /// 
        /// </summary>
        public DateTime updateTime
        {
            set;
            get;
        }
        #endregion Model

    }

Controllers的代码如下：

public ActionResult Test1()
        {
            List<DapperTemplate.Model.dictionarys> list1 = new List<DapperTemplate.Model.dictionarys>();
            int i = 0;
            while (i < 5)
            {
                list1.Add(new DapperTemplate.Model.dictionarys()
                {
                    id = Guid.NewGuid().ToString(),
                    text = "项目" + i,
                    value = "项目" + i,
                    parentID = "0000-0000-0000-0000-0000",
                    orderIndex = i.ToString(),
                    isSystem = false,
                    isDel = false,
                    createTime = DateTime.Now,
                    updateTime = DateTime.Now,

                });

                i++;
            }

            return View(list1);
        }

View的代码如下：

@model List<DapperTemplate.Model.dictionarys>
<form action="/dictionarys/Test" method="post" id="form1">
        @for (int i = 0; i < Model.Count; i++)
        {
            <div>
                @Html.Raw(string.Format("<input type='text' name='list[{0}].id' value='{1}'/>", i.ToString(), Model[i].id))
                @Html.Raw(string.Format("<input type='text' name='list[{0}].text' value='{1}'/>", i.ToString(), Model[i].text))
                @Html.Raw(string.Format("<input type='text' name='list[{0}].value' value='{1}'/>", i.ToString(), Model[i].value))

            </div>
        }
        <input type="submit" value="提交" />
</form>

点击提交监测Chrome流量发现如下：

发现了一个猫腻这是酱紫的规律：

List[0].propertyName

…

List[1].propertyName

…

List[2].propertyName

…

那么我用jquery的ajax提交一个数据对比一下参数格式。

JavaScript代码如下：

var queryParams = {
                    "list": [
                        {
                            "id": "0001",
                            "text": "0001",
                            "value": "0001",
                            "parentID": "0001",
                            "text": "0001",
                            "orderIndex": "0001",
                            "isSystem": 0,
                            "isDel": 0,

                            "updateTime": "2018-04-22 20:21:00"
                        }, {
                            "id": "0002",
                            "text": "0002",
                            "value": "0002",
                            "parentID": "0002",
                            "text": "0002",

                            "text": "0003",

                        }, {

                            "text": "0005",
                            "value": "0005",
                            "parentID": "0005",
                            "text": "0005",
                            "orderIndex": "0005",
                            "isSystem": 0,
                            "isDel": 0,

                        }
                    ]
                }

               
                $.ajax({
                    type: "POST",
                    dataType: "json",
                    url: "/dictionarys/Test",
                    traditional: false,
                    data: queryParams,
                    success: function (response) {
                        alert(JSON.stringify(response));
                    }
                });

点击提交监测Chrome流量发现如下

发现了一个猫腻这是酱紫的规律：

List[0][ propertyName]

…

List[1][ propertyName]

…

List[2][ propertyName]

…

原来是这里有这么个鬼猫腻

List[2]. propertyName和List[2][ propertyName]

音乐响起！

我们不一样！

Fuck jquery 序列化提交就是这个鬼样子，我也很绝望啊！！！

于是乎我度娘了一下卧槽卧槽卧槽还真的有解决办法了。

JavaScript代码如下：

function parseParam(param, key) {
    var paramStr = ''
    if (param instanceof String || param instanceof Number || param instanceof Boolean) {
        paramStr += '&' + key + '=' + encodeURIComponent(param)
    } else {
        $.each(param, function (i, p) {
            if (p == null || p == undefined)
                return true
            var k = key == null ? i : key + (param instanceof Array ? '[' + i + ']' : '.' + i)
            paramStr += '&' + parseParam(this, k)
        })
    }
    return paramStr.substr(1)
}

调用如下：

 $.ajax({
                    type: "POST",
                    dataType: "json",
                    url: "/dictionarys/Test",
                    traditional: false,
                    data: parseParam(queryParams),
                    success: function (response) {
                        alert(JSON.stringify(response));
                    }
                });

好了可以愉快的玩耍了！！！
