如何取到List类型的返回值data中某一列的值？

Question

```onChange: function (newValue, oldValue) {
                            $.ajax({
                                type: 'post',
                                url: "/DMS/ProductionData/GetListByEquTy",
                                data: { newValue: newValue },
                                async: false,
                                success: function (data) {

                                                                                //该如何取值
                                }

                            });





```        public List<DMS_EquStopTypeModel> GetListByEquTy(string newValue)
        {
            List<DMS_EquStopTypeModel> list = new List<DMS_EquStopTypeModel>();
            MyCommonHelp mycommonHelp = new MyCommonHelp();
            StringBuilder sql = new StringBuilder();
            sql.AppendFormat(@"select Id,EquStop_Desc from DMS_EquStop
            where EquStop_Type = '{0}'", newValue);

            DataTable dt = DBHelp.GetDataTable(sql.ToString());

            list = mycommonHelp.ConvertToList<DMS_EquStopTypeModel>(dt);
            return list;

        }

Answer 1

$.each(data, function (i, item) {
var id=item.Id;
var desc=item.EquStop_Desc
}
);
这样试试

后台方法改成

 public  ActionResult GetListByEquTy(string newValue)
        {
            List<DMS_EquStopTypeModel> list = new List<DMS_EquStopTypeModel>();
            MyCommonHelp mycommonHelp = new MyCommonHelp();
            StringBuilder sql = new StringBuilder();
            sql.AppendFormat(@"select Id,EquStop_Desc from DMS_EquStop
            where EquStop_Type = '{0}'", newValue);

            DataTable dt = DBHelp.GetDataTable(sql.ToString());

            list = mycommonHelp.ConvertToList<DMS_EquStopTypeModel>(dt);
            return Json(list, JsonRequestBehavior.AllowGet);

        }
