angular迴圈物件屬性實現動態列

優點：儲存物件，在只儲存一條資料

缺點：新增物件屬性需要修改表結構、程式碼，然後重新重新發布

實現思路

1）資料庫建立表（物件）、建立欄位（物件屬性）

2）根據表（物件）、欄位（物件屬性）生成配置表

3）根據表（物件）、欄位（物件屬性）生成三層架構

4）demo程式碼如下

1.介面程式碼：

using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Logging;
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Threading.Tasks;
using WebApplication1.Models;
 
namespawww.cppcns.com
 
ce WebApplication1.Controllers
{
    public class HomeController : Controller
    {
        public IActionResult Index(string objecttype)
        {
            ViewBag.objecttype = objecttype;
            return View();
        }
        [HttIzxpqaZApPost]
        public JsonResult GetItem(string objecttype)
        {
            if (objecttype == "student")
            {
                StIzxpqaZA
 
udent item = new Student
                {
                    no = "S001",name = "張三",gender = "男",};
                List<Column> columns = new List<Column>();
                columns.Add(new Column { columnname = "no",displaynname="學號" });
                columns.Add(new Column { columnname = "name",displaynname = "姓名" });
                columns.Add(new Column { columnname = "gender",displaynname = "性別" });
                return Json(new { code = "1",msg = "",item = item,columns = columns });
            }
            else
            {
                School item = new School
                {
                    no = "S001",name = "浙江大學",address = "浙江",displaynname = "編碼" });
                columns.Add(new Col
 
umn { columnname = "name",displaynname = "名稱" });
                columns.Add(new Column { columnname = "address",displaynname = "地址" });
                return Json(new { code = "1",columns = columns });
            }
        }
 
        [HttpPost]
        public JsonResult SaveItem(string objecttype,string itemstring)
        {
            if (objecttype == "student")
            {
                Student item = JsonConvert.DeserializeObject<Student>(itemstring);
            }
            else
            {
                School item = JsonConvert.DeserializeObject<School>(itemstring);
            }
            return Json(new { ResultCode = "1",ResultMessage = "儲存成功！" });
        }
    }
    public class Student
    {
        public string no { get; set; }
        public string name { get; set; }
        public string gender { get; set; }
    }
    public class School
    {
        public string no { get; set; }
        public string name { get; set; }
        public string address { get; set; }
    }
    public class Column
    { 
        public string columnname { get; set; }
        public string displaynname { get; set; }
    }
}

2.angularjs前端程式碼

@{
    ViewData["Title"] = "Home Page";
}
 
<script type="text/">
    var app = angular.module("my_app",[]);
    app.controller('my_controller',function ($scope) {
        //儲存
        $scope.saveItem = function () {
            var itemstring = JSON.stringify($scope.item)
            $.post('@Url.Action("SaveItem","Home")',{ objecttype: '@ViewBag.objecttype',itemstring: itemstring },function (data) {
 
            });
        }
        //獲取
        $scope.getItem = function () {
            $.post('@Url.Action("GetItem",{ objecttype: '@ViewBag.objecttype' },function (result) {
                $scope.item = result.item;
                $scope.columns = http://www.cppcns.comresult.columns;
                $scope.$apply();
            });
        }
        $scope.getItem();
    });
</script>
<div>
    <ul>
        <li ng-repeat="column in columns">
            <span>{{column.displaynname}}</span>
            <input ng-if="item[column.columnname]&&item[column.columnname].length" ng-model="item[column.columnname]" />
        </li>
    </ul>
    <input type="button" value="儲存" ng-click="saveItem();" />
</div>
