Angular实现购物车计算实例代码有什么？

 public class ShoppingCar
 {
  public string Title { get; set; }
  public decimal UnitPrice { get; set; }
  public int Count { get; set; }
 }

public ActionResult GetCar()
  {
   List<ShoppingCar> cars = new List<ShoppingCar>
   {
    new ShoppingCar { Title="苹果",Count=1,UnitPrice=2.5m},
    new ShoppingCar { Title="香蕉",Count=3,UnitPrice=1.5m},
    new ShoppingCar { Title="苦瓜",Count=1,UnitPrice=3.5m},
    new ShoppingCar { Title="黄瓜",Count=3,UnitPrice=2.2m}
   };
   return Json(cars,JsonRequestBehavior.AllowGet);
  }

  public ActionResult AddCar(List<ShoppingCar> car)
  {
   return Json("ok", JsonRequestBehavior.AllowGet);
  }

 <div ng-app="DemoApp" ng-controller='CartController'>
  <table class="table table-striped">
   <thead>
    <tr>
     <td>标题</td>
     <td>单价</td>
     <td>数量</td>
     <td>小计</td>
     <td>删除</td>
    </tr>
   </thead>
   <tbody>
    <tr ng-repeat="item in ShoppingCar">
     <td>{{item.Title}}</td>
     <td>{{item.UnitPrice}}</td>
     <td>
      <input type="text" ng-cloak ng-model="item.Count" style="width:50px;text-align:center;">
      <button my-adds ng-click="UpdateCar(item.Title,1)" ng-class="{cursors:true}">+</button>
      <button my-minus ng-click="UpdateCar(item.Title,-1)" ng-class="{cursors:true}">-</button>
     </td>
     <td>{{item.Count*item.UnitPrice | number:2}}</td>
     <td><button my-minus ng-click="UpdateCar(item.Title,-100)" ng-class="{cursors:true}">删</button></td>
    </tr>
   </tbody>
  </table>
  <p ng-init=0>总价格：{{ total | number:2}}</p>
  <button type="button" ng-click="submit()">提交</button>
 </div>

 var app = angular.module('DemoApp', []);
