angular实现商品筛选功能

angular.module("app",[])
.service("productData",function(){
  //通过service方法来定义数据，也可以通过factory方法来定义
  return [
    {
      id:1002,
      name:'HuaWei',
      quantity:200,
      price:4300
    },
    {
      id:2123,
      name:'iphone7',
      quantity:38,
      price:6300
    },
    {
      id:3001,
      name:'XiaoMi',
      quantity:3,
      price:2800
    },
    {
      id:4145,
      name:'Oppo',
      quantity:37,
      price:2100
    },
    {
      id:5563,
      name:'Vivo',
      quantity:23,
      price:2100
    }
  ]
})
//传入用service定义的productData数据依赖
.controller("myCtrl",function($scope,productData){
  $scope.data=productData; //进行相应赋值

  $scope.order=''; //单列排序用，后面详解
  $scope.changeOrder=function(type){
    $scope.orderType=type;
    if($scope.order===''){
      $scope.order='-';
    }else{
