 el: '#app',
 data: {
  totalMoney: 0,

 },
 filters: {
  formatMoney: function (value) {
   return "￥ " + value.toFixed(2);
  },
 },
 mounted: function() {
  this.$nextTick(function(){
   this.cartView();
  });
 },
 methods: {
  cartView: function() {
   let _this = this;
   this.$http.get("data/cartData.json", {"id":123}).then(res=>{
   this.productList = res.body.result.list;
   this.totalMoney = res.body.result.totalMoney;
  });
  }
 }
});
Vue.filter("money", function(value,type) {
 return "￥ "+value.toFixed(2) + type;
})

changeMoney: function(product, way){
if(way>0){
 product.productQuentity++;
 }else{
 product.productQuentity--;
 if(product.productQuentity<1){
  product.productQuentity = 1;
 }
 }
}

selectedProduct: function (item) {
 if(typeof item.checked == 'undefined'){
  Vue.set(item, "checked", true);
 }else {
  item.checked = !item.checked;
 }
}
