goodsPrice 是父组件接收到的数据，想把 goodsPrice 传到子组件priceStyle里

<i-priceStyle priceInt="{{goodsPrice}}" priceFloat="{{goodsPrice}}"></i-priceStyle>

子组件priceStyle.js

methods: {     /**      *      */     test(e) {       String.prototype.moneyFormat = function (returnArr) {         parts = this.replace(',', '').split('.')         parts[1] = (parts[1] = parts[1] || '00') + (parts[1].length < 2 ? '0' : '')         return returnArr ? parts : parts.join('.')       };       Number.prototype.moneyFormat = function (returnArr) {         return this.toString().moneyFormat(returnArr)       };         var price = this.data.goodsPrice       price = price.moneyFormat(1)         this.setData({         priceInt: parts[0],         priceFloat: parts[1]       })     }   }

子组件priceStyle.wxml

<view class="price"><sub>￥</sub>{{priceInt}}<sub>.{{priceFloat}}</sub></view>

现在子组件接收到父组件传过来的“goodsPrice”值之后，显示的结果是错的。
