Native使用Mobx实现购物车功能(3)

import { observable, action, computed, autorun } from 'mobx'; export default class MobxStore { @observable itemData = {} //设置数据 replace = (data) => { this.itemData = data; } //按下的反选 itemPress = () => { let i = 0; this.itemData.datas.map((item) => { if (item.isSelect != true) { i += 1; } }); if (i == 0) { this.itemData.isAllSelect = true; } else { this.itemData.isAllSelect = false; } } //加 increase = (money) => { this.itemData.totalMoney += money; } //减 reduce = (money) => { this.itemData.totalMoney -= money; } //全选 selectAll = () => { this.itemData.isAllSelect = !this.itemData.isAllSelect; this.itemData.totalMoney = 0; if (this.itemData.isAllSelect) { for (let i = 0; i < this.itemData.datas.length; i++) { this.itemData.totalMoney += this.itemData.datas[ i ].money * this.itemData.datas[ i ].count; } } } }
