data数据复杂时怎么setData

 _getGoodsData(type) {
    const page = this.data.goods[type].page + 1
    getGoodsData(type, page).then(res => {
      const list = res.data.data.list
      const oldList = this.data.goods[type].list
      oldList.push(...list)   //不用伪数组的话会变成一个二维数组
      const listText = `goods.${type}.list` //用反引号解析变量拼接字符串
      const pageText = `goods.${type}.page`
      this.setData({
        [listText]: oldList,   //用中括号包裹字符串的变量名才会被解析
        [pageText]: page
      })

    })
  },
goods数据格式是：

  goods: {
      'pop': {
        page: 0,
        list: []
      },
      'new': {
        page: 0,
        list: []
      },
      'sell': {
        page: 0,
        list: []
      },
    }
  },
