better-scroll横向滚动，初始化宽度和请求数据之间

请求数据

需要初始化的页面

 mounted() {
    this.$store.dispatch('getGoodsList', () => {
      // this._initScorll()
    })
}

vuex中

const actions = {
  // 1.获取了goodsList,同时赋值了goodsList和recommendList
  async getGoodsList(context, callback) {
    const result = await getShopsGoods()
    if (result.code === 0) {
      const goodsList = result.data
      //三级菜单数据渲染
      const recommendList = result.data[0].foods
      context.commit(SET_GOODS_LIST, { goodsList, recommendList })
      callback && callback()
    }
  }
}

初始化

_initScorll() {
      // 设置content的宽度
      if (this.recommendList) {
        let itemWidth = 150
        let margin = 8
        let width = (itemWidth + margin) * this.recommendList.length
        this.$refs.recommendContent.style.width = width + 'px'
        this.$nextTick(() => {
          if (!this.picScroll) {
            this.picScroll = new BScroll('.recommend-wrapper', {
              // click: true, //会触发两次点击
              scrollX: true
            })
          }
        })
      }
    }
