// 点击商品进入详情页
  hClickDetails(e){
    // 被点击商品的信息
    var nowdata = e.currentTarget.dataset.nowdata
    //将对象转为string
    var queryBean = JSON.stringify(nowdata)
    wx.navigateTo({
      url:'../../shop/details/details?queryBean=' + queryBean,  
    })
  },

onLoad: function (options) {
    var queryBean = JSON.parse(options.queryBean)
    this.setData({
      detailsData: queryBean
    })
    console.log(this.data.detailsData);
  },
