数据格式是嵌套循环，通过两个 for 循环展示，通过wx:for-index 定义 index,同时给 radio 赋值 value,value由两个循环的自定义属性index,且把两个index串联起来,例如： 00、01等

<view class="goods-list">
  <radio-group bindchange="listenerRadioGroup">
    <block wx:for="{{lists}}" wx:key="{{item.id}}" wx:for-index="index">
      ......
      <view class="item" wx:for="{{item.list}}" wx:for-item="list" wx:for-index="index1" wx:key="{{list.commodityId}}">
        <radio value="{{ index + '' + index1 }}"></radio>
        ......
      </view>
    </block>
  </radio-group>
</view>

// 选择单选
  listenerRadioGroup: function(e) {
    //获取当前点击的值
    let index = e.detail.value
    // 通过index 拿到数值，作为lists 和 list 的下标
    let data = this.data.lists[index[0]].list[index[1]];
    console.log(data);
    var that = this
    that.setData({
      goods: JSON.stringify(data)
    })
  },
