Docker笔记：容器转换成镜像，导出导入镜像，数据拷贝，查看日志

        <radio-group bindchange="radioChange">
          <label class="flRlist" wx:for="{{productList}}" wx:key="index">           
            <view class="flName">{{item.name}}</view>
            <view class="flZT">
              <radio color="#74bfe7" style="transform:scale(0.8);" value="{{item.value}}" checked="true"  class="flxzys"/>
            </view>
          </label>
        </radio-group>

radio .wx-radio-input{width:35rpx;height:35rpx;border-radius:50%;border:2rpx solid #000;background:0 0}
radio .wx-radio-input.wx-radio-input-checked{width:35rpx;height:35rpx;border:2rpx solid #000;background-color:#fff!important}
radio .wx-radio-input.wx-radio-input-checked::before{width:35rpx;height:35rpx;border-radius:50%;width:20rpx;height:20rpx;line-height:20rpx;text-align:center;font-size:0rpx;color:transparent;background:#000;transform:translate(-50%,-50%) scale(1)}

  data: {
    productList: [
      {value: 'USA', name: '美国'},
      {value: 'CHN', name: '中国', checked: 'true'},
      {value: 'BRA', name: '巴西'},
      {value: 'JPN', name: '日本'},
      {value: 'ENG', name: '英国'},
      {value: 'FRA', name: '法国'},
    ]
  },

二：

<view class="flZT">
              <radio color="#74bfe7" style="transform:scale(0.8);" value="{{item.value}}" checked="true"  class="flxzys"/>
            </view>

  //单选
  radioChange:function(e){
    //获取单选数据
    console.log(e.detail.value)//输出的是{{item.name}}的值
