本人拿到的需求是投票类型，所以数据是后端传过来的数据，类似选择题也可以参考此方法，但是如果是一个页面只展示一个的这种就不适用。
效果图：

<view class="">
          <view wx:for="{{ITEMSLIST}}" wx:key="index" class="guiyue-item" >
              <view class="guiyue-item-title">
                    <view>{{item.TITLE}}</view>
              </view>
                  <view class="weui-cells weui-cells_after-title">
                        <radio-group bindchange="radioChange" data-index="{{index}}">
                        <label class="weui-cell weui-check__label" wx:for="{{item.zhuangtai}}" wx:for-item="value" wx:key="{{value}}"  data-seleindex="{{item.ID}}">

                        <view class="weui-cell__hd">
                              <radio value="{{value.type}}" />
