示例代码

以下是一个绑定了标签的复选框和单选框的示例代码，可以参考一下：

<view class="section section_gap">
<view class="section__title">表单组件在label内</view>
<checkbox-group class="group" bindchange="checkboxChange">
    <view class="label-1" wx:for-items="{{checkboxItems}}">
        <label>
            <checkbox hidden value="{{item.name}}" checked="{{item.checked}}"></checkbox>
            <view class="label-1__icon">
                <view class="label-1__icon-checked" style="opacity:{{item.checked ? 1: 0}}"></view>
            </view>
            <text class="label-1__text">{{item.value}}</text>
        </label>
    </view>
</checkbox-group>
</view>

<view class="section section_gap">
<view class="section__title">label用for标识表单组件</view>
<radio-group class="group" bindchange="radioChange">
    <view class="label-2" wx:for-items="{{radioItems}}">
        <radio id="{{item.name}}" hidden value="{{item.name}}" checked="{{item.checked}}"></radio>
        <view class="label-2__icon">
            <view class="label-2__icon-checked" style="opacity:{{item.checked ? 1: 0}}"></view>
        </view>
        <label class="label-2__text" for="{{item.name}}"><text>{{item.name}}</text></label>
    </view>
</radio-group>
</view>

Page({
  data: {
    checkboxItems: [
      {name: 'USA', value: '美国'},
      {name: 'CHN', value: '中国', checked: 'true'},
      {name: 'BRA', value: '巴西'},
      {name: 'JPN', value: '日本', checked: 'true'},
      {name: 'ENG', value: '英国'},
      {name: 'TUR', value: '法国'},
    ],
    radioItems: [
      {name: 'USA', value: '美国'},
      {name: 'CHN', value: '中国', checked: 'true'},
      {name: 'BRA', value: '巴西'},
      {name: 'JPN', value: '日本'},
