微信小程序单元格嵌入复选框问题
wtml

  <van-checkbox-group value="{{result}}" bind:change="onChangeList">
        <van-cell-group>
          <van-cell 
          wx:for="{{zhuisuall}}" 
          wx:key="index" 
          title="{{item.time}}" 
          label="{{item.code}}"
          value-class="value-class"
          clickable
          data-index="{{index}}" 
          title-width="94%" 
          bind:click="toggle"
          center
          >
           <van-checkbox  name="{{item.code}}" data-data="{{item}}"></van-checkbox>
          </van-cell>
        </van-cell-group>
      </van-checkbox-group>

js错误部分

  toggle(event) {
    const { index } = event.currentTarget.dataset;
    const checkbox = this.selectComponent('.checkboxes-${index}');//报错位置
    console.log(checkbox)
checkbox.toggle();//报错位置
},

控制台显示
