话不多说，直接上码，复制粘贴直接上手

html

<view class="radio-box" wx:for="{{radios}}"  key="item.id">
    <lebel class="radio {{ index==sex ? 'on' : ''}}" data-index='{{index}}' data-value='{{item.value}}' bindtap="check">
    <image wx:if='{{index==sex}}' src='../../images/arrow.png'></image>
    </lebel>{{item.label}}
</view>

js

Page({

  data: {
     sex: 0,
    radios: [
      {
        label: '男',
        value: '男',
      },
      {
        label: '女',
        value: '女',
      },
    ]
  },
  check(e) {
    console.log(e)
    var that = this;
    var sex = e.currentTarget.dataset.index
    that.setData({
     sex:sex
    })
  },
