做了一个多选和单选按钮测试，发现有一个按钮总是选不上或勾不掉，不知@白开水 老师有无办法

页面：

<radio-group bindchange=‘radio1Change’>

<label style=‘display:block’ wx:for=’{{items1}}’ wx:key=‘name’>

<radio value=’{{item.name}}’ checked=’{{item.checked}}’></radio>

{{item.value}}

</label>

</radio-group>

<view style=‘margin-top:30rpx;margin-bottom:30rpx;border-top:1px solid #000’>

</view>

<radio-group bindchange=‘radio2Change’>

<label style=‘display:block’ wx:for=’{{items2}}’ wx:key=‘name’>

<radio value=’{{item.name}}’ checked=’{{item.checked}}’></radio>

{{item.value}}

</label>

</radio-group>

js代码：

Page({

  /**

   * 页面的初始数据

   */

  data: {

   items1: [

     { name: ‘USA’, value: ‘美国’ },

      { name: ‘CHN’, value: ‘中国’},

      { name: ‘BRA’, value: ‘巴西’ },

      { name: ‘JPN’, value: ‘日本’ },

      { name: ‘ENG’, value: ‘英国’ },

      { name: ‘TUR’, value: ‘法国’ },

    ],

    items2: [

      { name: ‘BEIJING’, value: ‘北京’, checked: ‘true’ },

      { name: ‘SHANGHAI’, value: ‘上海’ },

      { name: ‘shanGDONG’, value: ‘山东’ },

      { name: ‘GUANGDONG’, value: ‘广东’ },

      { name: ‘SHENZHEN’, value: ‘深圳’ },

      { name: ‘HANGZHOU’, value: ‘杭州’ }

    ],

    selectedItem1: [],

    selectedItem2: []

  },

  radio1Change: function (e) {

    var selectedItems = e.detail.value;

    console.log(‘checkBox1发生的change事件，携带value值为’, selectedItems)

    this.setData({

      selectedItems1: selectedItems

    })

    console.log(‘data中的selectedItems1的值：’, this.data.selectedItems1)

  },

  radio2Change: function (e) {

    var selectedItems = e.detail.value;

    console.log(‘checkBox2发生的change事件，携带value值为’, e.detail.value)

    this.setData({

      selectedItems2: selectedItems

    })

    console.log(‘data中的selectedItems2的值：’, this.data.selectedItems2)

  }

})
