常州信小程序复选框实现多选一功能

功能实现界面

data: {
    checkboxItems: [
      { name: '全天(1-8节)', value: 'allday' },
      { name: '上午(1-4节)', value: 'am' },
      { name: '下午(5-8节)', value: 'pm' },
      { name: '晚上(晚自习)', value: 'night' },
    ]
  }

想要实现的功能

四个复选框中只能选一个，且选中另一个会取消常州游戏开发培训其余选中,且能保存选择的value值

JS代码实现

checkboxChange: function (e) {
    var that = this;
    let checkboxValues=null;
    let checkboxItems = this.data.checkboxItems, values = e.detail.value
    for (var i = 0, lenI = checkboxItems.length; i < lenI; ++i) {
      if(checkboxItems[i].value==values[values.length-1]){
        checkboxItems[i].checked=true;
        checkboxValues = checkboxItems[i].value;
      }
      else{
        checkboxItems[i].checked = false;
      }
    }
    console.log(checkboxValues)
    that.setData({ checkboxItems, checkboxValues })
  }

手机App外包前端代码
