初始数据(默认checked:false): radioItems: [{name:‘处理中’,value: ‘2’,checked: ‘false’},{name:‘完成’,value: ‘1’,checked: ‘false’},{name:‘拒绝’,value: ‘3’,checked: ‘false’}]
循环:
<radio class="radio" wx:for="{{radioItems}}" wx:key="value" value="{{item.value}}" checked="{{item.checked}}">{{item.name}}</radio>
显示结果:
