//在组件上使用 wx:for 控制属性绑定一个数组，即可使用数组中各项的数据重复渲染该组件。//默认数组的当前项的下标变量名默认为 index，数组当前项的变量名默认为 item<view wx:for="{{array}}">  {{index}}: {{item.message}}</view>//或者//使用 wx:for-item 可以指定数组当前元素的变量名，//使用 wx:for-index 可以指定数组当前下标的变量名：<view wx:for="{{array}}" wx:for-index="idx" wx:for-item="itemName">  {{idx}}: {{itemName.message}}</view>

//存储this.setData({        result: event.detail      }); //使用 this.data.result
