本文实例讲述了微信小程序实现用table显示数据库反馈的多条数据功能。分享给大家供大家参考,具体如下:
解决了微信小程序自定义表格,并显示的多条数据的问题。
index.wxml
- <view>
- <text>我的调查问卷</text>
- <scroll-view scroll-x="true" style=" white-space: nowrap; display: flex">
- <view class="table">
- <view class="tr bg-header">
- <view class="th">姓名</view>
- <view class="th">性别</view>
- <view class="th">年龄</view>
- </view>
- <view class="tr bg-items" wx:for = "{{items}}" wx:key="">
- <text class="td">{{item.name}}</text>
- <text class="td">{{item.gender}}</text>
- <text class="td">{{item.age}}</text>
- </view>
- </view>
- </scroll-view>
- <button bindtap="change">查看我的数据</button>
- </view>

data.php
- <?php
