tabs 选项卡组件 如何设置 swiperClass等同于子元素高度？ DEMO 中 swiperClass = weui-tabs-swiper ，默认是100px。但是怎么确认（<view class="tab-content" slot="tab-content-{{index}}"> ）里面的子元素高度呢？ .weui-tabs-swiper { width: 100%; height: 100px; } https://developers.weixin.qq.com/miniprogram/dev/extended/component-plus/tabs.html

我有一个云函数，目的就是将名为`event.database_collection_name`的collection中一组指定id的数据中liked字段加一，代码如下： // 云函数入口文件 const cloud = require('wx-server-sdk') cloud.init({ env: 'my_env' }) const db = cloud.database({ env: 'my_env' }) // 云函数入口函数 exports.main = async(event, context) => { // console.log(event.database_collection_name) // console.log(event.ids) 这里确保输入的正确性 const _ = db.command db.collection(event.database_collection_name).where({ _id: _.in(event.ids) }).update({ data: { liked: _.inc(-1) }, success: function (res) { console.log(res) }, fail: function (e) { console.log(e) } }) } 者这个函数在本地调试时能够正常生效，同样的测试数据，云端测试结果返回OK但是数据库中数据没有改变。
