创建组件：
选项卡tab组件：
<template>
<view class="tab">
<scroll-view class="tab-scroll" scroll-x>
<view class="tab-scroll_Box">
<view v-for="item in list" class="tab-scroll_item">{{item.name}}</view>

选项卡数据：
新建云函数：
起名创建后：
打开web控制台：
get_label云函数：
'use strict'; // 获取数据库的引用 const db = uniCloud.database(); exports.main = async (event, context) => { // 拿到label数据表 let label = await db.collection('label').get(); //返回数据给客户端 return { code:200, msg:'数据请求成功', data:label.data } };
tabbar的index.vue:
<template>
<view class="navbar">
<!-- 自定义组件导航栏 -->
<navbar></navbar>
<!-- 把拿到的数据传递给tab组件 -->
<tab :tabList="tabList"></tab>
<!-- <view v-for="item in 100">测试</view> -->
</view>
</template>
<script>
// easycom components/组件名/组件名.vue 属于局部引入，比如components中有很多组件，只有用到了才会编译到项目中
// import navbar from '@/components/nav-bar/nav-bar.vue'
export default {
// components:{
// navbar,
// },
data() {
return {
tabList :[],
}
},
onl oad() {
this.getLabel();
},
methods: {
getLabel(){
// 调用云函数API
uniCloud.callFunction({
// 是哪个云函数
name:'get_label',
// 方式一
// success(res) {
// console.log(res)
// this.tabList = res.result.data;
// }
// 方式二
}).then(res=>{
let {result} = res;
this.tabList = result.data;
