其中header和sider是先前封装的组件
router中显示的就是子页面http://localhost:9001/welcome的内容
给header和sider组件添加menu
menu
<a-menu-item key="/welcome"><router-link to="/welcome"><coffee-outlined /> 欢迎</router-link></a-menu-item><a-menu-item key="/passenger"><router-link to="/passenger"><user-outlined /> 乘车人管理</router-link></a-menu-item>
header
<template><a-layout-header class="header"><div class="logo" /><div style="float: right; color: white;">您好：{{member.mobile}} <router-link to="/login" style="color: white;">退出登录</router-link></div><a-menuv-model:selectedKeys="selectedKeys1"theme="dark"mode="horizontal":style="{ lineHeight: '64px' }"><a-menu-item key="/welcome"><router-link to="/welcome"><coffee-outlined /> 欢迎</router-link></a-menu-item><a-menu-item key="/passenger"><router-link to="/passenger"><user-outlined /> 乘车人管理</router-link></a-menu-item></a-menu>

import {defineComponent, ref} from 'vue';
import store from "@/store";export default defineComponent({name: "the-header-view",setup() {let member = store.state.member;return {selectedKeys1: ref(['2']),member};},
});

<style scoped></style>实现效果：
但是，这时的header和sider的菜单显示并不同步，还会出现菜单与内容不符的问题
为解决这个问题，在header和sider中分别编写watch，监视地址的router地址的变化
watch
const selectedKeys = ref([]);watch(() => router.currentRoute.value.path, (newValue) => {console.log('watch', newValue);selectedKeys.value = [];selectedKeys.value.push(newValue);}, {immediate: true});
header
<template><a-layout-header class="header"><div class="logo" /><div style="float: right; color: white;">您好：{{member.mobile}} <router-link to="/login" style="color: white;">退出登录</router-link></div><a-menuv-model:selectedKeys="selectedKeys"theme="dark"mode="horizontal":style="{ lineHeight: '64px' }"><a-menu-item key="/welcome"><router-link to="/welcome"><coffee-outlined /> 欢迎</router-link></a-menu-item><a-menu-item key="/passenger"><router-link to="/passenger"><user-outlined /> 乘车人管理</router-link></a-menu-item></a-menu>
