#components-layout-demo-top-side .logo {
float: left;

</style>
实现效果：
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-menu
v-model:selectedKeys="selectedKeys1"
theme="dark"
mode="horizontal"
:style="{ lineHeight: '64px' }"

<a-menu-item key="/welcome">
<router-link to="/welcome">

</router-link>
</a-menu-item>
<a-menu-item key="/passenger">
<router-link to="/passenger">

</a-menu-item>
</a-menu>

export default defineComponent({

member

<!-- Add "scoped" attribute to limit CSS to this component only -->

<script>
import {defineComponent, ref} from 'vue';
export default defineComponent({

return {
selectedKeys2: ref(['1']),
openKeys:ref(['sub1'])
};
},
});
</script>
<!-- Add "scoped" attribute to limit CSS to this component only -->
<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-menu
v-model:selectedKeys="selectedKeys"
theme="dark"
mode="horizontal"
