命名路由:

作用: 命名路由可以简化路由跳转及传参.
给路由规则命名:

routes:[
  {
    name:'zhuye',
    path:'/home',
    component:Home
  },
  {
    name:'xinwen',
    path:'/news',
    component:News,
  },
  {
    name:'guanyu',
    path:'/about',
    component:About
  }
]

跳转路由:

<!--简化前：需要写完整的路径（to的字符串写法） -->
<router-link to="/news/detail">跳转</router-link>

<!--简化后：直接通过名字跳转（to的对象写法配合name属性） -->
<router-link :to="{name:'guanyu'}">跳转</router-link>

嵌套路由:

编写news的子路由: Detail.vue
配置路由规则, 使用children配置项:

const router = createRouter({
  history:createWebHistory(),
	routes:[
		{
			name:'zhuye',
			path:'/home',
			component:Home
		},
		{
			name:'xinwen',
			path:'/news',
			component:News,
			children:[
				{
					name:'xiang',
					path:'detail',
					component:Detail
				}
			]
		},
		{
			name:'guanyu',
			path:'/about',
			component:About
		}
	]
})
export default router

跳转路由(记得要加完整路径):

<router-link to="/news/detail">xxxx</router-link>
<!-- 或 -->
<router-link :to="{path:'/news/detail'}">xxxx</router-link>

记得去home组件中预留一个<router-view>

<template>
  <div class="news">
    <nav class="news-list">
      <RouterLink v-for="news in newsList" :key="news.id" :to="{path:'/news/detail'}">
        {{news.name}}
      </RouterLink>
    </nav>
    <div class="news-detail">
      <RouterView/>
    </div>
  </div>
</template>
