Vue Router实现多层嵌套路由的导航的详细指南

npm install vue-router@next

// router/index.js
import { createRouter, createWebHistory } from 'vue-router';
import Home from '../views/Home.vue';
import About from '../views/About.vue';
import Nested from '../views/Nested.vue';

const routes = [
  {
    path: '/',
    name: 'Home',
    component: Home
  },
  {
    path: '/about',
    name: 'About',
    component: About
  },
  {
    path: '/nested',
    component: Nested,
    children: [
      {
        path: 'child',
        name: 'Child',
        component: () => import('../views/Child.vue')
      },
      {
        path: 'grandchild',
        name: 'GrandChild',
        component: () => import('../views/GrandChild.vue')
      }
    ]
  }
];

const router = createRouter({
  history: createWebHistory(process.env.BASE_URL),
  routes
});

export default router;

// main.js
import { createApp } from 'vue';
import App from './App.vue';
import router from './router';

createApp(App).use(router).mount('#app');

<template>
  <div id="app">
    <router-link to="/">Home</router-link>
    <router-link to="/about">About</router-link>
    <router-link to="/nested">Nested</router-link>
    <router-view></router-view>
  </div>
</template>

<script setup>
// 使用 setup 语法糖
</script>

<template>
  <div>
    <h1>Nested Route</h1>
    <router-link to="/nested/child">Go to Child</router-link>
    <router-link to="/nested/grandchild">Go to GrandChild</router-link>
    <router-view></router-view>
  </div>
</template>

<script setup>
import { defineAsyncComponent } from 'vue';
import Nested from './views/Nested.vue';

const Child = defineAsyncComponent(() => import('./views/Child.vue'));
const GrandChild = defineAsyncComponent(() => import('./views/GrandChild.vue'));
</script>
