路由Vue Router基本用法

路由的作用是根据URL来匹配对应的组件，并且无刷新切换模板的内容。vue.js中，可使用Vue Router来管理路由，让构建单页应用更加简单。

一、效果

二、实现

1.项目中安装Vue Router插件

pnpm install vue-router@lastest

2.main.js

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'

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

3.   scr/views/Home.vue

<template>
    <div id="app">
        <h1>hello vite</h1>
    </div>
</template>

    src/views/About.vue

<template>
    <div id="app">
        <h1>hello vite about</h1>
    </div>
</template>

       src/views/news.vue

<template>
    <div id="app">
        <h1>hello vite news</h1>
    </div>
</template>

4.src/router/index.js:

import { createRouter, createWebHistory } from 'vue-router'

import Home from '../views/Home.vue'
import News from '../views/News.vue'
import About from '../views/About.vue'

const router = createRouter({
  history: createWebHistory(),
  routes: [
    {
      path: '/',
      name: '首页',
      redirect: '/home'
    },
    {
      path: '/home',
      name: '首页',
      component: Home
    },
    {
      path: '/news',
      name: '新闻',
      component: News
    },
    {
      path: '/about',
      name: 'Contact',
      component: About
    }
  ]
})

export default router

5.scr/app.vue

<template>
  <h1 class="title">Vue路由测试</h1>
  <div class="container">
    <RouterLink to="/home"  class="item"  >首页</RouterLink>
    <RouterLink to="/home"  class="item">产品</RouterLink>
    <RouterLink :to="{ path: '/news' }" class="item" >新闻</RouterLink>

  </div>
  <div class="routerbox">
    <RouterView></RouterView>
  </div>
</template>

<script  setup >
