Basic use of VueRouter routing

Basic use of VueRouter routing

step

1. Prepare components
   .

<template>
	<h2>about</h2>
</template>![请添加图片描述](https://img-blog.csdnimg.cn/f0f65fb6e22046a397fa538ee311a679.png)


<script>
	export default {
		name: 'About'
	}
</script>

<style>
</style>

<template>
	<h2>home</h2>
</template>

<script>
	export default {
		name: 'Home'
	}
</script>

<style>
</style>

2. import vue-router

Now the default version of vue-router is 4, which can only be used in vue3. If you want to use it in vue2, you need to specify the version of vue-router as @3

Open a terminal and install

npm i vue-router@3

Vue-router is equivalent to a plug-in, which needs to be referenced. open main.js

import Vue from 'vue'
import App from './App.vue'
// 引入VueRouter
import VueRouter from 'vue-router'
// 引入路由器
import router from './router'
Vue.config.productionTip = false

// 应用插件
Vue.use(VueRouter)

new Vue({
    
    
  render: h => h(App),
  router
}).$mount('#app')

3. Define routing rules and create routing objects

// 该文件专门用于创建整个应用的路由器
import VueRouter from 'vue-router'
// 引入组件
import About from '../components/About'
import Home from '../components/Home'

// 创建并暴露一个路由器
export default new VueRouter({
    
    
	routes: [
		{
    
    
			path:'/about',
			component:About
		},
		{
    
    
			path:'/home',
			component:Home
		},
	]
})

4. router-link

<router-link class="list-group-item" active-class="active" to="/about">About</router-link>
<router-link class="list-group-item" active-class="active" to="/home">Home</router-link>

5. router-view display page

<!-- 指定组件呈现位置 -->
<router-view></router-view>
