路由组件

Home.vue

<template>
	<div>
		<h2>Home组件内容</h2>
		<div>
			<ul class="nav nav-tabs">
				<li>
					<!-- 注意 to指向的是路由配置的children的某个路径,所以这里是 /home下的/XXX   -->
					<router-link class="list-group-item" active-class="active" to="/home/news">News</router-link>

Message.vue 略
New.vue 略

路由配置文件 router/index.js

// 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 '../pages/About'
import Home from '../pages/Home'
import News from '../pages/News'
import Message from '../pages/Message'

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

总结

需求

在home组件下存在new和message两个组件

1. 当点击home按钮时跳转到home组件
2. 当点击home组件里面的new组件时,展示new组件内容
3. 当点击home组件里面的message组件时,展示message组件内容

路由配置children

		{
			path:'/home',
			component:Home,
			children:[
				{
					path:'news',
					component:News,
				},
				{
					path:'message',
					component:Message,
				}
			]
		}

路径跳转

因为new和message包含在home组件中,所以路径跳转设置在Home组件中

<li>
	<!-- 注意 to指向的是路由配置的children的某个路径,所以这里是 /home下的/XXX   -->
	<router-link class="list-group-item" active-class="active" to="/home/news">News</router-link>
</li>
<li>
	<router-link class="list-group-item" active-class="active" to="/home/message">Message</router-link>
</li>
