VueRouter的基本使用_vue中router文件的

router文件夹中index.js文件

import Vue from 'vue';
import VueRouter from 'vue-router';
 
// import Home from '../components/Home';
// import About from '../components/About';
// import HelloWorld from '../components/HelloWorld';
// import User from '../components/User'
 
// 路由懒加载导入
const Home = ()=>import('../components/Home');
const About = ()=>import('../components/About');
const User = ()=>import('../components/User');
// const HelloWorld = ()=>import('../components/HelloWorld');
const HomeMessage = ()=>import('../components/HomeMessage');
const HomeProfile = ()=>import('../components/HomeProfile');
const Profile = ()=>import('../components/Profile')
 
// 1.使用Vue.use(插件),安装插件
Vue.use(VueRouter)
// 2.创建VueRouter对象
const routes=[
	{
		path:'/',
		// redirect重定向
		redirect:'/home'
	},
	{
		path:'/home',
		component:Home,
		redirect:'/message',
		meta:{
			title:"首页"
		},
		children:[
			{
				path:'/message',
				component:HomeMessage
			},
			{
				path:'/profile',
				component:HomeProfile
			}
		]
	},
	{
		path:'/about',
		component:About,
		meta:{
			title:"关于"
		},
	},
	
	{
		path:'/user/:userId',
		component:User,
		meta:{
			title:"用户"
		},
	},
	{
		path:'/profile',
		component:Profile,
		meta:{
			title:"简介"
		},
	}
 
];
const router=new VueRouter({
	// 这个自定义的名字,是可以的,但是这里由于是使用了es6 的语法糖的形式,将前面相同给省略了, 但是如果省略的话,就必须要求是一致的 routes:routes (没有引号)
	// routes:routers,
	routes,
	mode:'history',
	linkActiveClass:'active'
	
});
// to:即将跳转进入的路由对象;from:当前导航即将离开的路由对象;next:调用该方法后,才能进入下一个钩子
// 前置守卫/回调(guard)
router.beforeEach((to,from,next)=>{
	// 从from跳转到to
	document.title=to.matched[0].meta.title;
	console.log(to)
	next()
})
// 3.导出Router
export default router

app.vue文件
