1.路由：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<a></a>
<div id='app'>
<!--1.-->
<router-link to='/home'>首页</router-link>
<router-link to='/user'>用户页</router-link>
<!-- 盛放链接对应的内容-->
<router-view></router-view>
</div>
<script src='js/vue.js'></script>
<script src='js/vue-router.js'></script>
<script>
//2.创建组件
var Home={
template:`
<h1>这是首页</h1>
`
}
var User={
template:`
<h1>这是用户页</h1>
`
}
//3.配置路由
const routes=[
{path:'/home',component:Home},
{path:'/user',component:User}
]
//4.创建路由实例
const router=new VueRouter({
routes:routes
})
//5.路由实例挂载到vue实例上
new Vue({
el:'#app',
router:router
})
2.路由的嵌套：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<a></a>
<div id='app'>
<!--1.-->
<router-link to='/home'>首页</router-link>
<router-link to='/user'>用户页</router-link>
<!-- 盛放链接对应的内容-->
<router-view></router-view>
</div>
<script src='js/vue.js'></script>
<script src='js/vue-router.js'></script>
<script>
//2.创建组件
var Home={
template:`
<h1>这是首页</h1>
`
}
var User={
template:`
<h1>这是用户页</h1>
`
}
//3.配置路由
const routes=[
{path:'/home',component:Home},
{path:'/user',component:User}
]
//4.创建路由实例
const router=new VueRouter({
routes:routes
})
//5.路由实例挂载到vue实例上
new Vue({
el:'#app',
router:router
})
3.新学指令

v-text
v-once
v-pre
v-cloak
