路由：vue-router 帶三方工具庫
創(chuàng)建單頁面應用 spa (single page application)
通過不同的URL訪問不同的頁面
下載：
npm install vue
npm install vue-router
1.制作一個簡單的路由
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style>
/*
.router-link-active{
text-decoration: none;
background: orange;
color:black;
}
*/
.active{
text-decoration: none;
background: orange;
color:black;
}
</style>
</head>
<body>
<div class="itany">
<!-- 1.-->
<router-link to='/index'>首頁</router-link>
<router-link to='/about'>詳情頁</router-link>
<!-- 盛放導航內(nèi)容-->
<router-view></router-view>
</div>
<script src="vue.js"></script>
<script src="vue-router.js"></script>
<script>
// 2.創(chuàng)建組件
var Index={
template:`
<h1>我是首頁</h1>
`
}
var About={
template:`
<h1>我是詳情頁</h1>
`
}
// 3.配置路由
const routes=[
{path:'/',component:Index},
{path:'/index',component:Index},
{path:'/about',component:About}
]
// 4.創(chuàng)建一個路由實例
const router=new VueRouter({
routes:routes,
linkActiveClass:'active'
})
// 5.把路由實例掛載到vue實例上
new Vue({
el:'.itany',
router:router
})
</script>
</body>
</html>
注釋：點擊之后可跳轉(zhuǎn)，并出現(xiàn)自己所設置的樣式
2.路由的傳參:
查詢字符串：
/user/regist?uname=jack&&upwd=123
接收：{{
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>路由的傳參</title>
</head>
<body>
<div id="app">
<router-link to="/index">首頁</router-link>
<router-link to="/about">用戶頁</router-link>
<router-view></router-view>
</div>
<script src="vue.js"></script>
<script src="vue-router.js"></script>
<script>
// 2.創(chuàng)建組件
var Index={
template:`
<h1>這是首頁</h1>
`
}
var About={
template:`
<div>
<h1>這是用戶頁</h1>
<ul>
<li>
<router-link to="/about/user?uname=jack&upwd=123">注冊</router-link>
</li>
<li>
<router-link to='/about/login/rose/456'>登錄</router-link>
</li>
</ul>
<router-view></router-view>
</div>
`
}
var User={
template:`
<div>
<h3>我是注冊頁</h3>
<a href="#">{{$route.query}}</a>
<ul>
<li>{{$route.query.uname}}</li>
<li>{{$route.query.upwd}}</li>
</ul>
</div>
`
}
var Login={
template:`
<div>
<h3>我是登錄頁</h3>
<a href="#">{{$route.params}}</a>
<ul>
<li>{{$route.params.userName}}</li>
<li>{{$route.params.password}}</li>
</ul>
</div>
`
}
// 3、配置路由
const routes=[
{path:'/',component:Index}, {path:'/index',component:Index},
{
path:'/about',
component:About,
children:[
{path:'user',component:User},
{path:'login/:userName/:password',component:Login},
]
},
]
// 4.創(chuàng)建路由實例
const router=new VueRouter({
routes:routes
})
// 5.
new Vue({
el:'#app',
router:router//注冊路由
})
</script>

3.路由的嵌套
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>路由的嵌套</title>
</head>
<body>
<div id="app">
<router-link to="/index">首頁</router-link>
<router-link to="/about">用戶頁</router-link>
<router-view></router-view>
</div>
<script src="vue.js"></script>
<script src="vue-router.js"></script>
<script>
// 2.創(chuàng)建組件
var Index={
template:`
<h1>這是首頁</h1>

}
var About={
template:`

<h1>這是用戶頁</h1>
<ul>

4.axios
vue中的ajax 插件
下載axios:
npm install axios
1.0 vue-resource
2.0 axios
安裝http-server
npm install http-server -g
使用http-server 開啟一個服務器
