路由,也就是导航栏那种的
<script src="vue.min.js"></script>
<script src="vue-router.min.js"></script>
<div id="app">
<h1>Hello App!</h1>
<p>
<!-- 使用 router-link 组件来导航. -->
<!-- 通过传入 `to` 属性指定链接. -->
<!-- <router-link> 默认会被渲染成一个 `<a>` 标签 -->
<router-link to="/">首页</router-link>
<router-link to="/student">会员管理</router-link>
<router-link to="/teacher">讲师管理</router-link>
</p>
<!-- 路由出口 -->
<!-- 路由匹配到的组件将渲染在这里 -->
<router-view></router-view>
</div>
<script>
// 1. 定义(路由)组件。
// 可以从其他文件 import 进来
const Welcome = { template: '<div>欢迎</div>' }
const Student = { template: '<div>student list</div>' }
const Teacher = { template: '<div>teacher list</div>' }
// 2. 定义路由
// 每个路由应该映射一个组件。
const routes = [
{ path: '/', redirect: '/welcome' }, //设置默认指向的路径
{ path: '/welcome', component: Welcome },
{ path: '/student', component: Student },
{ path: '/teacher', component: Teacher }
]
// 3. 创建 router 实例,然后传 `routes` 配置
const router = new VueRouter({
routes // (缩写)相当于 routes: routes
})
// 4. 创建和挂载根实例。
// 从而让整个应用都有路由功能
const app = new Vue({
el: '#app',
router
})
// 现在,应用已经启动了!
</script>
