9、SPA单页应用（一级路由）

本例主要采用路由配置，实现上面导航不动，下面页面可跳转的功能

一个vue的单页应用（一级路由）的脚手架程序构建
1.命令行先进入某个目录如D:\VueStudy
2.创建项目: vue init webpack demo
3.进入demo目录安装依赖：npm install
4.修改config目录下index.js的dev端口为80
5.运行：npm run dev，打开http://localhost，看到Vue主页logo即成功

• index.js

import Vue from 'vue'
import Router from 'vue-router'
Vue.use(Router)
export default new Router({
mode:"history",
//使上面的/后面没有#号如：
routes: [
{
path: '/',
name: 'Index',
component: resolve=>require(['../components/Index.vue'],resolve)
},
{
path: '/message',
name: 'Message',
component: resolve=>require(['../components/Message.vue'],resolve)
},
]
})
