深入理解vue路由的使用

<script src="js/vue.js"></script>
<script src="js/vue-router.js"></script>

然后创建两个组件构造器Home和About
var Home = Vue.extend({
 template: '<div><h1>Home</h1><p>{{msg}}</p></div>',
 data: function() {
 return {
  msg: 'Hello, vue router!'
 }
 }
})

var About = Vue.extend({
 template: '<div><h1>About</h1><p>This is the tutorial about vue-router.</p></div>'
})

var router = new VueRouter()

router.map({
 '/home': { ponent: Home },
 '/about': { ponent: About }
})

<div class="list-group">
 <a class="list-group-item" v-link="{ path: '/home'}">Home</a>
 <a class="list-group-item" v-link="{ path: '/about'}">About</a>
</div>

<router-view></router-view>

var App = Vue.extend({})
router.start(App, '#app')

npm run demo01-dev

npm run demo01-build

router.redirect({
 '/': '/home'
})

<template id="home">
 <div>
 <h1>Home</h1>
 <p>{{msg}}</p>
 </div>
 <div>
 <ul class="nav nav-tabs">

var Message = Vue.extend({

router.map({

 ponent: Home,
 // 定义子路由

<!-- 字面量路径 -->
<a v-link="'home'">Home</a>

<!-- 效果同上 -->
