  1. 基础用法:
<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="/foo">Go to Foo</router-link>
        <router-link to="/bar">Go to Bar</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>

<template id='foo'>
    <p>this is foo!</p>
</template>
<template id='bar'>
    <p>this is bar!</p>
</template>
// 1. 定义(路由)组件。  
// 可以从其他文件 import 进来  
const Foo = { template:'#foo' };  
const Bar = { template:'#bar' };  
// 2. 定义路由  
// 每个路由应该映射一个组件。 其中"component" 可以是  
// 通过 Vue.extend() 创建的组件构造器,  
// 或者,只是一个组件配置对象。  
const routes = [  
    { path: '/foo', component: Foo },  
    { path: '/bar', component: Bar }  
];  
// 3. 创建 router 实例,然后传 `routes` 配置  
// 你还可以传别的配置参数, 不过先这么简单着吧。  
const router = new VueRouter({ routes:routes });  
// 4. 创建和挂载根实例。  
// 记得要通过 router 配置参数注入路由,  
// 从而让整个应用都有路由功能  
const app = new Vue({ router:router }).$mount('#app');  
  1. 动态路由匹配:
<div id="app">  
    <h1>Hello App!</h1>  
    <p>  
        <router-link to="/user/foo/post/123">Go to Foo</router-link>  
        <router-link to="/user/bar/post/456">Go to Bar</router-link>  
    </p>  
    <router-view></router-view>  
</div>  
  
<template id='user'>  
    <p>User:{{ $route.params.id }},Post:{{$route.params.post_id}}</p>  
</template>  
// 1. 定义组件。  
const User = {  
    template:'#user',  
    watch:{  
        '$route'(to,from){  
            console.log('从'+from.params.id+'到'+to.params.id);  
        }  
    }  
};  
// 2. 创建路由实例 (可设置多段路径参数)  
const router = new VueRouter({  
    routes:[  
        { path:'/user/:id/post/:post_id',component:User }  
    ]  
});  
//3. 创建和挂载根实例  
const app = new Vue({ router:router }).$mount('#app');  
  1. 嵌套路由:
<div id="app">  
    <h1>Hello App!</h1>  
    <p>  
        <router-link to="/user/foo">Go to Foo</router-link>  
        <router-link to="/user/foo/profile">Go to profile</router-link>  
        <router-link to="/user/foo/posts">Go to posts</router-link>  
    </p>  
    <router-view></router-view>  
</div>  
  
<template id='user'>  
    <div>  
        <h2>User:{{ $route.params.id }}</h2>  
        <router-view></router-view>  
    </div>  
</template>  
  
<template id="userHome">  
    <p>主页</p>  
</template>  
  
<template id="userProfile">  
    <p>概况</p>  
</template>  
  
<template id="userPosts">  
    <p>登录信息</p>  
</template>  
// 1. 定义组件。  
const User = {  
    template:'#user'  
};  
const UserHome = {  
    template:'#userHome'  
};  
const UserProfile = {  
    template:'#userProfile'  
};  
const UserPosts = {  
    template:'#userPosts'  
};  
// 2. 创建路由实例  
const router = new VueRouter({  
    routes:[  
        { path:'/user/:id', component:User,  
            children:[  
                // 当 /user/:id 匹配成功,  
                // UserHome 会被渲染在 User 的 <router-view> 中  
                { path: '', component: UserHome},  
                // 当 /user/:id/profile 匹配成功,  
                // UserProfile 会被渲染在 User 的 <router-view> 中  
                { path:'profile', component:UserProfile },  
                // 当 /user/:id/posts 匹配成功  
                // UserPosts 会被渲染在 User 的 <router-view> 中  
                { path: 'posts', component: UserPosts }  
            ]  
        }  
    ]  
});  
//3. 创建和挂载根实例  
const app = new Vue({ router:router }).$mount('#app');  
  1. 编程式路由:
<div id="app">  
    <h1>Hello App!</h1>  
    <p>  
        <router-link to="/user/foo">Go to Foo</router-link>  
    </p>  
    <router-view></router-view>  
</div>  
  
<template id='user'>  
    <h2>User:{{ $route.params.id }}</h2>  
</template>  
  
<template id="register">  
    <p>注册</p>  
</template>  
// 1. 定义组件。  
const User = {  
    template:'#user'  
};  
const Register = {  
    template:'#register'  
};  
// 2. 创建路由实例  
const router = new VueRouter({  
    routes:[  
        { path:'/user/:id', component:User },  
        { path:'/register', component:Register }  
    ]  
});  
//3. 创建和挂载根实例  
const app = new Vue({ router:router }).$mount('#app');  
  
//4.router.push(location)  
router.push({ path: 'register', query: { plan: 'private' }});  
  1. 命名路由:
<div id="app">  
    <h1>Named Routes</h1>  
    <p>Current route name: {{ $route.name }}</p>  
    <ul>  
        <li><router-link :to="{ name: 'home' }">home</router-link></li>  
        <li><router-link :to="{ name: 'foo' }">foo</router-link></li>  
        <li><router-link :to="{ name: 'bar', params: { id: 123 }}">bar</router-link></li>  
    </ul>  
    <router-view class="view"></router-view>  
</div>  
  
<template id='home'>  
    <div>This is Home</div>  
</template>  
  
<template id='foo'>  
    <div>This is Foo</div>  
</template>  
  
<template id='bar'>  
    <div>This is Bar {{ $route.params.id }}</div>  
</template>  
const Home = { template: '#home' };  
const Foo = { template: '#foo' };  
const Bar = { template: '#bar' };  
  
const router = new VueRouter({  
    routes: [  
        { path: '/', name: 'home', component: Home },  
        { path: '/foo', name: 'foo', component: Foo },  
        { path: '/bar/:id', name: 'bar', component: Bar }  
    ]  
});  
  
new Vue({ router:router }).$mount('#app');  
  1. 命名视图:
<div id="app">  
    <router-link to="/">Go to Foo</router-link>  
    <router-view class="view one"></router-view>  
    <router-view class="view two" name="a"></router-view>  
    <router-view class="view three" name="b"></router-view>  
</div>  
  
<template id='foo'>  
    <div>This is Foo</div>  
</template>  
  
<template id='bar'>  
    <div>This is Bar {{ $route.params.id }}</div>  
</template>  
  
<template id='baz'>  
    <div>This is baz</div>  
</template>  
const Foo = { template: '#foo' };  
const Bar = { template: '#bar' };  
const Baz = { template: '#baz' };  
  
const router = new VueRouter({  
    routes: [  
        {  
            path: '/',  
            components: {  
                default:Foo,  
                a:Bar,  
                b:Baz  
            }  
        }  
    ]  
});  
  
new Vue({ router:router }).$mount('#app');
