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');
2)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');
3)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');
4)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' }});

5)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');
6)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');
