Vue-router2.0基础实践

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");
