vue-router菜鸟进阶！(嵌套路由VS命名路由)

嵌套路由

一个被渲染组件可以包含自己的嵌套< router-view >。

要在嵌套的出口中渲染组件，需要在VueRouter的参数中使用children配置：

<script src="https://unpkg.com/vue/dist/vue.js"></script>
<script src="https://unpkg.com/vue-router/dist/vue-router.js"></script>

<div id="app">
<p>
<router-link to="/user/foo">/user/foo</router-link>
<router-link to="/user/foo/profile">/user/foo/profile</router-link>
<router-link to="/user/foo/posts">/user/foo/posts</router-link>
</p>
<router-view></router-view>
</div>

const User = {
template: `
<div class="user">
<h2>User {{ $route.params.id }}</h2>
<router-view></router-view>
</div>
`
}

const UserHome = { template: '<div>Home</div>' }
const UserProfile = { template: '<div>Profile</div>' }
const UserPosts = { template: '<div>Posts</div>' }

const router = new VueRouter({
routes: [
{ path: '/user/:id', component: User,
children: [
// UserHome will be rendered inside User's <router-view>
// when /user/:id is matched
{ path: '', component: UserHome },

// UserProfile will be rendered inside User's <router-view>
// when /user/:id/profile is matched
{ path: 'profile', component: UserProfile },

// UserPosts will be rendered inside User's <router-view>
// when /user/:id/posts is matched
{ path: 'posts', component: UserPosts }
]
}
]
})

const app = new Vue({ router }).$mount('#app')

要注意，以 / 开头的嵌套路径会被当作根路径。 这让你充分的使用嵌套组件而无须设置嵌套的路径。

命名路由

有时候，通过一个名称来标识一个路由显得更方便一些，特别是在链接一个路由，或者是执行一些跳转的时候。可以在创建Router实例的时候，在routes配置中给某个路由设置名称。

const router = new VueRouter({
routes: [
{
path: '/user/:user:id',
name: 'user',
component: User
}
]
})

要链接到一个命名路由，可以给router-link的to属性传一个对象：

<router-link :to="{ name: 'user', params: { userId: 123 }}">User</router-link>

跟代码调用 router.push()是一回事：

router.push({ name: 'user', params: { userId: 123 }})

这两种方式都会把路由导航到/user/123路径。

For example:

import Vue from 'vue'
import VueRouter from 'vue-router'

Vue.use(VueRouter)

const Home = { template: '<div>This is Home</div>' }
const Foo = { template: '<div>This is Foo</div>' }
const Bar = { template: '<div>This is Bar {{ $route.params.id }}</div>' }

const router = new VueRouter({
mode: 'history',
base: __dirname,
routes: [
{ path: '/',  name: 'home', component: Home },
{ path: '/foo', name: 'foo', component: Foo },
{ path: '/bar', name: 'bar', component: Bar }
]
})

new Vue({
router,
template: `
<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-l
4000
ink></li>
</ul>
<router-view class="view"></router-view>
</div>
`
}).$.mount('#app')
