本文主要参考:https://router.vuejs.org/zh-cn/essentials/nested-routes.html
本文的阅读前提是已经能够搭建一个vue前台程序并且运行。如果还么有搭建可以参考文章:

好,下面上货。
首先介绍一下动态路由。
动态路由按照我的理解,就是说能够进行页面的跳转,比如说:下面的这个页面中:
- <template>
- <div id="app">
- <header>
- <router-link to="/">/</router-link>
- <router-link to="/hello">/hello</router-link>
- <router-link to="/cc">/cc</router-link>
- </header>
- <router-view style="border: 1px solid red"></router-view>
- </div>
- </template>
如果点击了/hello,那么在router-view中就会加载对应的模块,也就是在路由中设置的模块。
- import Vue from 'vue'
- import Router from 'vue-router'
- import Hello from '@/components/Hello'
- import Foo from '@/components/Foo'
- import Foo2 from '@/components/Foo2'
- import Foo3 from '@/components/Foo3'
- Vue.use(Router)
- export default new Router({
- routes: [
- {path: '/', redirect: '/hello'},
- {
- path: '/hello',
- component: Hello,
- children: [
- {path: '/hello/foo', component: Foo},
- {path: '/hello/foo2', component: Foo2},
- {path: '/hello/foo3', component: Foo3}
- ]
- },
- {
- path: '/cc',
- name: 'Foo',
- component: Foo
- }
- ]
- })
也就是说,会跳转到Hello和Foo这两个组件。
那么嵌套路由是什么意思呢,最开始我以为的是这样:/hello/foo 和/hello/foo2这两个路由可以简写成嵌套路由,其实不是的。嵌套路由只的是,在子组件中再次嵌套组件。然后在使用路由进行跳转,这样跳转的时候,变化的就只有子组件,而外边的父组件没有变化。
下面我把完整的例子放出来,看一下:
App.vue
- <template>
- <div id="app">
- <header>
- <router-link to="/">
- /
- </router-link>
- <router-link to="/hello">
- /hello
- </router-link>
- <router-link to="/cc">
- /cc
- </router-link>
- </header>
- <router-view style="border: 1px solid red">
- </router-view>
- </div>
- </template>
- <script>
- export
- default {
- name:
- 'app'
- }
- </script>
- <style>
- #app { font-family: 'Avenir', Helvetica, Arial, sans-serif; -webkit-font-smoothing:
- antialiased; -moz-osx-font-smoothing: grayscale; text-align: center; color:
- #2c3e50; margin-top: 60px; }
- </style>
Foo.vue
- <template>
- <div>
- <h1>3434234343</h1>
- </div>
- </template>
- <script>
- export default {
- name: 'Foo',
- data () {
- return {
- }
- }
- }

- <style scoped>
- h1, h2 {
- font-weight: normal;
- }
- ul {
- list-style-type: none;
- padding: 0;
- }
- li {
- display: inline-block;
- margin: 0 10px;
- }
- a {
- color: #42b983;
- }
- </style>
Foo2.vue
- <template>
- <div>
- <h1>this is Foo2</h1>

- </style>
Foo3.vue
- <template>
- <div>
- <h1>this is foo3</h1>
- </div>

- }
- }
- </script>
- <!-- Add "scoped" attribute to limit CSS to this component only -->
- <style scoped>
- h1, h2 {
- font-weight: normal;
- }
- ul {
- list-style-type: none;
- padding: 0;
- }
- li {
- display: inline-block;
- margin: 0 10px;
- }
- a {
- color: #42b983;
- }
- </style>
Hello.vue
- <template>
- <div class="hello">
- <h1>{{ msg }}</h1>

路由:
- import Vue from 'vue'
- import Router from 'vue-router'
- import Hello from '@/components/Hello'
- import Foo from '@/components/Foo'
- import Foo2 from '@/components/Foo2'
- import Foo3 from '@/components/Foo3'
- Vue.use(Router)
- export default new Router({
- routes: [
- {path: '/', redirect: '/hello'},
- {
- path: '/hello',
- component: Hello,
- children: [
- {path: '/hello/foo', component: Foo},
- {path: '/hello/foo2', component: Foo2},
- {path: '/hello/foo3', component: Foo3}
- ]
- },
- {
- path: '/cc',
- name: 'Foo',
- component: Foo
- }
- ]
- })
需要注意的是仔细的看App.vue和Hello.vue中,都包含
我把页面截图一下:
这个界面,点击最上边的 / 或者/hello 或者/cc的时候,发生变化的是红色路由中的内容。当点击/hello/foo /hello/foo2 /hello/foo3 的时候,发生变化的是下面蓝色路由中的内容。
这样就和我们平时应用十分的相似了。最外层于有变化,或者局部有变化,但是不想全局的发生改变。
同时,这样也符合了模块化,各个模块分别在不同的模块中。
