本文主要和大家介绍vue router 动态路由和嵌套路由，详细的介绍了动态路由和嵌套路由的使用方法，有兴趣的可以了解一下，希望能帮助到大家。
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> <p 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> </p> </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>
<p 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>
</p>
</template>

import Router from 'vue-router'

Vue.use(Router)
export default new Router({

})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。
