vue router学习之动态路由和嵌套路由详解
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 { } } } </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>
Foo2.vue
<template> <div> <h1>this is Foo2</h1> </div> </template> <script> export default { name: 'Foo2', data () { return { } } } </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>
Foo3.vue
<template> <div> <h1>this is foo3</h1> </div> </template> <script> export default { name: 'Foo3', data () { return { } } } </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> <h2>Essential Links</h2> <ul> <li><a href="https://vuejs.org" rel="external nofollow" target="_blank">Core Docs</a></li> <li><a href="https://forum.vuejs.org" rel="external nofollow" target="_blank">Forum</a></li> <li><a href="https://gitter.im/vuejs/vue" rel="external nofollow" target="_blank">Gitter Chat</a></li> <li><a href="https://twitter.com/vuejs" rel="external nofollow" target="_blank">Twitter</a></li> <br> <li><a href="http://vuejs-templates.github.io/webpack/" rel="external nofollow" target="_blank">Docs for This Template</a></li> </ul> <h2>Ecosystem</h2> <ul> <li><a href="http://router.vuejs.org/" rel="external nofollow" target="_blank">vue-router</a></li> <li><a href="http://vuex.vuejs.org/" rel="external nofollow" target="_blank">vuex</a></li> <li><a href="http://vue-loader.vuejs.org/" rel="external nofollow" target="_blank">vue-loader</a></li> <li><a href="https://github.com/vuejs/awesome-vue" rel="external nofollow" target="_blank">awesome-vue</a></li> </ul> <div> <router-link to="/hello/foo">/hello/foo</router-link> <router-link to="/hello/foo2">/hello/foo2</router-link> <router-link to="/hello/foo3">/hello/foo3</router-link> </div> <router-view style="border: solid 1px blue"></router-view> </div> </template> <script> export default { name: 'hello', data () { return { msg: 'Welcome to Your Vue.js App' } } } </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>
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<router-view></router-view>,但是他们的作用不同,App.vue是顶层路由,指的是组外层的路由,Hello.vue中的是嵌套路由,负责显示子组件。
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。
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持我们。
