本文主要和大家介紹vue router 動態路由和嵌套路由,詳細的介紹了動態路由和嵌套路由的使用方法,有興趣的可以了解一下,希望能幫助到大家。
先介紹一下動態路由。
動態路由依照我的理解,就是說能夠進行頁面的跳轉,比如說:下面的這個頁面中:
<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>
如果點擊了/hello,那麼在router-view中就會載入對應的模組,也就是在路由中設定的模組。
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 } ] })
也就是說,會跳到Hello和Foo這兩個元件。
那麼嵌套路由是什麼意思呢,最開始我以為的是這樣:/hello/foo 和/hello/foo2這兩個路由可以簡寫成嵌套路由,其實不是的。嵌套路由隻的是,在子元件中再次嵌套元件。然後在使用路由進行跳轉,這樣跳轉的時候,變化的就只有子組件,而外邊的父組件沒有變化。
下面我把完整的例子放出來,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> <script> export default { name: 'app' } </script>
Foo.vue
<template> <p> <h1>3434234343</h1> </p> </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> <p> <h1>this is Foo2</h1> </p> </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> <p> <h1>this is foo3</h1> </p> </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> <p 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> <p> <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> </p> <router-view style="border: solid 1px blue"></router-view> </p> </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 } ] })
要注意的是仔細的看App.vue和Hello.vue中,都包含975b587bf85a482ea10b0a28848e78a4dd6e4ababe59793a4ac75fb9e5c5550e,但是他們的作用不同,App.vue是頂層路由,指的是組外層的路由,Hello.vue中的是嵌套路由,負責顯示子組件。
我把頁面截圖一下:
這個介面,點擊最上邊的/ 或/hello 或/cc的時候,改變的是紅色路由中的內容。當點擊/hello/foo /hello/foo2 /hello/foo3 的時候,發生變化的是下面藍色路由中的內容。
這樣就和我們平常應用十分的相似了。最外層於有變化,或局部有變化,但是不想全域的發生改變。
同時,這樣也符合了模組化,各個模組分別在不同的模組中。
