接上一章vue入門 | 使用vue.js2.0 + ElementUI開(kāi)發(fā)后臺(tái)管理系統(tǒng)詳細(xì)教程（一）
在線demo
源碼
1. 引入路由工具vue-router，切換視圖
#安裝vue-router
npm install vue-router --save
2. 使用vue-router
|-- main.js
import Vue from 'vue'
import App from './App'
import VueRouter from 'vue-router'
import routeConfig from './router-config' // 引入router-config.js文件
//加載路由中間件
Vue.use(VueRouter)
//定義路由
const router = new VueRouter({
routes: routeConfig
})
new Vue({
router,
store,
el: "#app",
render: h => h(App)
})
3. 配置路由
在src目錄下新建router-config.js揭措，在router-cinfig.js中里面配置路由
// 引入組件
import activePublic from './page/activePublic/index.vue'
export default [
{
// 配置路由市埋，當(dāng)路徑為'/activePublic',使用組件activePublic
path:'/activePublic',component:activePublic,
}
]
4. 使用路由
|--app.vue
<template>
<div id="app">
<!-- 頭部導(dǎo)航 -->
...
<main>
<!-- 左側(cè)導(dǎo)航 -->
<div class="main-left">
...
</div>
<!-- 右側(cè)主內(nèi)容區(qū) -->
<div class="main-right" >
<!-- 視圖 -->
<router-view class="view"></router-view>
</div>
</main>
</div>
</template>
5. 打開(kāi)activePublic/index.vue文件，在頁(yè)面隨便寫點(diǎn)東西互墓，測(cè)試一下必尼，路由是否配置成功
<template>
<div class="activePublic ">
<!-- element步驟組件 -->
<el-steps :space="200" :active="step" class="step">
<el-step title="活動(dòng)信息" description=""></el-step>
<el-step title="報(bào)名簽到" description=""></el-step>
<el-step title="分享設(shè)置" description=""></el-step>
<el-step title="個(gè)性設(shè)置" description=""></el-step>
</el-steps>
</template>
6. 啟動(dòng)項(xiàng)目npm run dev，看到如下頁(yè)面篡撵，說(shuō)明路由配置成功
step1.png
7. 接下來(lái)判莉，在activePublic/index.vue直接調(diào)用element-ui組件，完成活動(dòng)發(fā)布的首頁(yè)育谬，完成好的代碼如下
|-- activePublic/index.vue
<template>
<div class="activePublic ">
<!-- 步驟組件 -->
<el-steps :space="200" :active="step" class="step">
<el-step title="活動(dòng)信息" description=""></el-step>
<el-step title="報(bào)名簽到" description=""></el-step>
<el-step title="分享設(shè)置" description=""></el-step>
<el-step title="個(gè)性設(shè)置" description=""></el-step>
</el-steps>
<!-- 視圖 -->
<router-view class="view"></router-view>
<div class="but-group">
<el-button >預(yù)覽</el-button>
<el-button >上一步</el-button>
<el-button type="primary">下一步</el-button>
<el-button type="primary">發(fā)布活動(dòng)</el-button>
</div>
</div>
</template>
上面這個(gè)頁(yè)面又出現(xiàn)了一個(gè)router-view券盅，為什么要這樣放呢？因?yàn)閟tep1膛檀、step2锰镀、step3、step4四個(gè)頁(yè)面都含有頂部的"步驟"組件宿刮，所以這里把step1/2/3/4單獨(dú)提出來(lái)放在4個(gè)頁(yè)面中
8. 在router-config.js文件中配置二級(jí)路由
|-- router-config.js
import activePublic from './page/activePublic/index.vue'
<!-- 引入子頁(yè)面 -->
import step1 from './page/activePublic/step1.vue'
import step2 from './page/activePublic/step2.vue'
import step3 from './page/activePublic/step3.vue'
import step4 from './page/activePublic/step4.vue'
export default [
{
path:'/activePublic',component:activePublic,
// 配置子路由
children:[
// 路徑為'/activePublic'互站，使用組件step1
{ path: '' , component: step1 },
// 路徑為'/activePublic/step1'，使用組件step1
{ path: 'step1', component: step1 },
// 路徑為'/activePublic/step2'僵缺，使用組件step2
{ path: 'step2', component: step2 },
{ path: 'step3', component: step3 },
{ path: 'step4', component: step4 }
]
}
]
9. 重新啟動(dòng)項(xiàng)目cnpm run dev,在瀏覽器中默認(rèn)路徑為http://localhost:8080/#/activePublic,根據(jù)我們?cè)O(shè)置的路由規(guī)則胡桃，就會(huì)顯示step1.vue頁(yè)面中的內(nèi)容,接著完成step1.vue，代碼如下磕潮，參考element表單組件
|-- step1.vue
<template>
// TODO:這個(gè)頁(yè)面有一個(gè)不足之處翠胰，時(shí)間選擇器組件容贝，表單驗(yàn)證出錯(cuò)，這是element組件的問(wèn)題之景，留給大家自己去完善
<div class="step1">

這個(gè)頁(yè)面的大部分是使用的element組件，請(qǐng)自行對(duì)照官網(wǎng)實(shí)現(xiàn)澈蚌。在這個(gè)頁(yè)面中封裝了一個(gè)二級(jí)地址選擇插件摹芙，稍后會(huì)專門寫一篇文章，詳細(xì)介紹如何封裝組件宛瞄，先為大家奉上地址選擇器源碼浮禾。
10. 重新啟動(dòng)項(xiàng)目,npm run dev,檢查頁(yè)面上的功能是否都已經(jīng)實(shí)現(xiàn)，是否有報(bào)錯(cuò)份汗，如果有解決不了的bug盈电，歡迎留言咨詢。
