使用vue.js2.0 + ElementUI开发后台管理系统详细教程（二）

在上篇文章给大家介绍了使用vue.js2.0+ElementUI开发后台管理系统详细教程（一）1.引入路由工

在上篇文章给大家介绍了使用vue.js2.0 + ElementUI开发后台管理系统详细教程（一）

1. 引入路由工具vue-router，切换视图

# 安装vue-router
cnpm install vue-router --save-dev

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
//加载路由中间件
Vue.use(VueRouter)
//定义路由
const router = new VueRouter({
 routes: routeConfig
})
new Vue({
 router,
 store,
 el: "#app",
 render: h => h(App)
})

3. 配置路由

在src目录下新建router-config.js，在router-cinfig.js中里面配置路由

// 引入组件
import activePublic from './page/activePublic/index.vue'
export default [
 {
 // 配置路由，当路径为'/activePublic',使用组件activePublic
 path:'/activePublic',component:activePublic,
 }
]

4. 使用路由

app.vue
<template>
 <div id="app">
 <!-- 头部导航 -->
 ...
 <main>
 <!-- 左侧导航 -->
 <div class="main-left">
 ...
 </div>
 <!-- 右侧主内容区 -->
 <div class="main-right" >
 <!-- 视图 -->
 <router-view class="view"></router-view>
 </div>
 </main>
 </div>
</template>

5. 打开activePublic/index.vue文件，在页面随便写点东西，测试一下，路由是否配置成功

<template>
 <div class="activePublic ">
 <!-- element步骤组件 -->
 <el-steps :space="200" :active="step" class="step">
 <el-step title="活动信息" description=""></el-step>
 <el-step title="报名签到" description=""></el-step>
 <el-step title="分享设置" description=""></el-step>
 <el-step title="个性设置" description=""></el-step>
 </el-steps>
</template>

6. 启动项目cnpm run dev，看到如下页面，说明路由配置成功

7. 接下来，在activePublic/index.vue直接调用element-ui组件，完成活动发布的首页，完成好的代码如下

activePublic/index.vue
<template>
 <div class="activePublic ">
 <!-- 步骤组件 -->
 <el-steps :space="200" :active="step" class="step">
 <el-step title="活动信息" description=""></el-step>
 <el-step title="报名签到" description=""></el-step>
 <el-step title="分享设置" description=""></el-step>
 <el-step title="个性设置" description=""></el-step>
 </el-steps>
 <!-- 视图 -->
 <router-view class="view"></router-view>
 <div class="but-group">
 <el-button >预览</el-button>
 <el-button >上一步</el-button>
 <el-button type="primary">下一步</el-button>
 <el-button type="primary">发布活动</el-button>
 </div>
 </div>
</template>

上面这个页面又出现了一个router-view，为什么要这样放呢？因为step1、step2、step3、step4四个页面都含有顶部的"步骤"组件，所以这里把step1/2/3/4单独提出来放在4个页面中

8. 在router-config.js文件中配置二级路由

router-config.js
import activePublic from './page/activePublic/index.vue'
<!-- 引入子页面 -->
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:[
 // 路径为'/activePublic'，使用组件step1
 { path: '' , component: step1 },
 // 路径为'/activePublic/step1'，使用组件step1
 { path: 'step1', component: step1 },
 // 路径为'/activePublic/step2'，使用组件step2
 { path: 'step2', component: step2 },
 { path: 'step3', component: step3 },
 { path: 'step4', component: step4 }
 ]
 }
]

9. 重新启动项目cnpm run dev,在浏览器中默认路径为http://localhost:8080/#/activePublic,根据我们设置的路由规则，就会显示step1.vue页面中的内容,接着完成step1.vue，代码如下，参考element表单组件

step1.vue

<template>
 // TODO:这个页面有一个不足之处，时间选择器组件，表单验证出错，这是element组件的问题，留给大家自己去完善
 <div class="step1">
 <!-- element表单组件 -->
 <el-form :model="ruleForm" class="demo-ruleForm" :rules="rules" ref="ruleForm" label-position="top">
 <!-- 表单项，prop属性表示要进行表单验证，验证规则对应为rules的属性name -->
 <el-form-item label="活动名称" prop="name">
 <el-input v-model="ruleForm.name" size="large"></el-input>
 </el-form-item>
 <el-form-item label="" prop="fenLei">
 <!-- 改装后的表单项，在标签栏添加了一个按钮 -->

这个页面的大部分是使用的element组件，请自行对照官网实现。在这个页面中封装了一个二级地址选择插件，稍后会专门写一篇文章，详细介绍如何封装组件，先为大家奉上地址选择器源码。

10. 重新启动项目,cnpm run dev,检查页面上的功能是否都已经实现，是否有报错，如果有解决不了的错误，欢迎留言咨询，我会第一时间为您解答。
