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> <!-- 头部导航 --> ... <main> <!-- 左侧导航 --> <div> ... </div> <!-- 右侧主内容区 --> <div > <!-- 视图 --> <router-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> <!-- element步骤组件 --> <el-steps :space="200" :active="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> <!-- 步骤组件 --> <el-steps :space="200" :active="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></router-view> <div> <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,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> <!-- element表单组件 --> <el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-position="top"> <!--
