最近初学vue，试着做一个小项目熟悉语法与思想，其中使用elemen-ui的导航栏做路由跳转切换页面。下面记录一下学习过程

element-ui引入vue项目的用法参考element官网

首先复制官网的例子，在这基础上再修改成我们想要的样子。


<el-menu :default-active="activeIndex" class="el-menu-demo" mode="horizontal" @select="handleSelect">
 <el-menu-item index="1">处理中心</el-menu-item>
 <el-submenu index="2">
 <template slot="title">我的工作台</template>
 <el-menu-item index="2-1">选项1</el-menu-item>
 <el-menu-item index="2-2">选项2</el-menu-item>
 <el-menu-item index="2-3">选项3</el-menu-item>
 <el-submenu index="2-4">
  <template slot="title">选项4</template>
  <el-menu-item index="2-4-1">选项1</el-menu-item>
  <el-menu-item index="2-4-2">选项2</el-menu-item>
  <el-menu-item index="2-4-3">选项3</el-menu-item>
 </el-submenu>
 </el-submenu>
 <el-menu-item index="3" disabled>消息中心</el-menu-item>
 <el-menu-item index="4"><a href="https://www.ele.me" rel="external nofollow" target="_blank">订单管理</a></el-menu-item>
</el-menu>
<script>
 export default {
 data() {
  return {
  activeIndex: '1'
  };
 },
 methods: {
  handleSelect(key, keyPath) {
  console.log(key, keyPath);
  }
 }
 }
</script>

属性：

* default-active：表示当前active的菜单项的编号

* index：类型为字符串，在每一个el-menu-item组件上都有一个编号，给default-active标记

使用菜单栏进行路由跳转：


<el-menu :default-active="this.$router.path" router mode="horizontal">
 <el-menu-item v-for="(item,i) in navList" :key="i" :index="item.name">
  {{ item.navItem }}
 </el-menu-item>
</el-menu>

数据：


data() {
  return {
  navList:[
   {name:'/findProject',navItem:'发现项目'},
   {name:'/communityActivity',navItem:'社区动态'},
   {name:'/publishProject',navItem:'发布项目'},
   {name:'/personalCenter',navItem:'个人中心'},
   {name:'/manageCenter',navItem:'管理员中心'},
  ]
  }
 }

路由：


export default new Router({
 routes: [{
  path: '*',
  redirect: '/findProject'
 }, {
  path: '/findProject',
  name: 'findProject',
  component: findProject
 }, {
  path: '/communityActivity',
  name: 'communityActivity',
  component: communityActivity
 }, {
  path: '/publishProject',
  name: 'publishProject',
  component: publishProject
 }, {
  path: '/personalCenter',
  name: 'personalCenter',
  component: personalCenter
 }, {
  path: '/manageCenter',
  name: 'manageCenter',
  component: manageCenter
 }]
})

使用菜单栏进行路由跳转有几个注意点：

1. 在el-menu加上router

2. index必须绑定路由的path,参考上面的例子，'/'不能少

3. default-active设为当前路由（this.$router.path）,这样在路由变化的时候，对应的menu-item才会高亮。

拓展知识：vue项目中的路由配置方法

公司的项目使用vue脚手架来搭建，是属于后台管理系统。功能页比较多，就使用vue路由来进行跳转；

个人比较习惯上面这种方式放置路由文件，并且使用懒加载的模式来配置，如下：


import Vue from 'vue'
import Router from 'vue-router'
//import Login from '.././views/login.vue'
//import NotFound from '.././views/404.vue'
//import Home from '.././views/index.vue'
Vue.use(Router)
export default new Router({
 mode: 'history',//去掉#号
 routes: [
 {
  path: '/login',
  name: 'Login',
  component: resolve => require(['../views/login.vue'],resolve)
 },
 {
  path: '/404',
  name: 'NotFound',
  component: resolve => require(['../views/404.vue'],resolve)
 },
 {
  path: '/',
  redirect: '/default'
 },
 {
  path: '/',
  name: 'Home',
  component: resolve => require(['../views/index.vue'],resolve),
  meta: {title: '自述文件'},
  children:[
  {
   path: '/default',
   component: resolve => require(['../components/default.vue'],resolve),
   meta: {title: '系统首页'}
  },
  {
   path: '/set',
   component: resolve => require(['../components/set.vue'],resolve),
   meta: {title: '设置'}
  },
  {
   path: '/user',
   component: resolve => require(['../components/user.vue'],resolve),
   meta: {title: '账户管理'}
  },
  {
   path: '/member',
   component: resolve => require(['../components/memberList/memberList.vue'],resolve),
   meta: {title: '会员列表'}
  },
  {
   path: '/baseCharts',
   component: resolve => require(['../components/charts/baseCharts.vue'],resolve),
   meta: {title: '会员分析'}
  }
  ]
 }
 ]
})
