在了解了命名视图的用途后,发现用命名视图来实现复杂导航更加省力。更多知识请参考这里
这里只说明重要配置内容,其他内容配置请参考上一篇初始版本:
ElementUI 复杂顶部和左侧导航栏实现
或参考文末提到的github上的项目代码。
项目目录如下:
1、router配置(router/index.js)如下:
import Vue from 'vue' import Router from 'vue-router' import TopNav from '@/components/nav/topNav.vue' import LeftNav from '@/components/nav/leftNav.vue' import Home from '@/views/home.vue' import Dashboard from '@/views/workbench/dashboard.vue' import MySettings from '@/views/workbench/mySettings.vue' import Mission from '@/views/workbench/mission/mission.vue' import Plan from '@/views/workbench/plan.vue' import Maillist from '@/views/workbench/maillist.vue' import EnterpriseList from '@/views/enterprise/index.vue' import EnterpriseAdd from '@/views/enterprise/add.vue' import EnterpriseDetail from '@/views/enterprise/detail.vue' import EnterpriseValidate from '@/views/enterprise/validate.vue' import VehicleManage from '@/views/vehicle/index.vue' import DeptManager from '@/views/dept/index.vue' Vue.use(Router) let router = new Router({ routes: [ { path: '/', type: 'home', // 根据type区分不同模块(顶部导航) name: 'home', // 根据name区分不同子模块(左侧导航) redirect: '/dashboard', component: Home, children: [ { path: '/dashboard', name: '首页', // 当前路由的name(导航栏显示文字) components: { default: Dashboard, top: TopNav, aside: LeftNav }, leaf: true, // 只有一个节点 iconCls: 'iconfont icon-home', // 图标样式class menuShow: true }, { path: '/mySet', components: { default: MySettings, top: TopNav, aside: LeftNav }, name: '我的设置', iconCls: 'el-icon-menu', menuShow: true, children: [ { path: '/mySet/plan', component: Plan, name: '行程计划', menuShow: true }, { path: '/mySet/mission', component: Mission, name: '我的任务', menuShow: true }, { path: '/mySet/maillist', component: Maillist, name: '通讯录', menuShow: true } ] } ] }, { path: '/enterpriseManager', type: 'enterprise', name: 'enterprise', component: Home, redirect: '/enterprise/list', menuShow: true, children: [ { path: '/enterprise/list', name: '企业信息', components: { default: EnterpriseList, top: TopNav, aside: LeftNav }, leaf: true, iconCls: 'el-icon-setting', menuShow: true }, { path: '/enterprise/detail', name: '企业详情', components: { default: EnterpriseDetail, top: TopNav, aside: LeftNav }, leaf: true, iconCls: 'el-icon-setting', menuShow: false }, { path: '/enterprise/add', name: '添加企业', components: { default: EnterpriseAdd, top: TopNav, aside: LeftNav }, leaf: true, iconCls: 'el-icon-menu', menuShow: true }, { path: '/enterprise/validate', name: '企业认证', components: { default: EnterpriseValidate, top: TopNav, aside: LeftNav }, leaf: true, iconCls: 'el-icon-menu', menuShow: true } ] }, { path: '/vehicleManager', type: 'enterprise', name: 'vehicle', component: Home, redirect: '/vehicle/list', menuShow: true, children: [ { path: '/vehicle/list', name: '车辆信息', components: { default: VehicleManage, top: TopNav, aside: LeftNav }, leaf: true, // 只有一个节点 iconCls: 'iconfont icon-home', // 图标样式class menuShow: true } ] }, { path: '/deptManager', type: 'enterprise', name: 'dept', component: Home, redirect: '/dept/list', menuShow: true, children: [ { path: '/dept/list', name: '部门信息', components: { default: DeptManager, top: TopNav, aside: LeftNav }, leaf: true, // 只有一个节点 iconCls: 'iconfont icon-home', // 图标样式class menuShow: true } ] } ] });
特别说明:
这里的路由对象router ,设置的是最多三级,一级路由主要对应的是顶部导航和其他无子页面的路由,二级和三级路由分别对应的是左侧导航的一级和二级菜单(比如三级路由对应的就是左侧导航的二级菜单),二级路由设置leaf属性,值为true表明该路由下没有子菜单(如果该路由下的某页面不显示在左侧导航,不算子菜单)。
2、home.vue,这里分别有name=top,aside,default三个视图,top代表顶部导航,aside代表左侧导航,剩下的default就是默认视图,代表右侧内容区
3、topNav.vue 是顶部导航菜单的代码
注意fetchNavData()这个方法,主要是根据当前跳转的路由,去找到这个路由对应的type(对应顶部导航栏的分类)和name(对应左侧导航栏的分类),然后保存type和name到$store中,这样在topNav.vue组件可以根据$store中的type显示相应的菜单,同样在leftNav.vue组件就可以取到这个name值并显示相应的左侧菜单栏了。另外,里面的top和aside是命名视图,分别对应顶部导航组件和左侧导航组件。
补充:topNavState和leftNavState这两个状态就是精髓所在,分别控制顶部和左侧导航展示对应模块菜单,这两个状态是在vuex配置文件store.js中设置的
import Vue from 'vue' import Vuex from 'vuex' Vue.use(Vuex) const state = { collapsed: false, // 左侧导航折叠状态 topNavState: 'home', leftNavState: 'dispatch' } export default new Vuex.Store({ state })
store.js文件在main.js中引入:
import store from './store.js' new Vue({ router, store, el: '#app', render: h => h(App) })
4、leftNav.vue 左侧导航栏(这里的左侧菜单栏最多有两级菜单)
5、如果左侧导航含有二级菜单,
比如“我的设置(/mySet)”中,含有三个子菜单:
路由配置如下:(具体文件路径及配置请看router/index.js)
{ path: '/mySet', components: { default: MySettings, top: TopNav, aside: LeftNav }, name: '我的设置', iconCls: 'el-icon-menu', menuShow: true, children: [ { path: '/mySet/plan', component: Plan, name: '行程计划', menuShow: true }, { path: '/mySet/mission', component: Mission, name: '我的任务', menuShow: true }, { path: '/mySet/maillist', component: Maillist, name: '通讯录', menuShow: true } ] }
此时,我们只需在父级菜单对应视图(MySettings)中添加一个router-view即可:
