实现思路及细节
1、利用前面博客所讲的Vuex的知识;定义几个变量
Options:存放tab页对象的容器(主要是路由路径以及tab页的名字)
activeIndex:被激活的tab页路由路径
showName:tab页的标题
Role:用来区分是否是因为左侧菜单被点击造成的路由路径发生改变;
是:pass;不是:nopass
2、左侧导航菜单绑定点击事件
将被点击的菜单名称存放到Vuex中,供路由路径变化监听时,tab页标题显示;
标记一下role为pass,到时新增tab页的时候需要作为判断依据
3、右侧对tab页进行操作
Tab页的点击(切换到被点击的tab页完成路由跳转;标记一下role为nopass,到时新增tab页的时候需要作为判断依据;);
Tab页的移除(删除指定的tab页对象;如果删除的tab页对象处于选中状态,需要将选中状态的下标移到最后一个,因为原来选中的tab页已经删除了;标记一下role为nopass,到时新增tab页的时候需要作为判断依据;))
4、监听路由路径变化
点亮已经存在的tab页(Vuex中showName与option中的哪个tab页对象的name相同,那么就点亮哪一个)
新增tab页(首先路由路径的变化是因为左侧栏的点击,其次要option中不存在的tab页对象)
效果图
State.js
export default{ resturantName: ‘飞歌餐馆‘, jwt:‘‘, options: [],//存放tab页的容器 activeIndex: ‘‘,//激活的tab页路由路径 showName:‘show‘,//tab页的标题 role:""//用来区分是否是因为左侧菜单被点击造成的路由路径发生改变,是:pass;不是:nopass }
Mutations.js
export default { setResturantName: (state, payload) => { state.resturantName = payload.resturantName; }, setJwt: (state, payload) => { state.jwt = payload.jwt; }, // 添加tabs(data包含了路由路径跟tab页名字) add_tabs(state, data) { this.state.options.push(data); }, // 删除tabs (route是路由路径) delete_tabs(state, route) { let index = 0; for (let option of state.options) { if (option.route === route) { break; } index++; } this.state.options.splice(index, 1); //删除options里面下标为Index的一个数 }, // 设置当前激活的tab set_active_index(state, index) { this.state.activeIndex = index; }, //设置tab页显示标题 set_showName(state, name) { this.state.showName = name; }, set_role(state, role) { this.state.role = role; } }
Getters.js
export default{ getResturantName:(state)=>{ return state.resturantName; }, getJwt:(state)=>{ return state.jwt; }, getResturantName: (state) => { return state.resturantName; }, getJwt: (state) => { return state.jwt; }, getShowName:(state) => { return state.showName; }, getOptions:(state) => { return state.options; }, getRole:(state) =>{ return state.role; } }

子tab页
添加一个子tab页数据
comment.vue
<template> <div> <el-tabs :tab-position="tabPosition" style="height: 200px;"> <el-tab-pane label="游客评论">游客评论管理</el-tab-pane> <el-tab-pane label="普通会员评论">普通会员评论管理</el-tab-pane> <el-tab-pane label="VIP会员评论">VIP会员评论管理</el-tab-pane> <el-tab-pane label="SVIP会员评论">SVIP会员评论管理</el-tab-pane> </el-tabs> </div> </template> <script> export default { data() { return { tabPosition: ‘评论管理‘ }; } } </script> <style> </style>
index.js配置
import Vue from ‘vue‘ import Router from ‘vue-router‘ import HelloWorld from ‘@/components/HelloWorld‘ import Login from ‘@/views/Login‘ import Reg from ‘@/views/Reg‘ import AppMain from ‘@/components/AppMain‘ import LeftNav from ‘@/components/LeftNav‘ import TopNav from ‘@/components/TopNav‘ import Articles from ‘@/views/sys/Articles‘ import VuexPage1 from ‘@/views/sys/VuexPage1‘ import VuexPage2 from ‘@/views/sys/VuexPage2‘ import comment from ‘@/views/sys/comment‘ Vue.use(Router) export default new Router({ routes: [{ path: ‘/‘, name: ‘Login‘, component: Login }, { path: ‘/Login‘, name: ‘Login‘, component: Login }, { path: ‘/Reg‘, name: ‘Reg‘, component: Reg }, { path: ‘/AppMain‘, name: ‘AppMain‘, component: AppMain, children: [{ path: ‘/LeftNav‘, name: ‘LeftNav‘, component: LeftNav }, { path: ‘/TopNav‘, name: ‘TopNav‘, component: TopNav }, { path: ‘/sys/Articles‘, name: ‘Articles‘, component: Articles }, { path: ‘/sys/VuexPage1‘, name: ‘VuexPage1‘, component: VuexPage1 }, { path: ‘/sys/VuexPage2‘, name: ‘VuexPage2‘, component: VuexPage2 }, { path: ‘/sys/comment‘, name: ‘comment‘, component: comment } ] } ] })
