导航左-菜单 交互后台

LeftNav.vue：

<template>
	<el-menu  router :default-active="$route.path" default-active="2" class="el-menu-vertical-demo" background-color="#334157" text-color="#fff"
		active-text-color="#ffd04b" :collapse="collapsed">

		<div class="logobox">
			<img class="logoimg" src="../assets/img/logo.png" alt="">
		</div>
		<el-submenu v-for="m in menus" :index="'idx'+m.id" :key="'key'+m.id">
			<template slot="title">
				<i class="m.icon"></i>
				<span>{{m.text}}</span>
			</template>
			<el-menu-item v-for="m2 in m.modules" :index="m2.url" :key="'key'+m2.id">

	</el-menu>
</template>
<script>
	// 从axios中导出数据☞
	export default {
		data() {
			return {
				// 展开
				collapsed: false,
				// 保存了左侧值
				menus: []
			}
		},
		created() {
			this.$root.bus.$on('shrink', t => {
				this.collapsed = t;
			});
 
			// 获取到左侧菜单的url
			let url = this.axios.urls.SYSTEM_MENUS;
			// 参数传递可以不传
			this.axios.get(url, {}).then(r => {
				this.menus = r.data.rows;
			}).catch(e => {
 
			});
		}
 
	}
</script>
<style>
	.el-menu-vertical-demo:not(.el-menu--collapse) {
		width: 240px;
		min-height: 400px;
	}
 
	.el-menu-vertical-demo:not(.el-menu--collapse) {

	}
 
	.logoimg {

</style>

通过动态路由跳转为当前项内容

router :default-active="$route.path"

定义组件的和路由的关系

index.js

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import AppMain from '@/components/AppMain'
import LeftNav from '@/components/LeftNav'
import TopNav from '@/components/TopNav'
import Login from '@/views/Login'
import Register from '@/views/Register'
 
import AddBook from '@/views/book/AddBook'
import BookList from '@/views/book/BookList'
 
 
Vue.use(Router)
 
export default new Router({
	routes: [{
			path: '/',
			name: 'Login',
			component: Login
		},
		{
			path: '/Register',
			name: 'Register',
			component: Register
		},
		{
			path: '/HelloWorld',
			name: 'HelloWorld',
			component: HelloWorld
		},
		{
			path: '/AppMain',
			name: 'AppMain',
			component: AppMain,
			children:[{
				path: '/TopNav',
				name: 'TopNav',
				component: TopNav
			}, {
				path: '/LeftNav',
				name: 'LeftNav',
				component: LeftNav
			},
			{
				path: '/book/AddBook',
				name: 'AddBook',
				component: AddBook
			}, {
				path: '/book/BookList',
				name: 'BookList',
				component: BookList
			}]
		}
 
	]
})

action.js

/**
 * 对后台请求的地址的封装，URL格式如下：
 * 模块名_实体名_操作
 */
export default {
	'SERVER': 'http://localhost:8080', //服务器
	'SYSTEM_USER_DOLOGIN': '/user/userLogin', //登陆
	'SYSTEM_USER_DOREG': '/user/Register', //注册
	'SYSTEM_MENUS': '/module/queryRootNode', //左侧菜单树
	'BOOK_LIST': '/book/queryBookPager', //书籍列表
	'getFullPath': k => { //获得请求的完整地址，用于mockjs测试时使用
		return this.SERVER + this[k];
	}
}

数据表格

BookList.vue

<template>
	<div class="books" style="padding: 20px;">
		<!-- 搜索框 -->
