一、动态树功能
二、数据表格
三、右侧文章的分页查询功能

一、动态树功能

<template>
	<el-menu  router :default-active="$route.path" default-active="2" class="el-menu-vertical-demo" background-color="#334157" text-color="#fff"
	 active-text-color="#ffd04b" :collapse="collapsed">
		<!-- <el-menu default-active="2" :collapse="collapsed" collapse-transition router :default-active="$route.path" unique-opened class="el-menu-vertical-demo" background-color="#334157" text-color="#fff" active-text-color="#ffd04b"> -->
		<div class="logobox">
			<img class="logoimg" src="../assets/img/logo.png" alt="">
		</div>
		<el-submenu :key="'id_'+m.treeNodeId" :index="'id_'+m.treeNodeId" v-for="m in menus">
			<template slot="title">
				<i :class="m.icon"></i>
				<span>{{m.treeNodeName}}</span>
			</template>
			<el-menu-item :key="'id_'+m2.treeNodeId" :index="m2.url" v-for="m2 in m.children">
				<template slot="title">
					<i :class="m2.icon"></i>
					<span>{{m2.treeNodeName}}</span>
				</template>
			</el-menu-item>
		</el-submenu>
	</el-menu>
</template>
<script>
	export default {
		data() {
			return {
				collapsed: false,
				menus:[]
			}
		},
		created() {
			//v就是从vue总线Bus获取的变量值
			this.$root.Bus.$on('collapsed-side-click', (v) => {
				this.collapsed = v;
			});

			let url = this.axios.urls.SYSTEM_MENU_TREE;
			this.axios.post(url, this.ruleForm).then((response) => {
				console.log(response);
				this.menus=response.data.result;
			}).catch(function(error) {
				console.log(error);
			});
		}
	}
</script>
<style>
	.el-menu-vertical-demo:not(.el-menu--collapse) {
		width: 240px;
		min-height: 400px;
	}

	.el-menu-vertical-demo:not(.el-menu--collapse) {
		border: none;
		text-align: left;
	}

	.el-menu-item-group__title {
		padding: 0px;
	}

	.el-menu-bg {
		background-color: #1f2d3d !important;
	}

	.el-menu {
		border: none;
	}

	.logobox {
		height: 40px;
		line-height: 40px;
		color: #9d9d9d;
		font-size: 20px;
		text-align: center;
		padding: 20px 0px;
	}

	.logoimg {
		height: 40px;
	}
</style>

二、数据表格

写组件：Articles.vue

<template>
	<div>
		<!-- 列表 -->
		<el-table size="small" :data="listData" element-loading-text="拼命加载中" style="width: 100%;">
			<el-table-column align="center" type="selection" min-width="1">
			</el-table-column>
			<el-table-column sortable prop="id" label="文章ID" min-width="1">
			</el-table-column>
			<el-table-column sortable prop="title" label="文章标题" min-width="3">
			</el-table-column>
			<el-table-column sortable prop="body" label="文章内容" min-width="5">
			</el-table-column>
			<!-- <el-table-column align="center" label="操作" min-width="300">
				<template slot-scope="scope">
					<el-button size="mini" @click="handleEdit(scope.$index, scope.row)">编辑</el-button>
					<el-button size="mini" type="danger" @click="deleteUser(scope.$index, scope.row)">删除</el-button>
				</template>
			</el-table-column> -->
		</el-table>
	</div>
</template>

<script>
	export default {
		data() {
			return {
				listData: []
			};
	},
		created() {
			let url = this.axios.urls.SYSTEM_ARTICLE_LIST;
				this.axios.post(url, this.ruleForm).then((response) => {
					console.log(response);
					this.listData = response.data.result;
				}).catch(function(error) {
					console.log(error);
				});
		}
	}
</script>

<style>

</style>

写路由：index.js

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import AppMain from '@/components/AppMain'
import Articles from '@/views/sys/Articles'
import Login from '@/views/Login'
import Reg from '@/views/Reg'

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: '/sys/Articles',
				name: 'Articles',
				component: Articles
			}]
		}
	]
})

在LfetNav.vue中加==router :default-active="$route.path"==以及更改一下传的参数值

<template>
	<el-menu  router :default-active="$route.path" default-active="2" class="el-menu-vertical-demo" background-color="#334157" text-color="#fff"
	 active-text-color="#ffd04b" :collapse="collapsed">
		<!-- <el-menu default-active="2" :collapse="collapsed" collapse-transition router :default-active="$route.path" unique-opened class="el-menu-vertical-demo" background-color="#334157" text-color="#fff" active-text-color="#ffd04b"> -->
		<div class="logobox">
			<img class="logoimg" src="../assets/img/logo.png" alt="">
		</div>
		<el-submenu :key="'id_'+m.treeNodeId" :index="'id_'+m.treeNodeId" v-for="m in menus">
			<template slot="title">
				<i :class="m.icon"></i>
				<span>{{m.treeNodeName}}</span>
			</template>
			<el-menu-item :key="'id_'+m2.treeNodeId" :index="m2.url" v-for="m2 in m.children">
				<template slot="title">
					<i :class="m2.icon"></i>
					<span>{{m2.treeNodeName}}</span>
				</template>
			</el-menu-item>
		</el-submenu>
	</el-menu>
</template>
<script>
	export default {
		data() {
			return {
				collapsed: false,
				menus:[]
			}
		},
		created() {
			//v就是从vue总线Bus获取的变量值
			this.$root.Bus.$on('collapsed-side-click', (v) => {
				this.collapsed = v;
			});

			let url = this.axios.urls.SYSTEM_MENU_TREE;
			this.axios.post(url, this.ruleForm).then((response) => {
				console.log(response);
				this.menus=response.data.result;
			}).catch(function(error) {
				console.log(error);
			});
		}
	}
</script>
<style>
	.el-menu-vertical-demo:not(.el-menu--collapse) {
		width: 240px;
		min-height: 400px;
	}

	.el-menu-vertical-demo:not(.el-menu--collapse) {
		border: none;
		text-align: left;
	}

	.el-menu-item-group__title {
		padding: 0px;
	}

	.el-menu-bg {
		background-color: #1f2d3d !important;
	}

	.el-menu {
		border: none;
	}

	.logobox {
		height: 40px;
		line-height: 40px;
		color: #9d9d9d;
		font-size: 20px;
		text-align: center;
		padding: 20px 0px;
	}

	.logoimg {
		height: 40px;
	}
</style>

三、右侧文章的分页查询功能

<template>
	<div>
		<!-- 搜索筛选 -->
		<el-form :inline="true" :model="formInline" class="user-search">
			<el-form-item label="搜索：">
				<el-input size="small" v-model="formInline.title" placeholder="输入文章标题"></el-input>
			</el-form-item>
			<el-form-item>
				<el-button size="small" type="primary" icon="el-icon-search" @click="search">搜索</el-button>
				<!-- <el-button size="small" type="primary" icon="el-icon-plus" @click="handleEdit()">添加</el-button> -->
			</el-form-item>
		</el-form>
		<!-- 列表 -->
		<el-table size="small" :data="listData" element-loading-text="拼命加载中" style="width: 100%;">
			<el-table-column align="center" type="selection" min-width="1">
			</el-table-column>
			<el-table-column sortable prop="id" label="文章ID" min-width="1">
			</el-table-column>
			<el-table-column sortable prop="title" label="文章标题" min-width="3">
			</el-table-column>
			<el-table-column sortable prop="body" label="文章内容" min-width="5">
			</el-table-column>
			<!-- <el-table-column align="center" label="操作" min-width="300">
				<template slot-scope="scope">
					<el-button size="mini" @click="handleEdit(scope.$index, scope.row)">编辑</el-button>
					<el-button size="mini" type="danger" @click="deleteUser(scope.$index, scope.row)">删除</el-button>
				</template>
			</el-table-column> -->
		</el-table>
		<!-- 分页条 -->
		<el-pagination style="margin-top: 20px;" @size-change="handleSizeChange" @current-change="handleCurrentChange"
		 :current-page="formInline.page" :page-sizes="[10, 20, 30, 50]" :page-size="100" layout="total, sizes, prev, pager, next, jumper"
		 :total="total">
		</el-pagination>
	</div>
</template>

<script>
	export default {
		data() {
			return {
				listData: [],
				formInline: {
					page: 1,
					rows: 10
				},
				total: 0
			};
		},
		methods: {
			handleSizeChange(rows) {
				//页大小发生改变触发的事件
				console.log("当前页大小："+rows);
				this.formInline.page = 1;
				this.formInline.rows = rows;
				this.search();
			},
			handleCurrentChange(page) {
				//当前页页码发生改变触发的事件
				console.log("当前页页码："+page);
				this.formInline.page = page;
				this.search();
			},
			doSearch(params){
				let url = this.axios.urls.SYSTEM_ARTICLE_LIST;
				this.axios.post(url, params).then((response) => {
					console.log(response);
					this.listData = response.data.result;
					this.total=response.data.pageBean.total;
				}).catch(function(error) {
					console.log(error);
				});
			},
			search(){
				this.doSearch(this.formInline);
			}
		},
		created() {
			this.doSearch({});
		}
	}
