动态生成NavMenu导航菜单(只支持2级菜单)
2.1 结构
<el-submenu>
<template slot="title">
<i class="el-icon-location"></i>
<span>导航一</span>
</template>
<template slot="title">分组一</template>
<el-menu-item route="">
2.2 vue+element的el-menu组件实现路由跳转及当前项的设置
<el-menu router :default-active="$route.path">
<el-menu-item index="/company/userManager">用户管理</el-menu-item>
注1：要实现路由跳转，先要在el-menu标签上添加router属性，然后只要在每个el-menu-item标签内
的index属性设置一下url即可实现点击el-menu-item实现路由跳转。
注2：导航当前项，在el-menu标签中绑定 :default-active="$route.path",注意是绑定属性，
不要忘了加“:”,当$route.path等于el-menu-item标签中的index属性值时则该item为当前项。
注3：后台t_tree_node表有几个节点的url为空，则会导致几个节点样式会一致
2.3 数据表格
<el-table :data="result" style="width: 100%;" :border="true" max-height="550">
<el-table-column prop="id" label="ID" min-width="10" align="center"></el-table-column>
<el-table-column prop="title" label="标题" min-width="20"></el-table-column>
<el-table-column prop="body" label="内容" min-width="70"></el-table-column>
</el-table>

表格
<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" border element-loading-text="拼命加载中" style="width: 100%;">
<el-table-column align="center" type="selection" min-width="1">
<!--min-width: 对应列的最小宽度，与 width 的区别是 width 是固定的，min-width 会把剩余宽度按比例分配给设置了 min-width 的列 -->
</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">

<!-- 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"

</div>
</template>
<script>
export default {

listData: [],
formInline: { //传入后台
page: 1,
rows: 10,
title:""
},
total: 0
};
},
methods: {
doSearch(params) { //变成活值
let url = this.axios.urls.SYSTEM_ARTICLE_LIST;
this.axios.post(url, params).then((response) => {
console.log(response);
this.listData = response.data.result;

this.formInline.page = 1;
this.formInline.rows = rows;
this.search();

this.search();
},
search(){
this.doSearch(this.formInline);

树形菜单数据
<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 :index="'id_'+m.treeNodeId" v-for="m in menus">
<template slot="title">
<i :class="m.icon"></i>
<span>{
{m.treeNodeName}}</span>
</template>
<!-- 注意：index是必填的属性 1、index可以看成ID,也就是说它是唯一的
2、它代表路由的跳转路径-->
<!-- m是当前节点，m.children是所有子节点 -->
<el-menu-item :key="'id_'+m2.treeNodeId" :index="m2.url" v-for="m2 in m.children">
<i :class="m2.icon"></i>
<span>{
{m2.treeNodeName}}</span>
</el-menu-item>
</el-submenu>
</el-menu>
</template>
左树形菜单加载
<script>
export default {
data(){
return{
collapsed:false,//默认不折叠
menus:[]
}
},
created(){//初始化数据
this.$root.Bus.$on('collapsed-side',(v)=>{//参数：用回调函数
this.collapsed=v
})
let url=this.axios.urls.SYSTEM_MENU_TREE
this.axios.post(url,{}).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;
