动态生成NavMenu导航菜单(只支持2级菜单)
1 结构 ：
<el-menu key="" index=""> <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 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="$route.path">
注1：要实现路由跳转，先要在el-menu标签上添加router属性，然后只要在每个el-menu-item标签内
的index属性设置一下url即可实现点击el-menu-item实现路由跳转。
注2：导航当前项，在el-menu标签中绑定 :default-active="$route.path",注意是绑定属性，
不要忘了加“:”,当$route.path等于el-menu-item标签中的index属性值时则该item为当前项。
注3：后台t_tree_node表有几个节点的url为空，则会导致几个节点样式会一致
(动态树)leftNav.vue:
<template>
<el-menu router :default-active="$route.path" 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" >
</div>
<!-- 注意：index是必填的 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-->
<el-submenu :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>
