Vue导航栏部分的动态渲染实例_百厌_前端开发者

根据公司项目的需求,使用的是element-ui的nav-menu组件实现动态渲染左侧导航条的功能,这里我只写到了四级菜单。

代码部分:

<el-menu class='el-menu-vertical-demo' :router='true' v-for='(item, index) in navMenu' :key='index'>
  <el-submenu v-if='item.childs' :index='item.name' :route = 'item.value' class='edit_wrapper' @mouseover.native="overShow" @mouseout.native="outHide">
  <template slot='title'>
   <i :class='item.icon'></i>
   <span slot='title'>{{item.alias}}</span>
   <i class='iconfont icon-shenpi edit' v-show='haha'></i>
  </template>
  <el-submenu v-if='item1.childs' v-for= '(item1, index) in item.childs' :key='item1.name' :index='item1.name' :route='item1.value'>
   <template slot='title'>
   <i :class='item1.icon'></i>
   <span slot='title'>{{item1.alias}}</span>
   </template>
   <el-submenu v-for= '(item2, index) in item1.childs' :key='item2.name' v-if='item2.childs' :index='item2.name' :route = 'item2.value'>
   <template slot='title'>
    <i :class='item2.icon'></i>
    <span slot='title'>{{item2.alias}}</span>
   </template>
   <el-submenu v-for= '(item3, index) in item2.childs' :key='item3.name' v-if='item3.childs' ::index='item3.name' :route = 'item3.value'>
    <template slot='title'>
    <i :class='item3.icon'></i>
    <span slot='title'>{{item3.alias}}</span>
    </template>
    <el-menu-item v-for= '(item4, index) in item3.childs' :key='item3.name' v-if='item4.childs == null' :index='item4.name' :route = 'item4.value'>
    <span>{{item4.alias}}</span>
    </el-menu-item>
   </el-submenu>
   <el-menu-item v-for= '(item3, index) in item2.childs' :key='item3.name' v-if='item3.childs == null' :index='item3.name' :route = 'item3.value'>
    <span>{{item3.alias}}</span>
   </el-menu-item>
   </el-submenu>
   <el-menu-item v-for= '(item2, index) in item1.childs' :key='item2.name' v-if='item2.childs == null' :index='item2.name' :route = 'item2.value'>
   <span>{{item2.alias}}</span>
   </el-menu-item>
  </el-submenu>
  <el-menu-item v-for= '(item1, index) in item.childs' :key='item1.name' v-if='item1.childs == null' :index='item1.name' :route = 'item1.value'>
   <span>{{item1.alias}}</span>
  </el-menu-item>
  </el-submenu>
  <el-menu-item v-if='item.childs == null' :index='item.name' :route = 'item.value'>
  <i :class='item.icon'></i>
  <span slot='title'>{{item.alias}}</span>
  </el-menu-item>
  </el-menu>

数据部分:

navMenu: [{
  name: 'serveList',
  icon: 'iconfont icon-shezhi',
  alias: '金融服务目录',
  value: '',
  childs: [
  {
  name: 'channelManage',
  icon: '',
  alias: '渠道管理',
  value: '',
  childs: [
  {
   name: 'channelManage_in',
   icon: '',
   alias: '渠道内部管理',
   value: '',
   childs: [
   {
   name: 'financial',
   icon: '',
   alias: '金融类',
   value: '/serveManage/financial',
   },
   {
   name: 'no_financial',
   icon: '',
   alias: '非金融类',
   value: '/serveManage/no_financial',
   },
   {
   name: 'query_class',
   icon: '',
   alias: '查询类',
   value: '/serveManage/query_class',
   },
   {
   name: 'square_class',
   icon: '',
   alias: '冲正类',
   value: '/serveManage/square_class',
   },
   ]
  },
  {
   name: 'process_services',
   icon: '',
   alias: '流程服务',
   value: '/serveManage/process_services'
  },
  {
   name: 'cooperation_services',
   icon: '',
   alias: '合作方服务',
   value: '/serveManage/cooperation_services'
  },
  ]
  },
  {
  name: 'saveManage',
  icon: '',
  alias: '风险管理',
  value: '/serveManage/saveManage'
  }, {
  name: 'manageDecision',
  icon: '',
  alias: '管理决策',
  value: '/serveManage/manageDecision'
  }, {
  name: 'businessSupport',
  icon: '',
  alias: '业务支持',
  value: '/serveManage/businessSupport'
  }, {
  name: 'technicalSupport',
  icon: '',
  alias: '技术支持',
  value: '/serveManage/technicalSupport'
  }
  ]
 }, {
  name: 'serveRelation',
  icon: 'iconfont icon-shezhi',
  alias: '服务血缘关系',
  value: '/serveManage/serveRelation'
 }]

注意:因为含有childs的目录是没有路由的,所以可以把它的value值设为空。

效果展示:

这样我们就可以在其他页面引入该组件就可以了。
