vue elementUI使用tabs与导航栏联动

不使用tabs标签页时，点击导航菜单，router-view映射相应的组件即可显示页面。但我们想在点击导航栏时在tabs中映射相应的组件，这就需要使用tabs组件
在slider.vue中点击路由后，把当前选择的路由@select使用bus传出去

<el-menu class="sidebar-el-menu" :default-active="onRoutes" :collapse="collapse" background-color="#eeefef" text-color="#666" active-text-color="#20a0ff" unique-opened router @select="addTab">

 <!-- 一级菜单 -->
  <template v-for="item in slidebarData" >
  <el-submenu v-if="item.subs && item.subs.length" :index="item.index" :key="item.index">
   <template slot="title"><i :class="item.icon"></i><span>{{item.title}}</span></template>

   <!-- 二级菜单 -->
   <template v-for="itemChild in item.subs">
   <el-submenu v-if="itemChild.subs && itemChild.subs.length" :index="itemChild.index" :key="itemChild.index" class="erji">
    <template slot="title"><i :class="itemChild.icon"></i><span>{{itemChild.title}}</span></template>

    <!-- 三级菜单 -->
    <el-menu-item v-for="itemChild_Child in itemChild.subs" :index="itemChild_Child.index" :key="itemChild_Child.index">
    <i :class="itemChild_Child.icon"></i><span slot="title">{{itemChild_Child.title}}</span>
    </el-menu-item>
   </el-submenu>

   <el-menu-item v-else :index="itemChild.index" :key="itemChild.index"><i :class="itemChild.icon"></i><span slot="title">{{itemChild.title}}</span></el-menu-item>
   </template>
  </el-submenu>

  <el-menu-item v-else :index="item.index" :key="item.index"><i :class="item.icon"></i><span slot="title">{{item.title}}</span></el-menu-item>
  </template>

 </el-menu>

使用bus把路由信息传出

import bus from '../common/bus';
methods: {
 addTab(key,keyPath) {
 console.log(key,keyPath)
 bus.$emit('navPath',keyPath)
 }
},

在tabs.vue中接收

<template>
 <div id="tabs">
 <el-tabs type="card" v-model="tabsVal" @tab-remove="closeTab" @tab-click="tabclick">
  <el-tab-pane v-for="item in tabList" :key="item.name" :name="item.name" :label="item.title" :closable="item.closable" >
        <component :is="item.component"></component>
      </el-tab-pane>
 </el-tabs>
 </div>
</template>

<script>
 import searchFor from '../page/ContentManagement/Class/searchFor.vue';
 import bus from '../common/bus';
 export default {
 data() {
  return {
  inputVisible: false,
  navPath: '',
  tabsVal: "searchFor",
  tabList: [
   {
        title: '热门搜索',
        name: 'searchFor',
        disabled: true,
        closable: false,
        component: searchFor
      }
  ]
  }
 },
 methods: {
  closeTab(tag) {//关闭tabs
  var tabListName = []
  for(let i = 0; i < this.tabList.length; i++){
   tabListName[i] = this.tabList[i].name;
  }
  console.log(tabListName)
  this.tabList.splice(tabListName.indexOf(tag), 1);
  this.tabsVal = "searchFor";
  this.$router.push("searchFor");
  },
  tabclick(val) {
  console.log(val)
  this.$router.push(val.name);
  //点击tabs触发路由跳转，到相应路由
  }
 },
 mounted () {
     bus.$on('navPath',(name,val) =>{//处理传过来的值
      console.log(name)
       var titname;
       if(name[name.length -1] == 'searchFor'){
        titname = '热门搜索'
       }else if(name[name.length -1] == 'Courier1'){
        titname = '套课列表'
       }else if(name[name.length -1] == 'Courier2'){
        titname = '小节列表'
       }else if(name[name.length -1] == 'Courier3'){
        titname = '套课分享'
       }
       if (this.tabList.filter(f => f.name == name[name.length -1]) == 0) {
        var component = resolve => require([`../page/ContentManagement/${name[0]}/${name[name.length -1]}`], resolve)//合伙人管理
        this.tabList.push({
          title: titname,
          name: name[name.length -1],
          disabled: false,
          closable: true,
          component: component
        })
       }
       this.tabsVal = name[name.length -1]
     });
    }
 }
</script>

<style scoped>
 #tabs {
 position: fixed;
