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>
