elementui 自定义增加标签页 动态绑定路由

效果如下：

el-header，el-aside，el-main布局，el-main中

<el-main>
          <el-tabs v-model="editableTabsValue" type="card" @tab-remove="removeTab" @tab-click="tabClick">
            <el-tab-pane
                v-for="(item, index) in editableTabs"
                :key="item.name"
                :label="item.title"
                :name="item.name"
                :closable="item.closable"
                >
            </el-tab-pane>
          </el-tabs>
          <keep-alive>
            <router-view></router-view>
          </keep-alive>
        </el-main>

 router-view 用来跳转路由，调用data如下

data() {
    return {
      activeIndex: '1',
      isCollapse: false,
      styleimg: 'fa fa-outdent',
      menulist: [],
      editableTabsValue: 'home',//tab选中name
      editableTabs: [],//tab数据
    }
  }

点击左侧菜单新增tab，menunametab名称，url为name，新增判断是否存在已经有的tab，

data中 editableTabsValue，editableTabs，都是取vuex里面设置的，后面贴代码

created() {
    //验证是否登录
    this.verification()
    //树形菜单
    this.getMenu()
    //初始化tab
    this.editableTabs = this.$store.state.options
    //网址进入选中tab
    this.initeditableTabsValue()
  }

//新增tab
    addTab(menuName,url) {
      let tabs = this.editableTabs;
      var isExist =false
      tabs.forEach((tab, index) => {
        if (tab.name === url) {
          isExist =true
        }
      })
      if (isExist){
        this.$store.commit('set_active_index', url)
        this.editableTabsValue =this.$store.state.activeIndex
      }
      else{
        this.$store.commit('add_tabs', {
          title: menuName,
          name: url,
          closable:true,
        })
        this.$store.commit('set_active_index', url)
        this.editableTabsValue =this.$store.state.activeIndex
      }
    },

 删除tab，移除vuex数据

//删除tab
    removeTab(targetName) {
      this.$store.commit('delete_tabs', targetName)
      this.$store.commit('set_active_index', 'home')
    },

tab点击

//tab点击
    tabClick(targetName){
      console.log(targetName)
      this.$store.commit('set_active_index', targetName.name)
      this.$router.push({path:'/'+targetName.name})
    },

输入网址，进入选中tab

//初始化tab加载选择
    initeditableTabsValue(){
      let url = this.$route.fullPath.replace('/','')
      let tabs = this.editableTabs;
      let isExist =false
      tabs.forEach((tab, index) => {
        if (tab.name === url) {
          isExist =true
        }
      })
      if (isExist){
        this.$store.commit('set_active_index', url)
        this.editableTabsValue =this.$store.state.activeIndex
      }else{
        this.$store.commit('set_active_index', 'home')
        this.editableTabsValue =this.$store.state.activeIndex
      }
    },

具体代码如下：

1.调用Vuex，index.js,options为editableTabs数据，写死一条主页tab，根据自己需要，这里vuex

actions，mutations，getters，modules分开了

import Vue from 'vue'
import Vuex from 'vuex'
import actions from "@/store/actions";
import mutations from "@/store/mutations";
import getters from "@/store/getters";
import modules from "@/store/modules";

Vue.use(Vuex)

const state = sessionStorage.getItem('state') ? JSON.parse(sessionStorage.getItem('state')) : {
  token: "",
  options: [{
    title: '主页',
    name: 'home',
    closable:false
  }],
  activeIndex: 'home'
}

export default new Vuex.Store({
  state,
  mutations,
  actions,
  getters,
  modules
})

2.mutations.js

export default {
    //添加token
    mGetToken(state, payload) {
        this.state.token = payload
    },

    // 添加tabs
    add_tabs (state, data) {
        this.state.options.push(data);
    },

    // 删除tabs
    delete_tabs (state, route) {
        let index = 0;
        for (let option of state.options) {
            if (option.name === route) {
                break;
            }
            index++;
        }
        this.state.options.splice(index, 1);
    },

    // 设置当前激活的tab
    set_active_index (state, index) {
        this.state.activeIndex = index;
    }

}

3.vue页面
