先上代码，项目结构图和效果图在后面展示。

1.TagsView.vue

                {{tag.title}}
                  <span class="el-icon-close" @click.prevent.stop='closeSelectedTag(tag)'></span>
              </router-link>
          </scroll-pane>
       <ul class='contextmenu' v-show="visible" :style="{left:left+'px',top:top+'px'}">

2.ScrollPane.vue:是当tagView内容超出一行时候的滚动（将鼠标悬浮在那一行上，不出现滚动条，该行就可以滚动）

<template>
  <div class="scroll-container" ref="scrollContainer" @wheel.prevent="handleScroll">
    <div class="scroll-wrapper" ref="scrollWrapper" :style="{left: left + 'px'}">
      <slot></slot>
    </div>
  </div>
</template>

<script>
  const padding = 15 // tag's padding

  export default {
    name: 'scrollPane',
    data() {
      return {
        left: 0
      }
    },
    methods: {
      handleScroll(e) {
        const eventDelta = e.wheelDelta || -e.deltaY * 3//wheelDelta:-120;deltaY:-120
        const $container = this.$refs.scrollContainer//外面的container
        const $containerWidth = $container.offsetWidth//外面的container的宽度
        const $wrapper = this.$refs.scrollWrapper//里面
        const $wrapperWidth = $wrapper.offsetWidth//里面的宽度

        if (eventDelta > 0) {
          this.left = Math.min(0, this.left + eventDelta)//min() 方法可返回指定的数字中带有最低值的数字。
        } else {
          if ($containerWidth - padding < $wrapperWidth) {
            if (this.left < -($wrapperWidth - $containerWidth + padding)) {
              this.left = this.left
            } else {
              this.left = Math.max(this.left + eventDelta, $containerWidth - $wrapperWidth - padding)
            }
          } else {
            this.left = 0
          }
        }
      },
      moveToTarget($target) {
        const $container = this.$refs.scrollContainer
        const $containerWidth = $container.offsetWidth
        const $targetLeft = $target.offsetLeft
        const $targetWidth = $target.offsetWidth

        if ($targetLeft < -this.left) {
          // tag in the left
          this.left = -$targetLeft + padding
        } else if ($targetLeft + padding > -this.left && $targetLeft + $targetWidth < -this.left + $containerWidth - padding) {
          // tag in the current view
          // eslint-disable-line
        } else {
          // tag in the right
          this.left = -($targetLeft - ($containerWidth - $targetWidth) + padding)
        }
      }
    }
  }
</script>

<style rel="stylesheet/scss" lang="scss" scoped>
  .scroll-container {
    white-space: nowrap;
    position: relative;
    overflow: hidden;
    width: 100%;
    .scroll-wrapper {
      position: absolute;
    }
  }
</style>

3.Store/tagsView.js

const tagsView = {
  state: {
    visitedViews: [],
    cachedViews: []
  },
  mutations: {
    ADD_VISITED_VIEWS: (state, view) => {
      if (state.visitedViews.some(v => v.path === view.path)) return
      state.visitedViews.push(Object.assign({}, view, {
        title: view.meta.title || 'no-name'
      }))
      if (!view.meta.noCache) {
        state.cachedViews.push(view.name)
      }
    },
    DEL_VISITED_VIEWS: (state, view) => {
      for (const [i, v] of state.visitedViews.entries()) {
        if (v.path === view.path) {
          state.visitedViews.splice(i, 1)
          break
        }
      }
      for (const i of state.cachedViews) {
        if (i === view.name) {
          const index = state.cachedViews.indexOf(i)
          state.cachedViews.splice(index, 1)
          break
        }
      }
    },
    DEL_OTHERS_VIEWS: (state, view) => {
      for (const [i, v] of state.visitedViews.entries()) {
        if (v.path === view.path) {
          state.visitedViews = state.visitedViews.slice(i, i + 1)
          break
        }
      }
      for (const i of state.cachedViews) {
        if (i === view.name) {
          const index = state.cachedViews.indexOf(i)
          state.cachedViews = state.cachedViews.slice(index, i + 1)
          break
        }
      }
    },
    DEL_ALL_VIEWS: (state) => {
      state.visitedViews = []
      state.cachedViews = []
    }
  },
  actions: {
    addVisitedViews({ commit }, view) {
      commit('ADD_VISITED_VIEWS', view)
    },
    delVisitedViews({ commit, state }, view) {
      return new Promise((resolve) => {
        commit('DEL_VISITED_VIEWS', view)
        resolve([...state.visitedViews])
      })
    },
    delOthersViews({ commit, state }, view) {
      return new Promise((resolve) => {
        commit('DEL_OTHERS_VIEWS', view)
        resolve([...state.visitedViews])
      })
    },
    delAllViews({ commit, state }) {
      return new Promise((resolve) => {
        commit('DEL_ALL_VIEWS')
        resolve([...state.visitedViews])
      })
    }
  }
}

export default tagsView

4.将tagsView.js引入到store/index.js中

import Vue from 'vue'
import Vuex from 'vuex'
import user from './modules/user'
import app from './modules/app'
import permission from './modules/permission'
import tagsView from './modules/tagsView'

import getters from './getters'

Vue.use(Vuex)
const store= new Vuex.Store({
  modules:{
    user,
    app,
    permission,
    tagsView

  },
  getters

})

export default store

总体功能分析：

1.选择左侧菜单的时候，通过监听路由变化，将左侧菜单的选中项缓存到store中，并显示在tagsView中

2.有右侧菜单事件：textmenu

3.点击名字时候，跳转到相应页面

4.点击关闭时候，关闭当前选项卡

项目结构：

别忘了再路由上面加name属性，楼主因为这个调试了好久
