vue-element-vue修改菜单切换标签，tagsview

1、从 vue-element-admin 项目中复制文件到对应的项目中文件夹中

• 将 vue-admin-template\src\layout\components\TagsView 文件夹
• vue-admin-template\src\store\modules\tagsView.js

2、修改vue-admin-template\src\layout\components\AppMain.vue ：AppMain.vue文件，新增以下内容

<template>
  <section class="app-main">
    <transition name="fade-transform" mode="out-in">
      <keep-alive :include="cachedViews">
          <router-view :key="key" />
      </keep-alive>
    </transition>
  </section>
</template>


<script>
export default {
  name: 'AppMain',
  computed: {
    //需要缓存的页面 固钉
    cachedViews() {
      return this.$store.state.tagsView.cachedViews
    },
    key() {
      return this.$route.fullPath
    }
  }
}
</script>


<style lang="scss" scoped>
.hasTagsView {
  .app-main {
    /* 84 = navbar + tags-view = 50 + 34 */
    min-height: calc(100vh - 84px);
  }

  .fixed-header+.app-main {
    padding-top: 84px;
  }
}
</style>

<style lang="scss">
// fix css style bug in open el-dialog
.el-popup-parent--hidden {
  .fixed-header {
    padding-right: 15px;
  }
}
</style>

3、修改vue-admin-template\src\layout\components\index.js，新增如下行

export { default as TagsView } from './TagsView'

4、在 vue-admin-template\src\layout\index.vue 文件中 新增 tagsview标签

<template>
  <div :class="classObj" class="app-wrapper">
    <div v-if="device==='mobile'&&sidebar.opened" class="drawer-bg" @click="handleClickOutside" />
    <sidebar class="sidebar-container" />
    <div class="main-container">
      <div :class="{'fixed-header':fixedHeader}">
        <navbar />
      </div>
      <tags-view />    <!-- 此处增加tag-->
      <app-main />
    </div>
  </div>
</template>

import { Navbar, Sidebar, AppMain, TagsView } from './components'

components: {
    Navbar,
    Sidebar,
    AppMain,
    TagsView
  },

5、vue-admin-template\src\store\getters.js，增加：

visitedViews: state => state.tagsView.visitedViews,
cachedViews: state => state.tagsView.cachedViews,

6、修改 vue-admin-template\src\store\index.js

import tagsView from './modules/tagsView'

const store = new Vuex.Store({
  modules: {
    app,
    permission,
    settings,
    tagsView, <!-- 此处新增-->
    user
  },
  getters
})

7、修改vue-admin-template\src\settings.js 添加

tagsView: true,

8、修改vue-admin-template\src\store\modules\settings.js

const { showSettings, tagsView, fixedHeader, sidebarLogo } = defaultSettings

const state = {
  showSettings: showSettings,
  tagsView: tagsView, <!-- 此处新增-->
  fixedHeader: fixedHeader,
  sidebarLogo: sidebarLogo
}

9、解决控制台报错

删除vue-admin-template\src\layout\components\TagsView\index.vue中routes方法
