一、修改sidebar组件

src—layout—components—sidebar—index.vue

把组件sidebar改成drawer

<template>
  <div :class="{ 'has-logo': showLogo }">
    <el-drawer
      title=""
      direction="ltr"
      size="16%"
      :visible.sync="drawer.opened"
      :with-header="false"
    >
      <el-menu
        style="border-right: none"
        :default-active="activeMenu"
        :background-color="variables.menuBg"
        :text-color="variables.menuText"
        :unique-opened="false"
        :active-text-color="variables.menuActiveText"
        :collapse-transition="false"
        mode="vertical"
      >
        <sidebar-item
          v-for="route in routes"
          :key="route.path"
          :item="route"
          :base-path="route.path"
        />
      </el-menu>
    </el-drawer>
  </div>
</template>
<script>
import { mapGetters } from 'vuex'
import Logo from './Logo'
import SidebarItem from './SidebarItem'
import variables from '@/styles/variables.scss'

export default {
  components: { SidebarItem, Logo },
  computed: {
    ...mapGetters([
      'sidebar',
      'drawer',
    ]),
    routes () {
      return this.$router.options.routes
    },
    activeMenu () {
      const route = this.$route
      const { meta, path } = route
      // if set path, the sidebar will highlight the path you set
      if (meta.activeMenu) {
        return meta.activeMenu
      }
      return path
    },
    showLogo () {
      return this.$store.state.settings.sidebarLogo
    },
    variables () {
      return variables
    },
    isCollapse () {
      return !this.drawer.opened
    }
  }
}
</script>
<style>
.el-drawer {
  height: 430px !important;
  background-color: rgb(48, 65, 86);
}
.el-drawer__wrapper {
  top: 7%;
}
</style>

二、修改store

store—modules—app.js

store—getters.js

三、修改sidebaritem页面

layout—components—sidebar—sidebaritem.vue

methods: {
    toggleDrawer () {
      this.$store.dispatch('app/toggleDrawer')
    },
}

四、修改navbar页面

layout—components—navbar.vue

<hamburger
      :is-active="drawer.opened"
      class="hamburger-container"
      @toggleClick="toggleSideBar"
/>




    toggleSideBar () {
      this.$store.dispatch('app/toggleDrawer')
    },

五、修改layout

sidebar改成drawer

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

<script>
import { Navbar, Sidebar, AppMain } from './components'
import ResizeMixin from './mixin/ResizeHandler'

export default {
  name: 'Layout',
  components: {
    Navbar,
    Sidebar,
    AppMain
  },
  mixins: [ResizeMixin],
  computed: {
    sidebar () {
      return this.$store.state.app.drawer
    },
    device () {
      return this.$store.state.app.device
    },
    fixedHeader () {
      return this.$store.state.settings.fixedHeader
    },
    classObj () {
      return {
        // hideSidebar: !this.sidebar.opened,
        // openSidebar: this.sidebar.opened,
        withoutAnimation: this.sidebar.withoutAnimation,
        mobile: this.device === 'mobile'
      }
    }
  },
  methods: {
    handleClickOutside () {
      // this.$store.dispatch('app/closeSideBar', { withoutAnimation: false })
      this.$store.dispatch('app/closeSideBar')
    }
  }
}
</script>
<style lang="scss" scoped>
@import '~@/styles/mixin.scss';
@import '~@/styles/variables.scss';

.app-wrapper {
  @include clearfix;
  position: relative;
  height: 100%;
  width: 100%;
  &.mobile.openSidebar {
    position: fixed;
    top: 0;
  }
}
.drawer-bg {
  background: #000;
  opacity: 0.3;
  width: 100%;
  top: 0;
  height: 100%;
  position: absolute;
  z-index: 999;
}
.fixed-header {
  position: fixed;
  top: 0;
  right: 0;
  z-index: 9;
  // width: 100%;
  transition: width 0.28s;
}
// .hideSidebar .fixed-header {
//   width: calc(100% - 54px);
// }
.mobile .fixed-header {
  width: 100%;
}
.nav {
  position: fixed;
  top: 0;
  right: 0;
  z-index: 9;
  width: 100%;
  transition: width 0.28s;
}
</style>
