Layout 布局组件快速搭建

设置主题样式变量

1. 创建主题变量文件：src/assets/styles/theme.scss

2. 添加页面布局组件用到的变量：

   :root {--os-layout-aside-width: 224px; // 侧边栏宽度--os-layout-logo-height: 56px; // 头部高度--os-layout-header-height: 56px; // 头部高度--os-layout-header-menu-width: 300px; // 头部菜单宽度--os-layout-footer-height: 40px; // 底部高度--os-layout-tab-height: 40px; // 底部高度
   }
   

3. 设置全局滚动条样式：

   /* scroll bar */
   ::-webkit-scrollbar {width: 6px;height: 6px;
   }::-webkit-scrollbar-thumb {background-color: var(--el-border-color-darker);border-radius: 20px;
   }
   

4. 在统一管理和维护项目的样式文件src/assets/styles/index.scss中导入主题样式文件：

   @import "theme.scss";
   

注：统一管理和维护项目的样式文件src/assets/styles/index.scss需在mian.ts中导入，注意导入顺序。

封装公共布局组件

   export interface ThemeConfig {showThemeConfig: boolean,darkThemeEnabled: boolean,grayThemeEnabled: boolean,layoutMode: LayoutMode,themePrimaryColor: string,predefineColors: string[]
   }
   

2. 创建 src/stores/modules/theme/index.ts 仓库存储主题状态：

   import { defineStore } from 'pinia'
   import { reactive, watch } from 'vue'
   import { ThemeConfig } from './types'
   import { ElMessage } from 'element-plus'
   import { getDarkColor, getLightColor } from '@/utils/Color'// theme store
   export const useThemeStore = defineStore('theme',() => {const themeConfig = reactive<ThemeConfig>({showThemeConfig: false,darkThemeEnabled: false,grayThemeEnabled: false,layoutMode: 'classic',themePrimaryColor: '#409eff',predefineColors: ['#409eff']})// 切换显示状态的方法const toggleThemeConfig = () => {themeConfig.showThemeConfig = !themeConfig.showThemeConfig}// 黑暗主题切换watch(() => themeConfig.darkThemeEnabled, () => {const html = document.documentElement as HTMLElementif (themeConfig.darkThemeEnabled) {html.setAttribute('class', 'dark')} else {html.removeAttribute('class')}changeThemeColor(themeConfig.themePrimaryColor)})watch(() => themeConfig.grayThemeEnabled,() => {if (themeConfig.grayThemeEnabled) {document.documentElement.dataset.theme = 'gray'} else {document.documentElement.dataset.theme = ''}})// 添加预定义颜色function addPredefineColor(color:string) {console.log('color', color)const predefineColors = themeConfig.predefineColors// 查找元素的索引const index = predefineColors.indexOf(color)if (index !== -1) {// 使用 splice 方法删除该元素predefineColors.splice(index, 1)}if (themeConfig.predefineColors.length === 10) {themeConfig.predefineColors.pop() // 删除队列中的第一个元素}themeConfig.predefineColors.unshift(color)}// 修改主题颜色const changeThemeColor = (color:string ) => {if (!color) {color = '#409eff'ElMessage({ type: 'success', message: '主题颜色已重置' })}addPredefineColor(color)// 计算主题颜色变化document.documentElement.style.setProperty('--el-color-primary', color)document.documentElement.style.setProperty('--el-color-primary-dark-2',themeConfig.darkThemeEnabled ? `${getLightColor(color, 0.2)}` : `${getDarkColor(color, 0.3)}`)for (let i = 1; i <= 9; i++) {const primaryColor = themeConfig.darkThemeEnabled ? `${getDarkColor(color, i / 10)}` : `${getLightColor(color, i / 10)}`document.documentElement.style.setProperty(`--el-color-primary-light-${i}`, primaryColor)}}return {themeConfig,toggleThemeConfig,changeThemeColor}},{persist: true})
   

3. 创建 src/layouts/components/Theme/index.vue 主题组件并引入主题仓库：

   }.layout-box {position: relative;display: flex;flex-wrap: wrap;justify-content: space-between;padding: 15px 15px 0;.layout-item {position: relative;box-sizing: border-box;width: 100px;height: 70px;padding: 6px;cursor: pointer;border-radius: 5px;box-shadow: 0 0 5px 1px var(--el-border-color-dark);transition: all 0.2s;.layout-dark {background-color: var(--el-color-primary);border-radius: 3px;}.layout-light {background-color: var(--el-color-primary-light-5);border-radius: 3px;}.layout-content {background-color: var(--el-color-primary-light-8);border: 1px dashed var(--el-color-primary);border-radius: 3px;}.select-layout {position: absolute;right: 10px;bottom: 10px;fill: var(--el-color-primary);transition: all 0.2s;}&:hover {box-shadow: 0 0 5px 1px var(--el-text-color-secondary);}}.is-active {box-shadow: 0 0 0 2px var(--el-color-primary) !important;}.layout-classic {display: flex;justify-content: space-between;margin-bottom: 20px;.layout-dark {width: 20%;}.layout-container {display: flex;flex-direction: column;justify-content: space-between;width: 72%;.layout-light {height: 20%;}.layout-content {height: 67%;}}}.layout-transverse {display: flex;flex-direction: column;justify-content: space-between;margin-bottom: 15px;.layout-dark {height: 20%;}.layout-content {height: 67%;}}
   }
   </style>
   

经典布局

1. 创建经典页面布局组件：src/layouts/LayoutClassic/index.vue：

2. 导入布局组件：

   <script setup lang="ts">
   import Footer from '@/layouts/components/Footer/index.vue'; // 引入页脚组件
   import Menu from '@/layouts/components/Menu/index.vue'; // 引入菜单组件
   import Logo from '@/layouts/components/Logo/index.vue'; // 引入Logo组件
   import Main from '@/layouts/components/Main/index.vue'; // 引入主要内容组件
   import TabBar from '@/layouts/components/TabBar/index.vue'; // 引入标签栏组件
   import Breadcrumb from '@/layouts/components/Breadcrumb/index.vue'; // 引入面包屑导航组件import { useThemeStore } from '@/stores/modules/theme' // 引入主题仓库
   const { toggleThemeConfig } = useThemeStore()
   

3. 使用 ElementPlus 提供的 Container 布局容器快速搭建页面的基本结构：

4. 在组件中使用布局组件划分出页面结构：侧边菜单栏、顶部、Tab 标签栏、主体和底部：

   <el-container>：外层容器。 当子元素中包含 <el-header> 或 <el-footer> 时，全部子元素会垂直上下排列， 否则会水平左右排列。

   <el-header>：顶栏容器。

   <el-aside>：侧边栏容器。

   <el-main>：主要区域容器。

   <el-footer>：底栏容器。

   <template><div class="layout-container"><el-container><!-- 左侧边栏 --><el-aside><!-- Logo 组件 --><Logo class="os-logo"/><!-- 菜单组件 --><Menu class="menu-classic" /></el-aside><el-container><!-- 页面顶部区域 --><el-header><!-- 头部内容区域 --><div class="header-content"><!-- 折叠按钮 --><svg-icon class="fold-expand-button" name="Fold" /><!-- 面包屑导航 --><Breadcrumb /></div><!-- 头部菜单区域 --><div class="header-menu"><!-- 语言切换下拉菜单 --><el-dropdown :hide-on-click="false"><svg-icon name="Earth" /><template #dropdown><el-dropdown-menu><el-dropdown-item>简体中文</el-dropdown-item></el-dropdown-menu></template></el-dropdown><!-- 搜索按钮 --><svg-icon class="cursor-pointer" name="Search" /><!-- 主题配置按钮 --><el-tooltip content="主题配置" placement="bottom"><svg-icon class="cursor-pointer" name="Theme" @click="toggleThemeConfig" /></el-tooltip><!-- 锁屏按钮 --><el-tooltip content="锁屏" placement="bottom"><svg-icon class="cursor-pointer" name="Lock" /></el-tooltip><!-- 全屏按钮 --><el-tooltip content="全屏" placement="bottom"><svg-icon class="cursor-pointer" name="FullScreen" /></el-tooltip><!-- 用户信息下拉菜单 --><el-dropdown><div class="flex items-center gap-1"><el-tag type="primary">Admin</el-tag><el-avatar src="https://cube.elemecdn.com/0/88/03b0d39583f48206768a7534e55bcpng.png" /></div><template #dropdown><el-dropdown-menu><el-dropdown-item command="profile"><template #default><div class="flex items-center gap-1"><svg-icon name="User" /><span>个人中心</span></div></template></el-dropdown-item><el-dropdown-item command="logout"><template #default><div class="flex items-center gap-1"><svg-icon name="Logout" /><span>退出登录</span></div></template></el-dropdown-item></el-dropdown-menu></template></el-dropdown></div></el-header><!-- 标签栏 --><tab-bar class="tab-container" /><!-- 主内容区域 --><el-main><Main /></el-main><!-- 底部页脚 --><el-footer><Footer /></el-footer></el-container></el-container></div>
   </template>
   

5. 为组件添加样式：

   <style scoped lang="postcss">
   .layout-container {@apply w-screen h-screen;.el-aside {@apply h-full;@apply border-r border-solid overflow-hidden;border-color: var(--el-border-color-light);width: var(--os-layout-aside-width);.os-logo {@apply overflow-hidden pl-2;}.menu-classic {height: calc(100vh - var(--os-layout-logo-height));}}.el-container {@apply h-full w-full;.tab-container {height: var(--os-layout-tab-height);}.el-header {@apply flex items-center justify-between;@apply border-b border-solid overflow-hidden;border-color: var(--el-border-color-light);height: var(--os-layout-header-height);.header-content {@apply flex items-center gap-5;.fold-expand-button {@apply cursor-pointer;@apply size-6;}}.header-menu {@apply flex items-center justify-between gap-3;}}.el-main {@apply h-full p-3;background-color: var(--el-bg-color-page);}.el-footer {height: var(--os-layout-footer-height);}}
   }
   </style>

2. 添加公共组件：

   <script setup lang="ts">
   import Logo from '@/layouts/components/Logo/index.vue'
   import Main from '@/layouts/components/Main/index.vue'
   import Menu from '@/layouts/components/Menu/index.vue'
   import { ref } from 'vue'import { useThemeStore } from '@/stores/modules/theme'
   const { themeConfig } = useThemeStore()const navDrawer = ref(false)
   const menuDrawer = ref(false)
   const translateShow = ref(false)

搭建 Layout 布局组件

1. 创建 Layout 布局组件 src/layouts/index.vue

2. 导入经典布局组件 LayoutClassic 和水平布局组件 LayoutHorizontal，创建一个 layoutMode 对象来将布局模式字符串映射到相应的组件，使用 computed 函数根据 mode 动态选择布局模式。

   <script setup lang="ts">
   import { type Component, computed, onMounted, onUnmounted, ref, watch } from 'vue'
   import LayoutClassic from '@/layouts/LayoutClassic/index.vue'
   import LayoutHorizontal from '@/layouts/LayoutHorizontal/index.vue'
   import LayoutResponsive from '@/layouts/LayoutResponsive/index.vue'
   import Theme from '@/layouts/components/Theme/index.vue'import { useThemeStore } from '@/stores/modules/theme'
   const { themeConfig } = useThemeStore()// 定义布局模式与对应的组件类型
   const layoutMode: Record<string, Component> = {classic: LayoutClassic,   // 经典布局horizontal: LayoutHorizontal,  // 横向布局responsive: LayoutResponsive  // 响应式布局
   }// 布局模式
   const layMode = ref(themeConfig.layoutMode)// 监听主题配置模式
   watch(() => themeConfig.layoutMode, (newMode) => {layMode.value = newMode
   })// 计算属性，根据具体逻辑返回所选布局的组件
   const mode = computed(() => layoutMode[layMode.value])// 响应式布局，切换布局模式
   const updateMode = () => {if (window.innerWidth <= 768) {layMode.value = 'responsive'} else {layMode.value = themeConfig.layoutMode}
   }onMounted(() => {// 初始更新updateMode()window.addEventListener('resize', updateMode)
   })onUnmounted(() => {window.removeEventListener('resize', updateMode)
   })
   </script><template><!-- 根据 mode 的值渲染不同的布局样式 --><component :is="mode" /><Theme />
   </template><style scoped lang="postcss">
   </style>
   

添加 Layout 路由配置

1. 在 src/App.vue 中添加代码，当访问路由路径时，Vue Router 会根据路由配置将对应的组件渲染到 <router-view> 中，实现单页应用的页面切换效果：

   <template><router-view />
   </template>
   

2. 在 src/router/index.ts 中添加路由：

   const router = createRouter({routes: [{path: '/',name: 'layout',component: () => import('@/layouts/index.vue')}]
   })
   

启动项目

1. 终端执行命令启动项目：

   pnpm run dev
   

2. 浏览器访问：http://localhost:8080/，默认为经典布局样式：

   

3. 在 src/layouts/index.vue 中切换为水平布局样式，查看页面：

   const mode = computed(() => layoutMode['horizontal'])
