若依框架新增自定义主题风格

实现结果

实现步骤

默认主题的设置

文件位置:src/settings.js

export default {// .../** * 侧边栏主题 深色主题theme-dark,浅色主题theme-light,蓝色主题theme-blue,炫彩主题theme-shine */sideTheme: 'theme-blue',// ...}
布局设置

图标文件

文件位置:src/assets/images/blue.svg

复制同级的 light.svg 修改名称即可,将两个颜色替换为:#409eff

<g id="配置面板" width="48" height="40" stroke="none" stroke-width="1" fill="none" fill-rule="evenodd"><g id="setting-copy-2" width="48" height="40" transform="translate(-1190.000000, -136.000000)"><g id="Group-8" width="48" height="40" transform="translate(1167.000000, 0.000000)"><g id="Group-5-Copy-5" filter="url(#filter-1)" transform="translate(25.000000, 137.000000)"><mask id="mask-3" fill="#409eff"><use xlink:href="#path-2"></use></mask><g id="Rectangle-18"><use fill="black" fill-opacity="1" filter="url(#filter-4)" xlink:href="#path-2"></use><use fill="#F0F2F5" fill-rule="evenodd" xlink:href="#path-2"></use></g><rect id="Rectangle-11" fill="#409eff" mask="url(#mask-3)" x="0" y="0" width="48" height="10"></rect><rect id="Rectangle-18" fill="#FFFFFF" mask="url(#mask-3)" x="0" y="0" width="16" height="40"></rect></g></g></g></g>
布局组件

文件位置:src/layout/components/Settings/index.vue

template模板中添加控件如下

新增一个主题风格选项,主要注意的是handleTheme里面的传参(后面会用到)和img的src图片,例如实例中的blue.svg

<div class="setting-drawer-block-checbox-item" @click="handleTheme('theme-blue')"><img src="@/assets/images/blue.svg" alt="blue" /><div v-if="sideTheme === 'theme-blue'" class="setting-drawer-block-checbox-selectIcon" style="display: block;"><i aria-label="图标: check" class="anticon anticon-check"><svg viewBox="64 64 896 896" data-icon="check" width="1em" height="1em" :fill="theme" aria-hidden="true"focusable="false" class><pathd="M912 190h-69.9c-9.8 0-19.1 4.5-25.1 12.2L404.7 724.5 207 474a32 32 0 0 0-25.1-12.2H112c-6.7 0-10.4 7.7-6.3 12.9l273.9 347c12.8 16.2 37.4 16.2 50.3 0l488.4-618.9c4.1-5.1.4-12.8-6.3-12.8z" /></svg></i></div></div>
准备CSS变量

文件位置:src/assets/styles/variables.module.scss

// 默认菜单主题风格$base-menu-blue-color: rgba(0, 0, 0, 0.7);$base-menu-blue-background: #ffffff;$base-logo-blue-title-color: #ffffff;$base-menu-shine-color: #ffffff;$base-menu-shine-background: rgba(0, 0, 0, 0);$base-logo-shine-title-color: #ffffff;// ...// 顶部菜单主题风格$base-navbar-color: #999093;$base-navbar-icon-color: #5a5e66;$base-navbar-background: #ffffff;$base-navbar-blue-color: #ffffff;$base-navbar-blue-background: #409eff;$base-navbar-shine-color: #ffffff;$base-navbar-shine-background: rgba(0, 0, 0, 0);// ...:export {menuBlueColor: $base-menu-blue-color;menuBlueBackground: $base-menu-blue-background;logoBlueTitleColor: $base-logo-blue-title-color;menuShineColor: $base-menu-shine-color;menuShineBackground: $base-menu-shine-background;logoShineTitleColor: $base-logo-shine-title-color;navbarColor: $base-navbar-color;navbarIconColor: $base-navbar-icon-color;navbarBlueColor: $base-navbar-blue-color;navbarShineColor: $base-navbar-shine-color;navbarBackground: $base-navbar-background;navbarBlueBackground: $base-navbar-blue-background;navbarShineBackground: $base-navbar-shine-background;// ...}

同级文件:sidebar.scss

左侧menu菜单的背景色和悬停样式

//新增样式,大概在112行& .theme-blue .nest-menu .el-sub-menu > .el-sub-menu__title,& .theme-blue .el-sub-menu .el-menu-item {background-color: $base-menu-blue-background !important;&:hover {color: $base-navbar-blue-color;background-color: $base-navbar-blue-background !important;}}
对状态管理库中的主题名称进行匹配

JS核心内容如下,若没有需手动添加。

import variables from '@/assets/styles/variables.module.scss'import useSettingsStore from '@/store/modules/settings'const settingsStore = useSettingsStore();const sideTheme = computed(() => settingsStore.sideTheme);
logo图标组件

文件位置:src/layout/components/Sidebar/Logo.vue

主要修改几个动态的style

<template><div class="sidebar-logo-container" :class="{ 'collapse': collapse }":style="{ backgroundColor: sideTheme === 'theme-dark' " />'theme-blue' ? variables.navbarBlueBackground : variables.menuLightBackground }"><transition name="sidebarLogoFade"><router-link v-if="collapse" key="collapse" class="sidebar-logo-link" to="/"><img v-if="logo" :src="logo" class="sidebar-logo" /><h1 v-else class="sidebar-title":style="{ color: sideTheme === 'theme-dark' ? variables.logoTitleColor : sideTheme === 'theme-blue' ? variables.logoBlueTitleColor : variables.logoLightTitleColor }">{{ title }}</h1></router-link><router-link v-else key="expand" class="sidebar-logo-link" to="/"><img v-if="logo" :src="logo" class="sidebar-logo" /><h1 class="sidebar-title":style="{ color: sideTheme === 'theme-dark' ? variables.logoTitleColor : sideTheme === 'theme-blue' ? variables.logoBlueTitleColor : variables.logoLightTitleColor }">{{ title }}</h1></router-link></transition></div></template>
左侧导航栏菜单组件

文件位置:src/layout/components/Sidebar/index.vue

<template><div :class="{ 'has-logo': showLogo }":style="{ backgroundColor: sideTheme === 'theme-dark' ? variables.menuBackground : sideTheme === 'theme-blue' ? variables.menuBlueBackground : variables.menuLightBackground }"><logo v-if="showLogo" :collapse="isCollapse" /><el-scrollbar :class="sideTheme" wrap-class="scrollbar-wrapper"><el-menu :default-active="activeMenu" :collapse="isCollapse":background-color="sideTheme === 'theme-dark' ? variables.menuBackground : sideTheme === 'theme-blue' ? variables.menuBlueBackground : variables.menuLightBackground":text-color="sideTheme === 'theme-dark' ? variables.menuColor : sideTheme === 'theme-blue' ? variables.menuBlueColor : variables.menuLightColor":unique-opened="true" :active-text-color="theme" :collapse-transition="false" mode="vertical"><sidebar-item v-for="(route, index) in sidebarRouters" :key="route.path + index" :item="route":base-path="route.path" /></el-menu></el-scrollbar></div></template>

样式文件专门对该组件进行了修改:src/assets/styles/sidebar.scss,若对侧边栏进行修改实现不了时,可查看是否是这里的问题,里面用了好多!important定义样式。

顶部导航栏组件

文件位置:src/layout/components/Navbar.vue

添加了一个动态style,

头像右边的el-icon组件,添加了color属性

<template><div class="navbar":style="{ backgroundColor: sideTheme === 'theme-dark' || sideTheme === 'theme-light' ? variables.navbarBackground : variables.navbarBlueBackground }"><div class="avatar-container"><el-dropdown @command="handleCommand" class="right-menu-item hover-effect" trigger="click"><div class="avatar-wrapper"><img :src="userStore.avatar" class="user-avatar" /><el-icon:color="sideTheme === 'theme-dark' || sideTheme === 'theme-light' ? variables.navbarIconColor : variables.navbarBlueColor"><caret-bottom /></el-icon></div></el-dropdown></div></div></template>

该文件下没有使用过主题名称匹配,需手动引入

该组件还引用了一些子组件,都需要对主题名称进行匹配


针对组件中使用到的svg-icon图标组件,修改如下:

组件都在src/components目录下,以文档地址图标为例,其他类似。

<template><div><svg-icon icon-class="question" @click="goto":color="sideTheme === 'theme-dark' || sideTheme === 'theme-light' ? variables.navbarIconColor : variables.navbarBlueColor" /></div></template><script setup>import variables from '@/assets/styles/variables.module.scss'import useSettingsStore from '@/store/modules/settings'const settingsStore = useSettingsStore();const sideTheme = computed(() => settingsStore.sideTheme);// ...</script>

控制左侧菜单栏收起展开的icon图标

文件位置:src/components/Hamburger/index.vue

给 svg 图标添加 fill 属性。

<template><div style="padding: 0 15px;" @click="toggleClick"><svg:class="{'is-active':isActive}":fill="sideTheme === 'theme-dark' || sideTheme === 'theme-light' ? variables.navbarIconColor : variables.navbarBlueColor"class="hamburger"viewBox="0 0 1024 1024"xmlns="http://www.w3.org/2000/svg"width="64"height="64"><path d="M408 442h480c4.4 0 8-3.6 8-8v-56c0-4.4-3.6-8-8-8H408c-4.4 0-8 3.6-8 8v56c0 4.4 3.6 8 8 8zm-8 204c0 4.4 3.6 8 8 8h480c4.4 0 8-3.6 8-8v-56c0-4.4-3.6-8-8-8H408c-4.4 0-8 3.6-8 8v56zm504-486H120c-4.4 0-8 3.6-8 8v56c0 4.4 3.6 8 8 8h784c4.4 0 8-3.6 8-8v-56c0-4.4-3.6-8-8-8zm0 632H120c-4.4 0-8 3.6-8 8v56c0 4.4 3.6 8 8 8h784c4.4 0 8-3.6 8-8v-56c0-4.4-3.6-8-8-8zM142.4 642.1L298.7 519a8.84 8.84 0 0 0 0-13.9L142.4 381.9c-5.8-4.6-14.4-.5-14.4 6.9v246.3a8.9 8.9 0 0 0 14.4 7z" /></svg></div></template><script setup>import variables from '@/assets/styles/variables.module.scss'import useSettingsStore from '@/store/modules/settings'const settingsStore = useSettingsStore();const sideTheme = computed(() => settingsStore.sideTheme);// ...</script>

最后,是对面包屑导航的处理

对span标签 a标签,添加动态style

<template><el-breadcrumb class="app-breadcrumb" separator="/"><transition-group name="breadcrumb"><el-breadcrumb-item v-for="(item, index) in levelList" :key="item.path"><span:style="{ color: sideTheme === 'theme-dark' || sideTheme === 'theme-light' ? variables.navbarColor : variables.navbarBlueColor }"v-if="item.redirect === 'noRedirect' || index == levelList.length - 1" class="no-redirect">{{ item.meta.title }}</span><a :style="{ color: sideTheme === 'theme-dark' || sideTheme === 'theme-light' ? variables.navbarColor : variables.navbarBlueColor }"v-else @click.prevent="handleLink(item)">{{ item.meta.title }}</a></el-breadcrumb-item></transition-group></el-breadcrumb></template><script setup>import variables from '@/assets/styles/variables.module.scss'import useSettingsStore from '@/store/modules/settings'const settingsStore = useSettingsStore();const sideTheme = computed(() => settingsStore.sideTheme);// ...</script>

炫彩主题

炫彩主题与自定义主题方法类似。只是将他们的背景色去掉。

这里提供一种添加炫彩主题的思路

实现结果

实现步骤

布局设置

找一张图片,放入位置:src/assets/images/theme-bg.jpg

布局组件

文件位置:src/layout/components/Settings/index.vue

为了样式美观,给img标签添加了style属性,svg图标填充颜色设为白色:fill='#ffffff'

<div class="setting-drawer-block-checbox-item" @click="handleTheme('theme-shine')"><img src="@/assets/images/theme-bg.jpg" alt="shine" style="width: 48px; height: 40px;" /><div v-if="sideTheme === 'theme-shine'" class="setting-drawer-block-checbox-selectIcon" style="display: block;"><i aria-label="图标: check" class="anticon anticon-check"><svg viewBox="64 64 896 896" data-icon="check" width="1em" height="1em" fill="#ffffff" aria-hidden="true"focusable="false" class><pathd="M912 190h-69.9c-9.8 0-19.1 4.5-25.1 12.2L404.7 724.5 207 474a32 32 0 0 0-25.1-12.2H112c-6.7 0-10.4 7.7-6.3 12.9l273.9 347c12.8 16.2 37.4 16.2 50.3 0l488.4-618.9c4.1-5.1.4-12.8-6.3-12.8z" /></svg></i></div></div>

炫彩主题需要背景色透明,不能实现固定header

<div class="drawer-item"><span>固定 Header</span><span class="comp-style"><el-switch v-model="fixedHeader" class="drawer-switch" :disabled="sideTheme === 'theme-shine'" /></span></div>

核心代码:

页面加载时向body元素中插入一个img元素,切换主题时控制img元素的显示/隐藏。

handleTheme()是主题切换时触发的函数。

import exampleImg from '@/assets/images/theme-bg.jpg'// ...// 在body下插入一个img元素,作为炫彩主题的背景const body = document.querySelector('body');const img = document.createElement('img');img.setAttribute('src', exampleImg);img.style.minWidth = '100%';img.style.minHeight = '100%';img.style.position = 'fixed';img.style.left = '0';img.style.top = '0';img.style.zIndex = '-1';// 获取当前主题名称,若当不是炫彩主题,将其隐藏if (settingsStore.sideTheme !== 'theme-shine') {img.style.display = 'none';}body.appendChild(img);function handleTheme(val) {// 选中炫彩主题,并且背景图为隐藏状态if (val == 'theme-shine' && img.style.display == 'none') {img.style.display = 'inline-block';// 炫彩主题需要背景色透明,不能实现固定headerfixedHeader.value = false;} else {img.style.display = 'none';}settingsStore.changeSetting({ key: 'sideTheme', value: val })sideTheme.value = val;}// ...
其他

剩下的修改的地方与上面类似。

下面是炫彩主题特有的:

展示内容的路由出口

文件位置:src/layout/components/AppMain.vue

添加动态style属性

样式修改如下:主要是让.app-main控件看着更舒服

<template><section class="app-main" :style="{ opacity: sideTheme === 'theme-shine' " />"></section></template><script setup>import useSettingsStore from '@/store/modules/settings'const settingsStore = useSettingsStore();const sideTheme = computed(() => settingsStore.sideTheme);</script><style lang="scss" scoped>.app-main {border-radius: 5px;margin: 5px;background-color: rgba(255, 255, 255, 1);/* 50= navbar50*/// min-height: calc(100vh - 50px);// width: 100%;position: relative;overflow: hidden;}.fixed-header+.app-main {padding-top: 50px;}.hasTagsView {.app-main {/* 84 = navbar + tags-view = 50 + 34 */// min-height: calc(100vh - 84px);}.fixed-header+.app-main {padding-top: 84px;}}</style>
布局设置-开启topNav后,顶部展示的组件

组件位置:src/components/TopNav/index.vue

添加两个动态:background-color属性

(这里改的比较粗糙,用到的时候再详细修改)

<template><el-menu:background-color="sideTheme === 'theme-shine' ? ' variables.navbarShineBackground' : variables.navbarBackground":default-active="activeMenu" mode="horizontal" @select="handleSelect" :ellipsis="false"><el-sub-menu:background-color="sideTheme === 'theme-shine' ? ' variables.navbarShineBackground' : variables.navbarBackground":style="{ '--theme': theme }" index="more" v-if="topMenus.length > visibleNumber"><template #title>更多菜单</template></el-sub-menu></el-menu></template>
打开页面切换的TagesViews

文件位置:src/layout/components/TagsView/index.vue

添加动态style属性。

<template><div :style="{ background: sideTheme === 'theme-shine' ? variables.navbarShineBackground : variables.navbarBackground }"id="tags-view-container" class="tags-view-container"></div></template>

补充非显示页面的标签样式

// ...import variables from '@/assets/styles/variables.module.scss'const settingsStore = useSettingsStore();const sideTheme = computed(() => settingsStore.sideTheme);// ...function activeStyle(tag) {if (!isActive(tag)) return {'color': sideTheme.value === 'theme-shine' ? variables.navbarShineColor : '','background-color': sideTheme.value === 'theme-shine' ? variables.navbarShineBackground : ''};return {"background-color": theme.value,"border-color": theme.value};}

好了,圆满结束。
