Vue3 + TS + Antd + Pinia 从零搭建后台系统(四) ant-design-vue Layout布局，导航栏，标签页

本文主要是介绍Vue3 + TS + Antd + Pinia 从零搭建后台系统(四) ant-design-vue Layout布局，导航栏，标签页，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

书接上回本篇主要介绍： Layout布局，导航栏，标签页继续填充

按需引入组件

使用unplugin-vue-components插件完成ant-design-vue组件的按需加载。
前文中已处理过，详情见前文

此处还需在tsconfig.json同级添加文件 components.d.ts。
tsconfig.json文件配置如下：

{"compilerOptions": {"target": "es2019","module": "esnext","strict": true,"jsx": "preserve","allowJs": true,"importHelpers": true,"moduleResolution": "node","outDir": "temp","resolveJsonModule": true,"experimentalDecorators": true,"esModuleInterop": true,"allowSyntheticDefaultImports": true,"sourceMap": true,"paths": {"@/*": ["src/*"]},"types": ["@intlify/unplugin-vue-i18n/types","vite/client","element-plus/global","@types/qrcode","vite-plugin-svg-icons/client","./components.d.ts"],"baseUrl": "./","lib": ["esnext", "dom", "dom.iterable", "scripthost"]},"include": ["src/types/**/*.ts","src/types/**/*.tsx","src/**/*.ts","src/**/*.tsx","src/**/*.vue","tests/**/*.ts","tests/**/*.tsx","src/components/BpmnEditor/lib/ReadOnly/ReadOnly.js","src/plugin/index.js"],"exclude": ["dist", "node_modules"]
}

Layout布局，导航栏，标签页

这里统一写在layout文件夹下面
此处用到的图标为iconfont图标库中的图标，可替换为ant-design-vue中的图标

index.vue文件：

<Layout style="height: 100%; width: 100%"><!-- 左侧菜单栏 --><Layout-sider:class="collapsed ? 'side-logo' : 'side-title'"v-model:collapsed="collapsed":trigger="null"collapsible><div style="height: 50px"><img class="logo-style" src="../../assets/images/logo.png" /><div v-if="!collapsed" class="title-style">管理平台</div></div><Menuv-model:selectedKeys="selectedKeys"v-model:openKeys="openKeys"theme="dark"mode="inline":inline-collapsed="collapsed"><Sub-menu v-for="sub in menuList" :key="sub.path"><template #title><span :class="sub.meta.icon" style="margin-right: 8px"></span><span>{{ !collapsed ? sub.meta.title : "" }}</span></template><Menu-item v-for="item in sub.children" :key="item.path"><span :class="item.meta.icon"></span><Router-link :to="`${sub.path}/${item.path}`">{{ item.meta.title }}</Router-link></Menu-item></Sub-menu></Menu></Layout-sider><!-- 右侧面包屑、标签页、界面 --><Layout><Layout-header style="height: 75px"><div class="layHeader"><div:class="`trigger icon-new ${!collapsed ?

index.ts文件：

import { defineComponent, reactive, toRefs, watch } from "vue";
import router from "@/router";
import { useUserStore } from "@/pinia/user";export default defineComponent({name: "Layout",setup() {const datas = reactive({selectedKeys: ["BBB"],openKeys: ["/AAA"],collapsed: false,menuList: [] as any,breadcrumbList: [],activeKey: "",tabPanes: [] as any,username: null as any,});const methods = reactive({init() {datas.username = JSON.parse(localStorage.getItem("user") as any).userInfo?.username;datas.menuList = router.options.routes.filter((v: any) => !v.meta.hideInMenu);datas.selectedKeys = [router.currentRoute.value.name];datas.openKeys = [router.currentRoute.value.matched[0].path];datas.breadcrumbList = router.currentRoute.value.matched;},onEdit(val: any) {let lastIndex = 0;if (datas.tabPanes.length > 1) {datas.tabPanes.forEach((item: any, i: number) => {if (item.path == val) {lastIndex = i - 1;}});datas.tabPanes = datas.tabPanes.filter((v: { path: any }) => v.path !== val);if (datas.tabPanes.length && datas.activeKey == val) {if (lastIndex >= 0) {datas.activeKey = datas.tabPanes[lastIndex].path;datas.selectedKeys = [datas.tabPanes[lastIndex].name];router.push(datas.tabPanes[lastIndex].path);} else {datas.activeKey = datas.tabPanes[0].path;datas.selectedKeys = [datas.tabPanes[0].name];}}}},onTabClick(val: any) {router.push(val);},loginOut() {// 使用Pinia中定义的退出系统的方法const userStore = useUserStore();userStore.logoutConfirm();},showAll() {// 此方法用来使用dropdown展示所有标签页的列表},closeOthers() {datas.tabPanes = datas.tabPanes.filter((v: { path: any }) => v.path == datas.activeKey);},reLoad() {window.location.reload();},});methods.init();watch(() => router.currentRoute.value.matched,(val) => {// 路由变化时，更新面包屑及标签页datas.breadcrumbList = val;datas.activeKey = router.currentRoute.value.path;if (datas.tabPanes.findIndex((v: any) => v.path == router.currentRoute.value.path) == -1) {datas.tabPanes.push(router.currentRoute.value);}},{ immediate: true });return {...toRefs(datas),...toRefs(methods),};},
});

css样式

style文件夹下，创建index.css 、antd.css、 layout.css

index.css

@import './antd.css';a {font-weight: 500;color: #646cff;text-decoration: inherit;
}
a:hover {color: #535bf2;
}body {margin: 0;display: flex;place-items: center;min-width: 320px;min-height: 100vh;
}h1 {font-size: 3.2em;line-height: 1.1;
}.card {padding: 2em;
}#app {margin: 0 auto;
}.main-content {margin: 10px;height: 100%;overflow-y: auto;
}

layout.css 样式

.side-logo {min-width: 60px !important;flex: 0 0 60px !important;
}
.side-title {flex: 0 0 180px !important;min-width: 180px !important;
}
.logo-style {float: left;margin: 4px;width: 40px;
}
.title-style {color: white;font-size: 18px;line-height: 48px;float: left;margin: 4px;font-weight: 700;
}
.trigger {width: 32px;font-size: 18px;line-height: 40px;padding: 0px;cursor: pointer;transition: color 0.3s;margin: 0 6px;
}.trigger:hover {color: #5487eae0 !important;
}
.content-style {margin: 8px;padding: 4px;background: #fff;min-height: 280px;
}
.loginOut {margin: 6px 0px 0;font-size: 15px;cursor: pointer;border-radius: 50% !important;padding: 0px 0px !important;width: 30px;
}
.loginOut:hover {color: #5487eae0 !important;
}
.fade-enter-active .fade-leave-active {transition: opacity 0.5s;
}
.layHeader {display: flex;height: 40px;border-bottom: 1px solid #05050530;
}
.spanIcon {width: 32px;height: 32px;border: 1px solid #05050530;padding: 8px 6px;opacity: 0.5;line-height: 14px;
}
.msg-style {background-color: #5487eae0;
}
.collased-menu-dropdown {transition: background 0.2s ease-in-out;
}

antd.css 调整组件库中的样式

.ant-btn {font-size: 14px !important;height: 28px !important;padding: 0px 10px !important;border-radius: 4px !important; margin: 2px 8px 2px 0px;
}
.ant-btn::before {margin: 4px;
}
.ant-btn:hover { opacity: 0.8;
}
.ant-form-inline .ant-form-item {margin: 0 8px 0 0 !important;
}
.ant-menu-dark .ant-menu-item-selected {border-radius: 4px !important; 
}
.ant-layout .ant-layout-header {padding-inline: 3px !important;background: #fff;
}
.ant-breadcrumb {padding: 8px 0 !important;font-size: 15px !important;width: calc(100% - 80px) !important;height: 50px;
}
.ant-tabs {width: calc(100% - 80px);
}
.ant-tabs-nav {height: 32px !important;margin-bottom: 8px !important;
}
.ant-tabs-nav .ant-tabs-nav-wrap {border-bottom: 1px solid #e6ebf3;
}
.ant-tabs-nav .ant-tabs-tab {border-top-right-radius: 4px !important;border-top-left-radius: 4px !important;padding: 8px 8px !important;
}
.ant-tabs .ant-tabs-tab-remove {margin: 2px -4px 0px 4px !important;
}
.ant-modal .ant-modal-header {margin-bottom: 20px;
}
