Element-plus安装及其底子组件利用
简而言之,在main.js中导出以下库,仅此,搞多了出错难排查
import ElementPlus from 'element-plus' //导入ElementPlus 模块
import 'element-plus/dist/index.css' //引入样式
app.use(ElementPlus) //注册库就能利用了
Element Plus 是一个基于 Vue 3 的组件库,提供了一系列 UI 组件(如按钮、表格、对话框等),可以资助快速构建用户界面。那么提供了该组件跟我寻常直接在<template></template>标签中直接写<button></button>标签来创建按钮有什么区别?
Element Plus 组件实际上是对原生 HTML 和 CSS 的封装,它提供了一系列预界说的样式和功能,使得开发者可以更轻松地构建一致且雅观的用户界面
封装
:Element Plus 组件将原生 HTML 元素(如按钮、表格等)举行了封装,增加了丰富的样式和功能选项。
样式与一致性
:组件自带的样式确保了在不同装备和欣赏器上的一致性,淘汰了样式调整的复杂性。
事件处理
:尽管组件库提供了许多内置功能,事件处理仍然必要利用 JavaScript 举行界说和处理。这与原生 HTML 是一样的。
利用方便
:通过利用组件,开发者可以更快地实现复杂的功能,而不必从头开始筹划和实现所有的样式和行为。
一.安装
利用包管理器:
# NPM
npm install element-plus --save
# Yarn
yarn add element-plus
# pnpm
pnpm install element-plus
如果网络环境不好,发起利用中国npm镜像:
设置清华大学镜像并安装element-plus:
npm config set registry https://mirrors.tuna.tsinghua.edu.cn/npm/
npm install element-plus
中国科学技术大学(USTC)镜像:
npm config set registry https://mirrors.ustc.edu.cn/npm/
npm install element-plus
淘宝镜像:
npm config set registry https://registry.npm.taobao.org
npm install element-plus
利用cnpm 作为npm 的更换工具,主动利用淘宝镜像
npm install -g cnpm --registry=https://registry.npm.taobao.org
cnpm install element-plus
如果想要切换回npm官方源
npm config set registry https://registry.npmjs.org
欣赏器直接引入:
unpkg:
<head>
<!-- Import style -->
<link rel="stylesheet" href="//unpkg.com/element-plus/dist/index.css" />
<!-- Import Vue 3 -->
<script src="//unpkg.com/vue@3"></script>
<!-- Import component library -->
<script src="//unpkg.com/element-plus"></script>
</head>
jsDelivr:
<head>
<!-- Import style -->
<link
rel="stylesheet"
href="//cdn.jsdelivr.net/npm/element-plus/dist/index.css"
/>
<!-- Import Vue 3 -->
<script src="//cdn.jsdelivr.net/npm/vue@3"></script>
<!-- Import component library -->
<script src="//cdn.jsdelivr.net/npm/element-plus"></script>
</head>
二.在项目中利用Element Plus
引入:
(volar适用于ts,而对于js,利用vetur)
完整引入(对打包后的文件大小不在乎,利用完整导入更方便)
// main.js
import { createApp } from 'vue'
import ElementPlus from 'element-plus' //从element-plus库中导入ElementPlus对象,该对象主要是库的主要功能或组件集合,可在vue应用中使用
import 'element-plus/dist/index.css' //引入样式
import App from './App.vue'
const app = createApp(App)
app.use(ElementPlus) //注册库,所有Element Plus组件都可以在应用中使用,在所有组件中都能使用
app.mount('#app')
复制代码
按需导入:
安装额外插件来导入要利用的组件
安装 unplugin-vue-components 和 unplugin-auto-import
npm install -D unplugin-vue-components unplugin-auto-import
将下面代码插入vite配置文件vite.config.js中
// vite.config.js
import { defineConfig } from 'vite'
import AutoImport from 'unplugin-auto-import/vite'
import Components from 'unplugin-vue-components/vite'
import { ElementPlusResolver } from 'unplugin-vue-components/resolvers'
export default defineConfig({
plugins: [
vue(), //添加vue插件,千万不要把它忘记了,报一堆错,浏览器一片红
AutoImport({
resolvers: [ElementPlusResolver()],
}),
Components({
resolvers: [ElementPlusResolver()],
}),
],
})
复制代码
作用:
主动导入
:利用 unplugin-auto-import,可以在代码中直接利用 Element Plus 的 API,而无需手动导入,这样可以简化代码并进步开发效率。
主动注册组件
:通过 unplugin-vue-components 和 ElementPlusResolver,可以主动注册所有利用的 Element Plus 组件,克制在每个文件中重复注册,简化组件管理。
提升开发体验
:淘汰样板代码,进步代码整齐性和可维护性,使开发者能更专注于业务逻辑。
Element Plus 的 API 包括组件、属性、事件和方法等。以下是一些常见的 Element Plus API:
常见组件
1.底子组件:
Button
:按钮组件,支持多种样式和尺寸。
Input
:输入框组件,支持文本输入和验证。
Select
:下拉选择框组件,支持多选和搜索。
2.布局组件:
Container
:用于布局的容器组件,可以设置顶部、底部、侧边栏等。
Row/Col
:栅格布局组件,用于快速创建响应式布局。
3.表单组件:
Form
:表单组件,支持表单验证。
Checkbox
、
Radio
、
Switch
:用于选择的各种组件。
4.反馈组件:
Message
:全局消息提示组件。
Notification
:通知提示组件。
5.数据展示组件:
Table
:表格组件,支持排序、筛选和分页。
Pagination
:分页组件,用于数据分页展示。
组件的属性和方法:
属性
:每个组件都有一系列可配置的属性,例如:
type、size:用于设置按钮的范例和尺寸。
placeholder:用于设置输入框的占位符文本。
事件
:组件通常会提供事件监听,例如:
click:按钮的点击事件。
change:输入框内容变化时触发的事件。
方法
:某些组件提供的方法,可以在实例中调用,例如:
show():显示模态框。
hide():隐藏模态框。
全局配置
在引入ElementPlus时,可以传入一个包含size和zIndex属性的全局配置对象。size用于设置表单组建的默认尺寸,zIndex用于设置弹出组件的层级,zIndex的默认值为2000
完整引入(上边注册库仅仅是app.use(ElementPlus))
import { createApp } from 'vue'
import ElementPlus from 'element-plus'
import App from './App.vue'
const app = createApp(App)
app.use(ElementPlus, { size: 'small', zIndex: 3000 })
复制代码
按需引入:
<template>
<el-config-provider :size="size" :z-index="zIndex">
<app />
</el-config-provider>
</template>
<script>
import { defineComponent } from 'vue'
import { ElConfigProvider } from 'element-plus'
export default defineComponent({
components: {
ElConfigProvider,
},
setup() {
return {
zIndex: 3000,
size: 'small',
}
},
})
</script>
复制代码
三.组件
底子组件:
button按钮:
button属性:
1.type用来指定按钮内的配景颜色,但是按钮内的笔墨颜色是白色

<el-button type="success">Success</el-button>
<el-button type="info">Info</el-button>
<el-button type="warning">Warning</el-button>
<el-button type="danger">Danger</el-button>
</div>
复制代码
2.plain属性确定是否为朴素按钮,设置了朴素按钮之后,仅显示边框颜色和透明配景色
<div class="mb-4">
<el-button plain>Plain</el-button>
<el-button type="primary" plain>Primary</el-button> <!--有颜色的边框和文本,背景没有颜色-->
<el-button type="success" plain>Success</el-button>

height: 18px;
animation: loading-rotate 2s linear infinite;
}
.el-button .custom-loading .circular .path {
animation: loading-dash 1.5s ease-in-out infinite;
stroke-dasharray: 90, 150;
stroke-dashoffset: 0;
stroke-width: 2;
stroke: var(--el-button-text-color);
stroke-linecap: round;
}
</style>
复制代码
11.调整尺寸 size ="small" size="large"
<template>
<div class="flex flex-wrap items-center mb-4">
<el-button size="large">Large</el-button>
<el-button>Default</el-button>
<el-button size="small">Small</el-button>
<el-button size="large" :icon="Search">Search</el-button>
<el-button :icon="Search">Search</el-button>
<el-button size="small" :icon="Search">Search</el-button>
</div>
<div class="flex flex-wrap items-center mb-4">
<el-button size="large" round>Large</el-button>
<el-button round>Default</el-button>
<el-button size="small" round>Small</el-button>
<el-button size="large" :icon="Search" round>Search</el-button>
<el-button :icon="Search" round>Search</el-button>
<el-button size="small" :icon="Search" round>Search</el-button>
</div>
<div class="flex flex-wrap items-center">
<el-button :icon="Search" size="large" circle />
<el-button :icon="Search" circle />
<el-button :icon="Search" size="small" circle />
</div>
</template>
<script setup lang="ts">
import { Search } from '@element-plus/icons-vue'
</script>
复制代码
12.自界说元素标签 tag="div"d
<template>
<el-button>button</el-button>
<el-button tag="div" role="button" tabindex="0">div</el-button>
<el-button
type="primary"
tag="a"
href="https://github.com/element-plus/element-plus"
target="_blank"
rel="noopener noreferrer"
>
a
</el-button>
</template>
复制代码
13.自界说颜色(
isDark
: 这是一个响应式变量,通常用于指示当前主题是“深色模式(Dark Mode)”还是“浅色模式(Light Mode))
<script lang="ts" setup>
import { isDark } from '~/composables/dark'
</script>
<template>
<div>
<el-button color="#626aef" :dark="isDark">Default</el-button>
<el-button color="#626aef" :dark="isDark" plain>Plain</el-button>
<el-button color="#626aef" :dark="isDark" disabled>Disabled</el-button>
<el-button color="#626aef" :dark="isDark" disabled plain>
Disabled Plain
</el-button>
</div>
</template>
复制代码
button插槽:
button方法:
<el-button>
:单个按钮,用于实行一个特定的操纵。
<el-button-group>
:包含多个按钮,通常用于一组相干的操纵,比如多种选择或工具栏。
利用 button-group 时,按钮之间的间距和样式会主动调整,视觉上更整齐
示例:
<template>
<el-button-group>
<el-button type="primary">按钮1</el-button>
<el-button>按钮2</el-button>
<el-button type="success">按钮3</el-button>
</el-button-group>
</template>
复制代码
三个按钮被包裹在 button-group 中,形成了一个同一的操纵地域。
Border边框:

color色彩:Element Plus为了克制视觉转达差异,利用一套特定的调色板来规定颜色,为搭建的产品提供一致的表面视觉感受
主色
中性色
中性色用于文本、配景和边框颜色。 通过运用不同的中性色,来表现层次结构
Container布局容器
用于布局的容器组件,方便快速搭建页面的基本结构:
<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分列, 否则会水平左右分列。
<el-header>:顶栏容器。
<el-aside>:侧边栏容器。
<el-main>:主要地域容器。
<el-footer>:底栏容器。
常见的页面布局
1.container包裹header和main
<template>
<div class="common-layout">
<el-container>
<el-header style="background-color:#D4D7DE;color:red">Header</el-header>
<el-main style="background:#409EFF;color:blask">Main</el-main>
</el-container>
</div>
</template>
复制代码
2.container包裹header和main和footer
<template>
<div class="common-layout">
<el-container>
<el-header>Header</el-header>
<el-main>Main</el-main>
<el-footer>Footer</el-footer>
</el-container>
</div>
</template>
复制代码
3.container包裹aside和main,不过要指定侧边栏width属性,明确指定侧边栏的宽度,从而确保整体布局的一致性和可预测性
用style设置容器配景色
height在<el-container>标签无效
<template>
<div class="common-layout">
<el-container>
<el-aside width="200px" style="background-color:pink">Aside</el-aside>
<el-main style="background-color:red">Main</el-main>
</el-container>
</div>
</template>
复制代码
4.三个部分,大container包裹header和小container,小container包裹aside和main
<template>
<div class="common-layout">
<el-container>
<el-header>Header</el-header>
<el-container>
<el-aside width="200px">Aside</el-aside>
<el-main>Main</el-main>
</el-container>
</el-container>
</div>
</template>
复制代码
5.大container包裹所有,中container包裹aside,main,footer,小container包裹main和footer
<template>
<div class="common-layout">
<el-container>
<el-header>Header</el-header>
<el-container>
<el-aside width="200px">Aside</el-aside>
<el-container>
<el-main>Main</el-main>
<el-footer>Footer</el-footer>
</el-container>
</el-container>
</el-container>
</div>
</template>

lcon图标
Element Plus提供了一套常用的图标集合(如果想要直接利用,必要全局注册组件)
安装
利用包管理器
# NPM
npm install @element-plus/icons-vue
# Yarn
yarn add @element-plus/icons-vue
# pnpm
pnpm install @element-plus/icons-vue
法1:注册所有图标
必要从@element-plus/icons-vue 中导入所有图标并举行全局注册
Object.entries(ElementPlusIconsVue)
: 获取 ElementPlusIconsVue 对象中所有的键值对(图标组件)。
for (const [key, component] of ...)
: 遍历每个图标的键(名称)和对应的组件。
app.component(key, component)
: 将每个图标组件以其名称注册到 Vue 应用中,使得在模板中可以直接利用这些图标。
这样,开发者就可以方便地在应用中利用 ElementPlus 提供的图标组件
// main.js
// 如果您正在使用CDN引入,请删除下面一行。
import * as ElementPlusIconsVue from '@element-plus/icons-vue'
const app = createApp(App)
for (const [key, component] of Object.entries(ElementPlusIconsVue)) {
app.component(key, component)
}
复制代码
法2:直接通过欣赏器的HTML标签导入Element Plus,然后就能利用全局变量ElementPlusIconsVue
根据不同的 CDN 提供商有不同的引入方式, 根据不同的 CDN 提供商有不同的引入方式, 我们在这里以 unpkg 和 jsDelivr 举例
利用unpkg:
<script src="//unpkg.com/@element-plus/icons-vue"></script>
利用jsDelivr:
<script src="//cdn.jsdelivr.net/npm/@element-plus/icons-vue"></script>
底子用法
<!-- 使用 el-icon 为 SVG 图标提供属性 -->
<template>
<div>
<el-icon :size="size" :color="color">
<Edit />
</el-icon>
<!-- 或者独立使用它,不从父级获取属性 -->
<Edit />
</div>
</template>
<!--<Edit /> 是一个 SVG 图标组件,通常来自 Element Plus 图标库。它用于在界面中显示一个编辑图标。代码中的 <el-icon> 组件用来包裹这个图标,并通过 :size 和 :color 属性动态设置图标的大小和颜色。如果不使用 <el-icon> 包裹,<Edit /> 图标仍然可以独立显示,但会使用默认样式。-->

直接利用svg图标
<template>
<div style="font-size: 20px">
<!-- 由于SVG图标默认不携带任何属性 -->
<!-- 你需要直接提供它们 -->
<Edit style="width: 1em; height: 1em; margin-right: 8px" />
<Share style="width: 1em; height: 1em; margin-right: 8px" />
<Delete style="width: 1em; height: 1em; margin-right: 8px" />
<Search style="width: 1em; height: 1em; margin-right: 8px" />
</div>
</template>

Layout布局
通过底子的24分栏,迅速简便创建布局
组件默认利用 Flex 布局,不必要手动设置 type="flex"。
请注意父容器克制利用 inline 相干样式,会导致组件宽度不能撑满。
1.el-row 行
el-col 列
<el-col> 组件的 :span 属性用于界说列的宽度
<template>
<el-row>
<el-col :span="24"><div class="grid-content ep-bg-purple-dark"></div></el-col>
</el-row>
<el-row>
<el-col :span="12"><div class="grid-content ep-bg-purple"></div></el-col>
<el-col :span="12"><div class="grid-content ep-bg-purple-light"></div></el-col>
</el-row>
<el-row>
<el-col :span="8"><div class="grid-content ep-bg-purple"></div></el-col>
<el-col :span="8"><div class="grid-content ep-bg-purple-light"></div></el-col>
<el-col :span="8"><div class="grid-content ep-bg-purple"></div></el-col>
</el-row>
<el-row>
<el-col :span="6"><div class="grid-content ep-bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content ep-bg-purple-light"></div></el-col>
<el-col :span="6"><div class="grid-content ep-bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content ep-bg-purple-light"></div></el-col>
</el-row>
<el-row>
<el-col :span="4"><div class="grid-content ep-bg-purple"></div></el-col>
<el-col :span="4"><div class="grid-content ep-bg-purple-light"></div></el-col>
<el-col :span="4"><div class="grid-content ep-bg-purple"></div></el-col>
<el-col :span="4"><div class="grid-content ep-bg-purple-light"></div></el-col>
<el-col :span="4"><div class="grid-content ep-bg-purple"></div></el-col>
<el-col :span="4"><div class="grid-content ep-bg-purple-light"></div></el-col>
</el-row>
</template>
<style lang="scss">
.grid-content {
height: 100px; /* 或其他高度 */
}
.ep-bg-purple-dark {
background-color: #6a0dad; /* 深紫色 */
}
.ep-bg-purple {
background-color: #8a2be2; /* 紫色 */
}
.ep-bg-purple-light {
background-color: #d8bfd8; /* 浅紫色 */
}
</style>

<el-col :span="6"><div class="grid-content ep-bg-purple" /></el-col>
<el-col :span="6"><div class="grid-content ep-bg-purple" /></el-col>
<el-col :span="6"><div class="grid-content ep-bg-purple" /></el-col>
</el-row>
</template>
<style>
.el-row {
margin-bottom: 20px;
}
.el-row:last-child {
margin-bottom: 0;
}
.el-col {
border-radius: 4px;
}
.grid-content {
border-radius: 4px;
min-height: 36px;
}
</style>
复制代码
3.混合布局

space间距
虽然我们拥有 Divider 组件,但许多时候我们必要不是一个被 Divider 组件 分割开的页面结构,因此我们会重复的利用许多的 Divider 组件,这在我们的开发效率上造成了肯定的困扰。
间距组件
就是为了办理这种困扰应运而生的
