Element-plus安裝及基礎(chǔ)組件使用詳解
簡而言之,在main.js中導(dǎo)出以下庫,僅此,搞多了出錯難排查
import ElementPlus from 'element-plus' //導(dǎo)入
ElementPlus模塊import 'element-plus/dist/index.css' //引入樣式
app.use(ElementPlus) //注冊庫就能使用了
Element Plus 是一個基于 Vue 3 的組件庫,提供了一系列 UI 組件(如按鈕、表格、對話框等),可以幫助快速構(gòu)建用戶界面。那么提供了該組件跟我平常直接在<template></template>標(biāo)簽中直接寫<button></button>標(biāo)簽來創(chuàng)建按鈕有什么區(qū)別?
Element Plus組件實際上是對原生 HTML 和 CSS 的封裝,它提供了一系列預(yù)定義的樣式和功能,使得開發(fā)者可以更輕松地構(gòu)建一致且美觀的用戶界面封裝:
Element Plus組件將原生 HTML 元素(如按鈕、表格等)進(jìn)行了封裝,增加了豐富的樣式和功能選項。樣式與一致性:組件自帶的樣式確保了在不同設(shè)備和瀏覽器上的一致性,減少了樣式調(diào)整的復(fù)雜性。
事件處理:盡管組件庫提供了許多內(nèi)置功能,事件處理仍然需要使用 JavaScript 進(jìn)行定義和處理。這與原生 HTML 是一樣的。
使用方便:通過使用組件,開發(fā)者可以更快地實現(xiàn)復(fù)雜的功能,而不必從頭開始設(shè)計和實現(xiàn)所有的樣式和行為。
一.安裝
使用包管理器:
# NPM
npm install element-plus --save
# Yarn
yarn add element-plus
# pnpm
pnpm install element-plus
如果網(wǎng)絡(luò)環(huán)境不好,建議使用中國npm鏡像:
設(shè)置清華大學(xué)鏡像并安裝element-plus:
npm config set registry https://mirrors.tuna.tsinghua.edu.cn/npm/
npm install element-plus中國科學(xué)技術(shù)大學(xué)(USTC)鏡像:
npm config set registry https://mirrors.ustc.edu.cn/npm/
npm install element-plus淘寶鏡像:
npm config set registry https://registry.npm.taobao.org
npm install element-plus使用cnpm 作為npm 的替代工具,自動使用淘寶鏡像
npm install -g cnpm --registry=https://registry.npm.taobao.org
cnpm install element-plus如果想要切換回npm官方源
npm config set registry https://registry.npmjs.org
瀏覽器直接引入:
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.在項目中使用Element Plus
引入:
(volar適用于ts,而對于js,使用vetur)
完整引入(對打包后的文件大小不在乎,使用完整導(dǎo)入更方便)
// main.js
import { createApp } from 'vue'
import ElementPlus from 'element-plus' //從element-plus庫中導(dǎo)入ElementPlus對象,該對象主要是庫的主要功能或組件集合,可在vue應(yīng)用中使用
import 'element-plus/dist/index.css' //引入樣式
import App from './App.vue'
const app = createApp(App)
app.use(ElementPlus) //注冊庫,所有Element Plus組件都可以在應(yīng)用中使用,在所有組件中都能使用
app.mount('#app')按需導(dǎo)入:
安裝額外插件來導(dǎo)入要使用的組件
安裝 unplugin-vue-components 和 unplugin-auto-import
npm install -D unplugin-vue-components unplugin-auto-import
將下面代碼插入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,千萬不要把它忘記了,報一堆錯,瀏覽器一片紅
AutoImport({
resolvers: [ElementPlusResolver()],
}),
Components({
resolvers: [ElementPlusResolver()],
}),
],
})作用:
自動導(dǎo)入:使用
unplugin-auto-import,可以在代碼中直接使用 Element Plus 的 API,而無需手動導(dǎo)入,這樣可以簡化代碼并提高開發(fā)效率。自動注冊組件:通過
unplugin-vue-components和ElementPlusResolver,可以自動注冊所有使用的 Element Plus 組件,避免在每個文件中重復(fù)注冊,簡化組件管理。提升開發(fā)體驗:減少樣板代碼,提高代碼整潔性和可維護(hù)性,使開發(fā)者能更專注于業(yè)務(wù)邏輯。
常見組件
Element Plus 的 API 包括組件、屬性、事件和方法等。以下是一些常見的 Element Plus API:
1.基礎(chǔ)組件:
- Button:按鈕組件,支持多種樣式和尺寸。
- Input:輸入框組件,支持文本輸入和驗證。
- Select:下拉選擇框組件,支持多選和搜索。
2.布局組件:
- Container:用于布局的容器組件,可以設(shè)置頂部、底部、側(cè)邊欄等。
- Row/Col:柵格布局組件,用于快速創(chuàng)建響應(yīng)式布局。
3.表單組件:
- Form:表單組件,支持表單驗證。
- Checkbox、Radio、Switch:用于選擇的各種組件。
4.反饋組件:
- Message:全局消息提示組件。
- Notification:通知提示組件。
5.數(shù)據(jù)展示組件:
- Table:表格組件,支持排序、篩選和分頁。
- Pagination:分頁組件,用于數(shù)據(jù)分頁展示。
組件的屬性和方法:屬性:每個組件都有一系列可配置的屬性,例如:
type、size:用于設(shè)置按鈕的類型和尺寸。placeholder:用于設(shè)置輸入框的占位符文本。
事件:組件通常會提供事件監(jiān)聽,例如:
click:按鈕的點擊事件。change:輸入框內(nèi)容變化時觸發(fā)的事件。
方法:某些組件提供的方法,可以在實例中調(diào)用,例如:
show():顯示模態(tài)框。hide():隱藏模態(tài)框。
全局配置
在引入ElementPlus時,可以傳入一個包含size和zIndex屬性的全局配置對象。size用于設(shè)置表單組建的默認(rèn)尺寸,zIndex用于設(shè)置彈出組件的層級,zIndex的默認(rèn)值為2000
完整引入(上邊注冊庫僅僅是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 })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>三.組件

rel="external nofollow"
target="_blank"
rel="noopener noreferrer"
>
a
</el-button>
</template>
13.自定義顏色(isDark: 這是一個響應(yīng)式變量,通常用于指示當(dāng)前主題是“深色模式(Dark Mode)”還是“淺色模式(Light Mode))
<script lang="ts" setup>
import { isDark } from '~/composables/dark'
</script>
<template>
<div>

<el-button color="#626aef" :dark="isDark" disabled plain>
Disabled Plain
</el-button>
</div>
</template>


button插槽:

button方法:


<el-button>:單個按鈕,用于執(zhí)行一個特定的操作。<el-button-group>:包含多個按鈕,通常用于一組相關(guān)的操作,比如多種選擇或工具欄。- 使用
button-group時,按鈕之間的間距和樣式會自動調(diào)整,視覺上更整齊
示例:
<template>
<el-button-group>
<el-button type="primary">按鈕1</el-button>
<el-button>按鈕2</el-button>
<el-button type="success">按鈕3</el-button>

color色彩:Element Plus為了避免視覺傳達(dá)差異,使用一套特定的調(diào)色板來規(guī)定顏色,為搭建的產(chǎn)品提供一致的外觀視覺感受
主色


中性色
中性色用于文本、背景和邊框顏色。 通過運用不同的中性色,來表現(xiàn)層次結(jié)構(gòu)



Container布局容器
用于布局的容器組件,方便快速搭建頁面的基本結(jié)構(gòu):
<el-container>:外層容器。 當(dāng)子元素中包含<el-header>或<el-footer>時,全部子元素會垂直上下排列, 否則會水平左右排列。
<el-header>:頂欄容器。
<el-aside>:側(cè)邊欄容器。
<el-main>:主要區(qū)域容器。
<el-footer>:底欄容器。
常見的頁面布局
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>
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>
3.container包裹aside和main,不過要指定側(cè)邊欄width屬性,明確指定側(cè)邊欄的寬度,從而確保整體布局的一致性和可預(yù)測性
用style設(shè)置容器背景色
height在<el-container>標(biāo)簽無效
<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>
4.三個部分,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>
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圖標(biāo)
Element Plus提供了一套常用的圖標(biāo)集合(如果想要直接使用,需要全局注冊組件)
安裝
使用包管理器
# NPM
npm install @element-plus/icons-vue# Yarn
yarn add @element-plus/icons-vue# pnpm
pnpm install @element-plus/icons-vue
法1:注冊所有圖標(biāo)需要從@element-plus/icons-vue 中導(dǎo)入所有圖標(biāo)并進(jìn)行全局注冊
Object.entries(ElementPlusIconsVue): 獲取ElementPlusIconsVue對象中所有的鍵值對(圖標(biāo)組件)。
for (const [key, component] of ...): 遍歷每個圖標(biāo)的鍵(名稱)和對應(yīng)的組件。
app.component(key, component): 將每個圖標(biāo)組件以其名稱注冊到 Vue 應(yīng)用中,使得在模板中可以直接使用這些圖標(biāo)。這樣,開發(fā)者就可以方便地在應(yīng)用中使用
ElementPlus提供的圖標(biāo)組件
// main.js
// 如果您正在使用CDN引入,請刪除下面一行。
import * as ElementPlusIconsVue from '@element-plus/icons-vue'
const app = createApp(App)
for (const [key, component] of Object.entries(ElementPlusIconsVue)) {
app.component(key, component)
}法2:直接通過瀏覽器的HTML標(biāo)簽導(dǎo)入Element Plus,然后就能使用全局變量ElementPlusIconsVue
根據(jù)不同的 CDN 提供商有不同的引入方式, 根據(jù)不同的 CDN 提供商有不同的引入方式, 我們在這里以 unpkg 和 jsDelivr 舉例
使用unpkg:
<script src="//unpkg.com/@element-plus/icons-vue"></script>
使用jsDelivr:
<script src="//cdn.jsdelivr.net/npm/@element-plus/icons-vue"></script>
基礎(chǔ)用法
<!-- 使用 el-icon 為 SVG 圖標(biāo)提供屬性 -->
<template>
<div>
<el-icon :size="size" :color="color">
<Edit />
</el-icon>
<!-- 或者獨立使用它,不從父級獲取屬性 -->
<Edit />
</div>
</template>
<!--<Edit /> 是一個 SVG 圖標(biāo)組件,通常來自 Element Plus 圖標(biāo)庫。它用于在界面中顯示一個編輯圖標(biāo)。代碼中的 <el-icon> 組件用來包裹這個圖標(biāo),并通過 :size 和 :color 屬性動態(tài)設(shè)置圖標(biāo)的大小和顏色。如果不使用 <el-icon> 包裹,<Edit /> 圖標(biāo)仍然可以獨立顯示,但會使用默認(rèn)樣式。-->結(jié)合el-icon使用
<template>
<p>
with extra class <b>is-loading</b>, your icon is able to rotate 360 deg in 2
seconds, you can also override this
</p>
<el-icon :size="20">
<Edit />
</el-icon>
<el-icon color="#409efc" class="no-inherit">
<Share />
</el-icon>
<el-icon>
<Delete />
</el-icon>
<el-icon class="is-loading">
<Loading />
</el-icon>
<el-button type="primary">
<el-icon style="vertical-align: middle">
<Search />
</el-icon>
<span style="vertical-align: middle"> Search </span>
</el-button>
</template>
直接使用svg圖標(biāo)
<template>
<div style="font-size: 20px">
<!-- 由于SVG圖標(biāo)默認(rèn)不攜帶任何屬性 -->
<!-- 你需要直接提供它們 -->
<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
通過基礎(chǔ)的24分欄,迅速簡便創(chuàng)建布局
組件默認(rèn)使用 Flex 布局,不需要手動設(shè)置 type="flex"。
請注意父容器避免使用 inline 相關(guān)樣式,會導(dǎo)致組件寬度不能撐滿。
1.el-row 行
el-col 列<el-col> 組件的 :span 屬性用于定義列的寬度
<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; /* 淺紫色 */
}
</style>
2.分欄間隔 gutter指定列之間的間距
<template>
<el-row :gutter="20">
<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-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>
3.混合布局

}
.el-col {
border-radius: 4px;
}
.grid-content {
border-radius: 4px;
min-height: 36px;
}
</style>
4.列偏移
