Element-plus安装及其基础组件使用

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) //注册库就能使用了

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),可以帮助快速构建用户界面。那么提供了该组件跟我平常直接在<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,它提供了一系列预定义的样式和功能,使得开发者可以更轻松地构建一致且美观的用户界面

  1. 封装Element Plus 组件将原生 HTML 元素(如按钮、表格等)进行了封装,增加了丰富的样式和功能选项。

  2. 样式与一致性:组件自带的样式确保了在不同设备和浏览器上的一致性,减少了样式调整的复杂性。

  3. 事件处理:尽管组件库提供了许多内置功能,事件处理仍然需要使用 JavaScript 进行定义和处理。这与原生 HTML 是一样的。

  4. 使用方便:通过使用组件,开发者可以更快地实现复杂的功能,而不必从头开始设计和实现所有的样式和行为。

 一.安装

使用包管理器:

# NPM

 npm install element-plus --save

# Yarn

 yarn add element-plus

# pnpm 

pnpm install element-plus


如果网络环境不好,建议使用中国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
 

使用cnpm 作为npm 的替代工具,自动使用淘宝镜像

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
 

浏览器直接引入:

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.在项目中使用Element Plus

引入:
(volar适用于ts,而对于js,使用vetur)

完整引入(对打包后的文件大小不在乎,使用完整导入更方便)

// 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')

按需导入:
安装额外插件来导入要使用的组件

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()],
    }),
  ],
})

作用:
 

 自动导入:使用 unplugin-auto-import,可以在代码中直接使用 Element Plus 的 API,而无需手动导入,这样可以简化代码并提高开发效率。

自动注册组件:通过 unplugin-vue-componentsElementPlusResolver,可以自动注册所有使用的 Element Plus 组件,避免在每个文件中重复注册,简化组件管理。

提升开发体验:减少样板代码,提高代码整洁性和可维护性,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.基础组件:
 

  • 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。
  • CheckboxRadioSwitch: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:

    • typesize:用于设置按钮的类型和尺寸。
    • 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 })

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.组件

基础组件:
button按钮:

button属性:

1.type用来指定按钮内的背景颜色,但是按钮内的文字颜色是白色

    <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>

12.自定义元素标签 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>



13.自定义颜色(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>



button插槽:


button方法:





 

  • <el-button>:单个按钮,用于执行一个特定的操作。
  • <el-button-group>:包含多个按钮,通常用于一组相关的操作,比如多种选择或工具栏。
  • 使用 button-group 时,按钮之间的间距和样式会自动调整,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>

三个按钮被包裹在 button-group 中,形成了一个统一的操作区域。

Border边框:

边框样式:(实线和虚线)

border-top:1px solid var(--el-border-color)

<script setup>
</script>

  <template>
  <table class="demo-border">

}
.demo-border .line .dashed {
  border-top: 2px dashed var(--el-border-color);
}
</style>







圆角样式:(el-border-radius)

<script setup>

}
</script>


color色彩:Element Plus为了避免视觉传达差异,使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外观视觉感受

主色
 




中性色
中性色用于文本、背景和边框颜色。 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。

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>





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设置容器背景色

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>





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>



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(如果想要直接使用,需要全局注册组件)

安装


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:注册所有图标

需要从@element-plus/icons-vue 中导入所有图标并进行全局注册

  1. Object.entries(ElementPlusIconsVue): 获取 ElementPlusIconsVue 对象中所有的键值对(图标组件)。

  2. for (const [key, component] of ...): 遍历每个图标的键(名称)和对应的组件。

  3. 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使用这些图标。

这样,开发者就可以方便地在应用中使用 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)
}

法2:直接通过浏览器的HTML标签导入Element Plus,然后就能使用全局变量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
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>

基础用法
 

<!-- 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。-->

结合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

通过基础的24分栏,迅速简便创建布局

组件默认使用 Flex 布局,不需要手动设置 type="flex"

请注意父容器避免使用 inline 相关样式,会导致组件宽度不能撑满。

1.el-row 行

el-col 列
<el-col> 组件的 :span 属性用于定义列的宽度

<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>



2.分栏间隔 gutter指定列之间的间距

<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>

  </el-row>
  <el-row :gutter="20">
    <el-col :span="4"><div class="grid-content ep-bg-purple" /></el-col>
    <el-col :span="16"><div class="grid-content ep-bg-purple" /></el-col>
    <el-col :span="4"><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>

space间距

虽然我们拥有 Divider 组件,但很多时候我们需要不是一个被 Divider 组件 分割开的页面结构,因此我们会重复的使用很多的 Divider 组件,这在我们的开发效率上造成了一定的困扰。 间距组件就是为了解决这种困扰应运而生的
