element与elementplus入门

news 2025/4/1 14:27:48

注：此篇博客仅是对element官网做个总结，以熟悉基本组件，具体开发还是依据官网教程

element官网地址：Element - The world's most popular Vue UI framework

element-plus官网地址：安装 | Element Plus

1、概述

Element 和 ElementPlus 都是基于 Vue.js 的 UI 组件库。

2、Vue 版本支持

Element：基于 Vue 2 构建

ElementPlus：为 Vue 3 量身打造

3、element的使用

安装

npm 安装

npm i element-ui -S

<!-- 引入样式 -->
<link rel="stylesheet" href="https://unpkg.com/element-ui/lib/theme-chalk/index.css">
<!-- 引入组件库 -->
<script src="https://unpkg.com/element-ui/lib/index.js"></script>

引入 Element

main.js完整引入

import Vue from 'vue';
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
import App from './App.vue';Vue.use(ElementUI);new Vue({el: '#app',render: h => h(App)
});

按需引入（推荐）

首先，安装 babel-plugin-component：

npm install babel-plugin-component -D

然后，将 .babelrc 修改为：

{"presets": [["es2015", { "modules": false }]],"plugins": [["component",{"libraryName": "element-ui","styleLibraryName": "theme-chalk"}]]
}

接下来，如果你只希望引入部分组件，比如 Button 和 Select，那么需要在 main.js 中写入以下内容：

import { Button, Select } from 'element-ui';Vue.use(Button)
Vue.use(Select)

如果是按需导入，建议创建util/element-ui.js用于存放导入组件代码，防止main.js代码臃肿：

element-ui.js

import Vue from 'vue'
import { Button, Select } from 'element-ui';Vue.use(Button)
Vue.use(Select)

main.js

import '@/utils/element-ui'

全局配置

size 用于改变组件的默认尺寸
zIndex 设置弹框的初始 z-index（默认值：2000）

完整引入

import Vue from 'vue';
import Element from 'element-ui';
Vue.use(Element, { size: 'small', zIndex: 3000 });

按需引入

import Vue from 'vue';
import { Button } from 'element-ui';Vue.prototype.$ELEMENT = { size: 'small', zIndex: 3000 };
Vue.use(Button);

组件的布局

网格布局layout

事例：电商管理系统页面排版

标签： <el-col> 与 <el-row>

分栏间隔

<el-row :gutter="20"><el-col :span="6"><div class="grid-content bg-purple"></div></el-col><el-col :span="6"><div class="grid-content bg-purple"></div></el-col><el-col :span="6"><div class="grid-content bg-purple"></div></el-col><el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row><style>.el-row {margin-bottom: 20px;&:last-child {margin-bottom: 0;}}.el-col {border-radius: 4px;}.bg-purple-dark {background: #99a9bf;}.bg-purple {background: #d3dce6;}.bg-purple-light {background: #e5e9f2;}.grid-content {border-radius: 4px;min-height: 36px;}.row-bg {padding: 10px 0;background-color: #f9fafc;}
</style>

混合布局（推荐使用）

<el-row :gutter="20"><el-col :span="16"><div class="grid-content bg-purple"></div></el-col><el-col :span="8"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row :gutter="20"><el-col :span="8"><div class="grid-content bg-purple"></div></el-col><el-col :span="8"><div class="grid-content bg-purple"></div></el-col><el-col :span="4"><div class="grid-content bg-purple"></div></el-col><el-col :span="4"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row :gutter="20"><el-col :span="4"><div class="grid-content bg-purple"></div></el-col><el-col :span="16"><div class="grid-content bg-purple"></div></el-col><el-col :span="4"><div class="grid-content bg-purple"></div></el-col>
</el-row>

分栏偏移（用的较少）

<el-row :gutter="20"><el-col :span="6"><div class="grid-content bg-purple"></div></el-col><el-col :span="6" :offset="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row :gutter="20"><el-col :span="6" :offset="6"><div class="grid-content bg-purple"></div></el-col><el-col :span="6" :offset="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row :gutter="20"><el-col :span="12" :offset="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>

总结

在网格布局中，

<el-row> 和 <el-col>：用于横竖的上下排版，比如分栏间隔使用了四个col，四个盒子竖向从左向右排列，而row则是横向从上往下排列。

:gutter：是 <el-row> 组件的一个绑定属性，它接收一个数值类型的值，表示列之间的间距大小，单位是像素（px）。

:span ：该属性定义了每一列在 24 栏栅系统中所占的宽度。

:offset： col 组件的 offset 属性可以指定分栏偏移的栏数

</script>

标签：<el-checkbox> <el-checkbox-group> </el-checkbox-group>

属性：

checkbox

事件：change

form表单-input输入框（常用）

基础用法

示例：

<el-input v-model="input" placeholder="请输入内容"></el-input><script>
export default {data() {return {input: ''}}
}
</script>

可清空输入框-使用clearable属性提供一个清空按钮

<el-inputplaceholder="请输入内容"v-model="input"clearable>
</el-input><script>export default {data() {return {input: ''}}}
</script>

密码框-使用show-password属性即可得到一个可切换显示隐藏的密码框

示例：

<el-input placeholder="请输入密码" v-model="input" show-password></el-input><script>export default {data() {return {input: ''}}}
</script>

带icon的输入框

示例：

<div class="demo-input-suffix">属性方式：<el-inputplaceholder="请选择日期"suffix-icon="el-icon-date"v-model="input1"></el-input><el-inputplaceholder="请输入内容"prefix-icon="el-icon-search"v-model="input2"></el-input>
</div>
<div class="demo-input-suffix">slot 方式：<el-inputplaceholder="请选择日期"v-model="input3"><i slot="suffix" class="el-input__icon el-icon-date"></i></el-input><el-inputplaceholder="请输入内容"v-model="input4"><i slot="prefix" class="el-input__icon el-icon-search"></i></el-input>
</div><script>
export default {data() {return {input1: '',input2: '',input3: '',input4: ''}}
}
</script>

文本域-type="textarea"

自适应文本域-设置 autosize 属性可以使得文本域的高度能够根据文本内容自动进行调整

示例：

<el-inputtype="textarea":rows="2"placeholder="请输入内容"v-model="textarea">
</el-input><script>
export default {data() {return {textarea: ''}}
}
</script>

复合型输入框-通过 slot 来指定在 input 中前置或者后置内容

示例：

<div><el-input placeholder="请输入内容" v-model="input1"><template slot="prepend">Http://</template></el-input>
</div>
<div style="margin-top: 15px;"><el-input placeholder="请输入内容" v-model="input2"><template slot="append">.com</template></el-input>
</div>
<div style="margin-top: 15px;"><el-input placeholder="请输入内容" v-model="input3" class="input-with-select"><el-select v-model="select" slot="prepend" placeholder="请选择"><el-option label="餐厅名" value="1"></el-option><el-option label="订单号" value="2"></el-option><el-option label="用户电话" value="3"></el-option></el-select><el-button slot="append" icon="el-icon-search"></el-button></el-input>
</div>
<style>.el-select .el-input {width: 130px;}.input-with-select .el-input-group__prepend {background-color: #fff;}
</style>
<script>
export default {data() {return {input1: '',input2: '',input3: '',select: ''}}
}
</script>

示例：

<el-inputtype="text"placeholder="请输入内容"v-model="text"maxlength="10"show-word-limit
>
</el-input>
<div style="margin: 20px 0;"></div>
<el-inputtype="textarea"placeholder="请输入内容"v-model="textarea"maxlength="30"show-word-limit
>
</el-input><script>
export default {data() {return {text: '',textarea: ''}}
}
</script>

属性：

可通过 size 属性指定输入框的尺寸，除了默认的大小外，还提供了 medium、small 和 mini 三种尺寸
maxlength 和 minlength 是原生属性，用来限制输入框的字符长度，其中字符长度是用 Javascript 的字符串长度统计的。对于类型为 text 或 textarea 的输入框，在使用 maxlength 属性限制最大输入长度的同时，可通过设置 show-word-limit 属性来展示字数统计。

带输入建议-<el-autocomplete>

示例：

<el-row class="demo-autocomplete"><el-col :span="12"><div class="sub-title">激活即列出输入建议</div><el-autocompleteclass="inline-input"v-model="state1":fetch-suggestions="querySearch"placeholder="请输入内容"@select="handleSelect"></el-autocomplete></el-col><el-col :span="12"><div class="sub-title">输入后匹配输入建议</div><el-autocompleteclass="inline-input"v-model="state2":fetch-suggestions="querySearch"placeholder="请输入内容":trigger-on-focus="false"@select="handleSelect"></el-autocomplete></el-col>
</el-row>
<script>export default {data() {return {restaurants: [],state1: '',state2: ''};},methods: {querySearch(queryString, cb) {var restaurants = this.restaurants;var results = queryString ? restaurants.filter(this.createFilter(queryString)) : restaurants;// 调用 callback 返回建议列表的数据cb(results);},createFilter(queryString) {return (restaurant) => {return (restaurant.value.toLowerCase().indexOf(queryString.toLowerCase()) === 0);};},loadAll() {return [{ "value": "三全鲜食（北新泾店）", "address": "长宁区新渔路144号" },{ "value": "Hot honey 首尔炸鸡（仙霞路）", "address": "上海市长宁区淞虹路661号" },{ "value": "新旺角茶餐厅", "address": "上海市普陀区真北路988号创邑金沙谷6号楼113" },{ "value": "泷千家(天山西路店)", "address": "天山西路438号" },{ "value": "胖仙女纸杯蛋糕（上海凌空店）", "address": "上海市长宁区金钟路968号1幢18号楼一层商铺18-101" },{ "value": "贡茶", "address": "上海市长宁区金钟路633号" },{ "value": "豪大大香鸡排超级奶爸", "address": "上海市嘉定区曹安公路曹安路1685号" },{ "value": "茶芝兰（奶茶，手抓饼）", "address": "上海市普陀区同普路1435号" },{ "value": "十二泷町", "address": "上海市北翟路1444弄81号B幢-107" },{ "value": "星移浓缩咖啡", "address": "上海市嘉定区新郁路817号" },{ "value": "阿姨奶茶/豪大大", "address": "嘉定区曹安路1611号" },{ "value": "新麦甜四季甜品炸鸡", "address": "嘉定区曹安公路2383弄55号" },{ "value": "Monica摩托主题咖啡店", "address": "嘉定区江桥镇曹安公路2409号1F，2383弄62号1F" },{ "value": "浮生若茶（凌空soho店）", "address": "上海长宁区金钟路968号9号楼地下一层" },{ "value": "NONO JUICE  鲜榨果汁", "address": "上海市长宁区天山西路119号" },{ "value": "CoCo都可(北新泾店）", "address": "上海市长宁区仙霞西路" },{ "value": "快乐柠檬（神州智慧店）", "address": "上海市长宁区天山西路567号1层R117号店铺" },{ "value": "Merci Paul cafe", "address": "上海市普陀区光复西路丹巴路28弄6号楼819" },{ "value": "猫山王（西郊百联店）", "address": "上海市长宁区仙霞西路88号第一层G05-F01-1-306" },{ "value": "枪会山", "address": "上海市普陀区棕榈路" },{ "value": "纵食", "address": "元丰天山花园(东门) 双流路267号" },{ "value": "钱记", "address": "上海市长宁区天山西路" },{ "value": "壹杯加", "address": "上海市长宁区通协路" },{ "value": "唦哇嘀咖", "address": "上海市长宁区新泾镇金钟路999号2幢（B幢）第01层第1-02A单元" },{ "value": "爱茜茜里(西郊百联)", "address": "长宁区仙霞西路88号1305室" },{ "value": "爱茜茜里(近铁广场)", "address": "上海市普陀区真北路818号近铁城市广场北区地下二楼N-B2-O2-C商铺" },{ "value": "鲜果榨汁（金沙江路和美广店）", "address": "普陀区金沙江路2239号金沙和美广场B1-10-6" },{ "value": "开心丽果（缤谷店）", "address": "上海市长宁区威宁路天山路341号" },{ "value": "超级鸡车（丰庄路店）", "address": "上海市嘉定区丰庄路240号" },{ "value": "妙生活果园（北新泾店）", "address": "长宁区新渔路144号" },{ "value": "香宜度麻辣香锅", "address": "长宁区淞虹路148号" },{ "value": "凡仔汉堡（老真北路店）", "address": "上海市普陀区老真北路160号" },{ "value": "港式小铺", "address": "上海市长宁区金钟路968号15楼15-105室" },{ "value": "蜀香源麻辣香锅（剑河路店）", "address": "剑河路443-1" },{ "value": "北京饺子馆", "address": "长宁区北新泾街道天山西路490-1号" },{ "value": "饭典*新简餐（凌空SOHO店）", "address": "上海市长宁区金钟路968号9号楼地下一层9-83室" },{ "value": "焦耳·川式快餐（金钟路店）", "address": "上海市金钟路633号地下一层甲部" },{ "value": "动力鸡车", "address": "长宁区仙霞西路299弄3号101B" },{ "value": "浏阳蒸菜", "address": "天山西路430号" },{ "value": "四海游龙（天山西路店）", "address": "上海市长宁区天山西路" },{ "value": "樱花食堂（凌空店）", "address": "上海市长宁区金钟路968号15楼15-105室" },{ "value": "壹分米客家传统调制米粉(天山店)", "address": "天山西路428号" },{ "value": "福荣祥烧腊（平溪路店）", "address": "上海市长宁区协和路福泉路255弄57-73号" },{ "value": "速记黄焖鸡米饭", "address": "上海市长宁区北新泾街道金钟路180号1层01号摊位" },{ "value": "红辣椒麻辣烫", "address": "上海市长宁区天山西路492号" },{ "value": "(小杨生煎)西郊百联餐厅", "address": "长宁区仙霞西路88号百联2楼" },{ "value": "阳阳麻辣烫", "address": "天山西路389号" },{ "value": "南拳妈妈龙虾盖浇饭", "address": "普陀区金沙江路1699号鑫乐惠美食广场A13" }];},handleSelect(item) {console.log(item);}},mounted() {this.restaurants = this.loadAll();}}
</script>

自定义输入建议显示-使用scoped slot自定义输入建议的模板。该 scope 的参数为item，表示当前输入建议对象。

示例：

<el-autocompletepopper-class="my-autocomplete"v-model="state":fetch-suggestions="querySearch"placeholder="请输入内容"@select="handleSelect"><iclass="el-icon-edit el-input__icon"slot="suffix"@click="handleIconClick"></i><template slot-scope="{ item }"><div class="name">{{ item.value }}</div><span class="addr">{{ item.address }}</span></template>
</el-autocomplete><style>

兼容性

安装

npm install element-plus --saveyarn add element-pluspnpm install element-plus

按需引入组件

首先你需要安装unplugin-vue-components 和 unplugin-auto-import这两款插件

npm install -D unplugin-vue-components unplugin-auto-import

然后把下列代码插入到你的 Vite 或 Webpack 的配置文件中

vite.config.ts

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: [// ...AutoImport({resolvers: [ElementPlusResolver()],}),Components({resolvers: [ElementPlusResolver()],}),],
})

webpack.config.js

const AutoImport = require('unplugin-auto-import/webpack')
const Components = require('unplugin-vue-components/webpack')
const { ElementPlusResolver } = require('unplugin-vue-components/resolvers')module.exports = {// ...plugins: [AutoImport({resolvers: [ElementPlusResolver()],}),Components({resolvers: [ElementPlusResolver()],}),],
}

在 src/main.js 或 src/main.ts 中引入 ElementPlus 的样式：

import { createApp } from 'vue'
import App from './App.vue'// 引入 ElementPlus 样式
import 'element-plus/dist/index.css'const app = createApp(App)
app.mount('#app')

在你的 Vue 组件中直接使用 ElementPlus 组件，无需手动导入：

<template><div><el-button>点击我</el-button></div>
</template><script setup>
// 无需手动导入组件
</script>
