Vue3.0之引入Element-plus ui样式的两种方法
目录
- 第一种:CDN
- 第二种:通过 npm 安装,并希望配合 webpack 使用
npm install element-plus --save
第一种:CDN
目前可以通过 unpkg.com/element-plus 获取到最新版本的资源,在页面上引入 js 和 css 文件即可开始使用。
<! – 引入样式 -->
< link rel=“stylesheet” href=“https://unpkg.com/element-plus/lib/theme-chalk/index.css”>
<! – 引入组件库 -->
< script src=“https://unpkg.com/element-plus/lib/index.full.js”></ script>

第二种:通过 npm 安装,并希望配合 webpack 使用
- vue-cli@4.5:新版的 vue-cli 准备了相应的 Element Plus 插件,你可以用它们快速地搭建一个基于 Element Plus 的项目。
- 引入整个 Element Plus,或是根据需要仅引入部分组件。我们先介绍如何引入完整的 Element。
main.js 中写入以下内容:
import { createApp } from 'vue' import ElementPlus from 'element-plus'; import 'element-plus/lib/theme-chalk/index.css'; import App from './App.vue'; const app = createApp(App) app.use(ElementPlus) app.mount('#app')
以上代码便完成了 Element Plus 的引入。需要注意的是,样式文件需要单独引入。
之后就可以进行样式的按需引入使用了
<template> <div id="app"> <el-button>{{ message }}</el-button> <el-button @click="show = !show">Click Me</el-button> <div style="display: flex; margin-top: 20px; height: 100px;"> <transition name="el-fade-in-linear"> <div v-show="show" class="transition-box">.el-fade-in-linear</div> </transition> <transition name="el-fade-in"> <div v-show="show" class="transition-box">.el-fade-in</div> </transition> </div> <el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm"> <el-form-item label="活动名称" prop="name"> <el-input v-model="ruleForm.name"></el-input> </el-form-item> <el-form-item label="活动区域" prop="region"> <el-select v-model="ruleForm.region" placeholder="请选择活动区域"> <el-option label="区域一" value="shanghai"></el-option> <el-option label="区域二" value="beijing"></el-option> </el-select> </el-form-item> <el-form-item label="活动时间" required> <el-col :span="11"> <el-form-item prop="date1"> <el-date-picker type="date" placeholder="选择日期" v-model="ruleForm.date1" style="width: 100%;"></el-date-picker> </el-form-item> </el-col> <el-col class="line" :span="2">-</el-col> <el-col :span="11"> <el-form-item prop="date2"> <el-time-picker placeholder="选择时间" v-model="ruleForm.date2" style="width: 100%;"></el-time-picker> </el-form-item> </el-col> </el-form-item> <el-form-item label="即时配送" prop="delivery"> <el-switch v-model="ruleForm.delivery"></el-switch> </el-form-item> <el-form-item label="活动性质" prop="type"> <el-checkbox-group v-model="ruleForm.type"> <el-checkbox label="美食/餐厅线上活动" name="type"></el-checkbox> <el-checkbox label="地推活动" name="type"></el-checkbox> <el-checkbox label="线下主题活动" name="type"></el-checkbox> <el-checkbox label="单纯品牌曝光" name="type"></el-checkbox> </el-checkbox-group> </el-form-item> <el-form-item label="特殊资源" prop="resource"> <el-radio-group v-model="ruleForm.resource"> <el-radio label="线上品牌商赞助"></el-radio> <el-radio label="线下场地免费"></el-radio> </el-radio-group> </el-form-item> <el-form-item label="活动形式" prop="desc"> <el-input type="textarea" v-model="ruleForm.desc"></el-input> </el-form-item> <el-form-item> <el-button type="primary" @click="submitForm('ruleForm')">立即创建</el-button> <el-button @click="resetForm('ruleForm')">重置</el-button> </el-form-item> </el-form> </div> </template> <script> export default { data() { return { message:'welcome to here', show:true, ruleForm: { name: '', region: '', date1: '', date2: '', delivery: false, type: [], resource: '', desc: '' }, rules: { name: [ { required: true, message: '请输入活动名称', trigger: 'blur' }, { min: 3, max: 5, message: '长度在 3 到 5 个字符', trigger: 'blur' } ], region: [ { required: true, message: '请选择活动区域', trigger: 'change' } ], date1: [ { type: 'date', required: true, message: '请选择日期', trigger: 'change' } ], date2: [ { type: 'date', required: true, message: '请选择时间', trigger: 'change' } ], type: [ { type: 'array', required: true, message: '请至少选择一个活动性质', trigger: 'change' } ], resource: [ { required: true, message: '请选择活动资源', trigger: 'change' } ], desc: [ { required: true, message: '请填写活动形式', trigger: 'blur' } ] } }; }, methods: { submitForm(formName) { this.$refs[formName].validate((valid) => { if (valid) { const use = { name:this.ruleForm.name, age:this.ruleForm.region } console.log(use) alert('submit!'); } else { console.log('error submit!!'); return false; } }); }, resetForm(formName) { this.$refs[formName].resetFields(); } } } </script> <style> .transition-box { margin-bottom: 10px; width: 200px; height: 100px; border-radius: 4px; background-color: #409EFF; text-align: center; color: #fff; padding: 40px 20px; box-sizing: border-box; margin-right: 20px; } </style>
