Vue3.0之引入Element-plus ui样式的两种方法
时间：2022-08-01 10:48:40 | 栏目：vue | 点击：次
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>

<meta name="viewport" content="width=device-width,initial-scale=1.0" />
<script src="https://unpkg.com/vue@next"></script>
<!-- import CSS -->
<link rel="stylesheet" href="https://unpkg.com/element-plus/lib/theme-chalk/index.css" rel="external nofollow" >
<!-- import JavaScript -->
<script src="https://unpkg.com/element-plus/lib/index.full.js"></script>
<title>Element Plus demo</title>
</head>
<body>
<div id="app">
<el-button>{{ message }}</el-button>
</div>
<script>
const App = {
data() {
return {
message: "Hello Element Plus",
};
},
};
const app = Vue.createApp(App);
app.use(ElementPlus);
app.mount("#app");
</script>
</body>
</html>
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
