按需加載
1.對項目進行打包
npm run build
2.安裝babel-plugin-component插件
npm install babel-plugin-component -D
3.將 babel.config.js文件修改為以下內(nèi)容
module.exports = {
presets: [
'@vue/cli-plugin-babel/preset'
],
"plugins": [
[
"component",
{
"libraryName": "element-ui",
"styleLibraryName": "theme-chalk"
}
]
]
}
4.按需在src/main.js文件下引入Button和Message
import Vue from 'vue';
import App from './App.vue';
import 'element-ui/lib/theme-chalk/index.css';
import { Button, Message } from 'element-ui';
Vue.component(Button.name, Button);
/* 或?qū)憺? * Vue.use(Button);
*/
Vue.prototype.$message = Message;
Vue.config.productionTip = false;
new Vue({
render: h => h(App),
}).$mount('#app')

5.重新對項目進行打包
npm run build

全局配置
在引入 Element 時盲憎，可以傳入一個全局配置對象传透。該對象目前支持size與zIndex字段凄敢。size 用于改變組件的默認尺寸，zIndex設置彈框的初始z-index（默認值：2000）庸追。按照引入 Element 的方式霍骄，具體操作如下：
完整引入 Element：
import Vue from 'vue';
import App from './App.vue';
import Element from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
Vue.use(Element, { size: 'small', zIndex: 3000 });
Vue.config.productionTip = false;
new Vue({
render: h => h(App),
}).$mount('#app')
按需引入 Element：
import Vue from 'vue';
import App from './App.vue';
import 'element-ui/lib/theme-chalk/index.css';
import { Button, Message } from 'element-ui';
Vue.prototype.$ELEMENT = { size: 'small', zIndex: 3000 };
Vue.use(Button);
Vue.prototype.$message = Message;
Vue.config.productionTip = false;
new Vue({
render: h => h(App),
}).$mount('#app')
