vue 自定义全局组件

此案例以按钮为demo(由来: elementUI中的按钮点击事件中嵌套messageBox 消息弹框时,点击键盘enter键自动触发弹框,容易误操作 )

src 目录下创建components 文件夹  components里面创建 install.js和 组件目录

install.js里面

// 组件全局注册
import Vue from 'vue'

import edpBtn from '@/components/edpBtn/edpBtn.vue'//封装共用组件方法一
//import AppToolbar from './AppToolbar'

// 组件库
const Components = [
edpBtn
//AppToolbar,
]

// 注册全局组件
Components.map((com) => {
Vue.component(com.name, com)
})

export default Vue

edpBtn.vue edp 公司简称

main.js 中添加   import './components/install'
