vue 自定义全局组件 通用流程

1.全局组件的目录

 2.loading/index.js

import LoadingComp from './Loaiding'
const compName=LoadingComp.name //获取组件的名字 当做全局组件名字使用
 
const loading = {
  //Vue.use()方法就会自动执行install
 
  install(Vue) { 
    Vue.component(compName, LoadingComp)
  }
 
}
export default loading

3.loading/Loading.vue

<template>
  <div>
    <h3>{
   
   {loadingMessage}}</h3>
    <h3>{
   
   {aa}}</h3>
  </div>
</template>
<script>
export default {
  name: "Loading",
  props: {
    aa: {
      type: String,
    }
  },
  data() {
    return {
      loadingMessage: "loading..."
    };
  },
  methods: {},
 
};
</script>
<style lang="scss" scoped>
</style>

4.main.js全局注册

import Loading from './components/globalComponents/loading/index'
Vue.use(Loading)

5.使用

<template>
  <div>
    <loading></loading> //无需注册 直接使用
  </div>
</template>

批量导入多个自定义全局组件

 index.js文件(上面globalComponents下面统一新建一个index.js文件)

import loading from './loading'
import mySelect from './myselect'
 
export default {
  loading,
  mySelect
}

//main.js 批量导入全局自定义组件
import globalComponents from './components/globalComponents'
for (let key in globalComponents) {
  Vue.use(globalComponents[key])
}
