vue2.0学习笔记之自定义组件

Posted 2020-09-27

• step one:    推荐结构

• step two:    Loading.vue

<template>
    <h3>{{msg}}</h3>
</template>
<script>
    export default {
        data(){
            return {
                msg: "loading"
            }
        }
    }
</script>
<style scoped>
    h3 { color: #699; }
</style>

• step three:     index.js

import LoadingComponent from ‘./Loading.vue‘

const Loading = {
    install: function(Vue){
        Vue.component(‘Loading‘,LoadingComponent)
    }
}

export default Loading

• step four:   main.js

 

import Vue from ‘vue‘
import App from ‘./App.vue‘
import Loading from ‘./components/loading‘  //默认加载index.js

Vue.use(Loading);

new Vue({
  el: ‘#app‘,
  render: h => h(App)
})

最后就可以在App.vue里使用Loading这个自定义组件了：   <loading></loading>
