应用v-if指令来动态创建子组件

子组件中:

<template>    <div>{{value}}</div></template><script>export default {    props: {        value: {            type: String        }    }}</script>

在父组件中:

<template>    <div>        <div v-if="viewReady">            <child v-bind:value=""/>        </div>    <div></template><script>export default {    data() {        return {            viewReady: false        }    },    created() {        this.getData()    },    methods: {        getData() {            return new Promise(r=> {                // request                r()            }).then(res => {                this.viewReady = true            })        }    }}</script>
