这篇“vue3.2+ts如何实现在方法中可调用的拟态框弹窗”文章的知识点大部分人都不太理解，所以小编给大家总结了以下内容，内容详细，步骤清晰，具有一定的借鉴价值，希望大家阅读完这篇文章能有所收获，下面我们一起来看看这篇“vue3.2+ts如何实现在方法中可调用的拟态框弹窗”文章吧。
直接上图。
解决代码如下：
import { createApp } from 'vue'
import MessageBoxVue from './MessageBox.vue' \你写的拟态框样式
export const MessageBox = (text: any) => {
return new Promise((resolve, reject) => {
const capp = createApp(MessageBoxVue, text)
const container = document.createElement('div')
const instance = capp.mount(container)
document.body.insertBefore(container, document.body.firstChild)//插入到body最前面，层级更高
instance.callback = (val: any) => {
if (val) {
resolve(val)
} else {
reject()
}
capp.unmount()//注销
document.body.removeChild(container)//点击后清除弹窗
}
instance.close = () => {
capp.unmount()
document.body.removeChild(container)
}
})
}//重点在这儿
//这边相当于把数据当方法使了。我也不知道什么原理。在上面那边就是能接收到回调。
const cancel = () => {
callback.value(false)
}
const confirm = () => {
callback.value(true)
}
const closeBox = () => {
close.value()
}
//抛出这两个方法？反正这个方法不可或缺。
defineExpose({
callback,
close
})\这一段是上面的那个messagebox
<template>

</style>引入全局后的调用
// 使用：
// 在main.ts全局引入，也可以按需引入这里展示全局引入
import {MessageBox} from 'base/src/components/MessageBox/index'
// 注册:
app.config.globalProperties.$messageBox = MessageBox
// 引用:
import { getCurrentInstance } from 'vue'
const { proxy } = getCurrentInstance()
const fn = ()=>{
proxy
.$messageBox({
//这边就是传你在MessageBox的props定义的父传子的数据了
