<!-- ModalPopupComp.vue 有disabled -->
<template>
<button @click="ModalOpen = true">弹出一个模态窗口</button>
<!-- 加上 disabled,teleport 功能失效,插槽内容将不会被移动到任何位置,
而是在引用了 teleport 的父组件中渲染。 -->
<teleport to="body" disabled>
<div v-if="ModalOpen" class="modal">
<div class="modal-inner">
<div>这是一个模态弹窗,我的父元素是body。</div>
<button @click="ModalOpen = false">关闭</button>
</div>
