- 使用PPTXjs做ppt预览，有完整的代码包，基于jquery
- vue3使用iframe引入用于预览ppt的网页，通过url参数传递需要预览的ppt链接
- 通过网页选择文件上传也可以通过下面的函数把文件转换成链接，实现在文件上传到服务器前就可以预览
URL.createObjectURL(file);
ppt/Index.vue:
<template><div class="page-container m-ppt-wrap" id="page-contaninder" ref="pageContaninderRef"><div><input type="file" @change="handleFileChange" /></div><iframe class="m-iframe" :src="iframeUrl"></iframe></div>
</template><script setup lang="ts">
