前言：其实本来是要做全类型文件预览的，但是一直找不到合适的doc,xlx,ppt预览插件。要是有可以使用的，可以评论推荐给我

我使用的node版本：v18.19.1

参考官网：preview 文件预览 | ran

引入方式：

//安装组件
npm install ranui --save
//在需要的页面引入即可
import 'ranui/button';
import 'ranui/preview';
import 'ranui/style';
//使用方式

<div class="preview-container">
    <div id="showPreview" class="preview"></div>
    <r-preview :src="url" closeable="false"></r-preview>
</div>

我这里多了个showPreview用来处理ppt的预览，因为他原生的ppt预览是增加一个弹窗，我需要当前页面展示，样式不符合要求，我就修改了,\node_modules\ranui\dist\components\preview\index.js  里对应第一个文件

修改如下：

var __defProp = Object.defineProperty;
var __defNormalProp = (obj, key, value) => key in obj ? __defProp(obj, key, { enumerable: true, configurable: true, writable: true, value }) : obj[key] = value;
var __publicField = (obj, key, value) => {
  __defNormalProp(obj, typeof key !== "symbol" ? key + "" : key, value);
  return value;
};
