安装插件

npm install --save @vue-office/docx @vue-office/excel @vue-office/pdf vue-demi

//docx文档预览组件
npm install @vue-office/docx vue-demi
 
//excel文档预览组件
npm install @vue-office/excel vue-demi
 
//pdf文档预览组件
npm install @vue-office/pdf vue-demi

vue的版本是2.6的 还需要安装

@vue/composition-api 

个人使用安装了这个会报错,所以没事安装这个包也可以正常运行 

上代码

<template>
  <div class="app-container-temp">
    <div style="width: 100%; height: 840px; overflow: hidden">
      <vue-office-docx
        v-if="isdocx"
        :src="url"
        @rendered="rendered"
        style="width: 100%; height: 100%"
