前端实现docx文件预览的3种方式举例及分析

<template>
  <div class="document-wrapper">
    <div class="content" ref="contentRef"></div>
  </div>
</template>

<script lang="ts" setup>
import { ref } from "vue";
import axios from "axios";
import { renderAsync } from 'docx-preview';

const contentRef = ref<any>(null);

function getDocxContent() {
  // 注意：如果是前端本地静态文件，需要放放在public目录下
  axios.get('/test.docx', { responseType: 'arraybuffer' }).then((res) => {
    renderAsync(res.data, contentRef.value);
  }).catch((err) => { console.log(err) })
}
getDocxContent();

</script>

<style lang="less">
.document-wrapper {
  margin: 10px;
}

// 设置word文档的样式
// .docx-wrapper {
//   background: white !important;
//   border: 1px solid red;

//   section {
//     width: 100% !important;
//     padding: 20px !important;
//   }

//   .docx {
//     box-shadow: none !important;
//   }
// }</style>

# docx文档预览，基于docx-preview库实现
npm install @vue-office/docx

# excel文档预览，基于exceljs和x-data-spreadsheet实现，全网样式支持更好
npm install @vue-office/excel

# pdf文档预览，基于pdfjs库实现，实现了虚拟列表增加性能
npm install @vue-office/pdf

# pptx文档预览，基于pptx-preview实现
npm install @vue-office/pptx

<template>
  <div class="document-wrapper">
    <VueOfficeDocx :src="fileData" />
  </div>
</template>

import VueOfficeDocx from '@vue-office/docx'

const fileData = ref<any>(null);

function getDocxContent() {
  // 注意：本地静态文件需要放放在public目录下
  axios.get('/test.docx', { responseType: 'arraybuffer' }).then((res) => {
    fileData.value = res.data;
  }).catch((err) => { console.log(err) })
}
getDocxContent();

</script>

<template>

import mammoth from 'mammoth';

const fileContent = ref<any>(null);

function getDocxContent() {
  axios.get('/test.docx', { responseType: 'arraybuffer' }).then((res) => {
    mammoth.convertToHtml({ arrayBuffer: new Uint8Array(res.data) }).then((res) => {
      fileContent.value = res.value;
    })
  }).catch((err) => { console.log(err) })
}
getDocxContent();
