前端Vue.js实现json数据导出到doc
作者:baldwin
这篇文章主要介绍了前端Vue.js实现json数据导出到doc,文章围绕主题展开详细的内容介绍,具有一定的参考价值,需要的小伙伴可以参考一下
前言:
先说下需求:如何批量导出表格中勾选的数据,导出格式为word,并具有一定的格式!
开发环境:vue3、node v14.15.0
组件选择
因为导出word需要保留一定的格式,所以这里选择docxtemplater
,利用定制导出模板的方式限制数据的导出格式。
实现一个最简单的导出
安装(后续的demo依赖相同)
yarn add docxtemplater pizzip file-saver
用法:
onst PizZip = require("pizzip"); const Docxtemplater = require("docxtemplater"); const fs = require("fs"); const path = require("path"); // Load the docx file as binary content const content = fs.readFileSync( path.resolve(__dirname, "input.docx"), "binary" ); const zip = new PizZip(content); const doc = new Docxtemplater(zip, { paragraphLoop: true, linebreaks: true, }); // Render the document (Replace {first_name} by John, {last_name} by Doe, ...) doc.render({ first_name: "John", last_name: "Doe", phone: "0652455478", description: "New Website", }); const buf = doc.getZip().generate({ type: "nodebuffer", // compression: DEFLATE adds a compression step. // For a 50MB output document, expect 500ms additional CPU time compression: "DEFLATE", });
单条数据导出到word
配置导出模板,并上传CDN,模板格式如下:
导出的数据结构:
{ "title": "第一篇", "gradeId": "三年级上", "genreDesc": "议论文", "subjectMatterInfo": "叙事", "content": "\t一个晴朗的星期天,爸爸和妈妈带我到北海公园去玩儿。那天秋高气爽,太阳在蓝", "remark": "点评1" }

具体实现:
import Docxtemplater from 'docxtemplater'; import PizZip from 'pizzip'; import PizZipUtils from 'pizzip/utils/index.js'; import {saveAs} from 'file-saver'; function loadFile(url, callback) { PizZipUtils.getBinaryContent(url, callback); } export const renderDoc = data => { loadFile('你上传导出模板的CDN链接.docx', (error, content) => { if (error) { throw error; } const zip = new PizZip(content); const doc = new Docxtemplater(zip, {linebreaks: true}); doc.setData(data); try { // render the document (replace all occurences of {first_name} by John, {last_name} by Doe, ...) doc.render(); } catch (error) { // The error thrown here contains additional information when logged with JSON.stringify (it contains a properties object containing all suberrors). function replaceErrors(key, value) { if (value instanceof Error) { return Object.getOwnPropertyNames(value).reduce((error, key) => { error[key] = value[key]; return error; }, {}); } return value; } console.log(JSON.stringify({error}, replaceErrors)); if (error.properties && error.properties.errors instanceof Array) { const errorMessages = error.properties.errors .map(error => error.properties.explanation) .join('\n'); console.log('errorMessages', errorMessages); // errorMessages is a humanly readable message looking like this : // 'The tag beginning with "foobar" is unopened' } throw error; } const out = doc.getZip().generate({ type: 'blob', mimeType: 'application/vnd.openxmlformats-officedocument.wordprocessingml.document', }); // Output the document using Data-URI saveAs(out, '导出word.docx'); }); };
批量数据导出到wrod
配置导出模板,并上传CDN,模板格式如下:
#articles为循环开始,/为循环结束,中间是循环体
导出的数据结构:
{ "articles": [ { "title": "第一篇", "gradeId": "三年级上", "genreDesc": "议论文", "subjectMatterInfo": "叙事", "content": "\t一个晴朗的星期天,爸爸和妈妈带我到北海公园去玩儿。那天秋高气爽,太阳在蓝", "remark": "点评1" }, { "title": "第二篇", "gradeId": "三年级下", "genreDesc": "记叙文", "subjectMatterInfo": "写人", "content": "\t一个晴朗的星期天,爸爸和妈妈带我到北海公园去玩儿妈带我到北海公园去玩儿。那天秋高气爽,太阳在蓝。\n问女何所思,问女何所忆。女亦无所思,女亦无所忆。昨夜见军帖,可汗大点兵,军书十二卷,卷卷有爷名。阿爷无大儿,木兰无长兄,愿为市鞍马,从此替爷征。问女何所思,问女何所忆。女亦无所思,女亦无所忆。昨夜见军帖,可汗大点兵,军书十二卷,卷卷有爷名。阿爷无大儿,木兰无长兄,愿为市鞍马,从此替爷征。", "remark": "点评2" } ] }
