纯前借助word模板端导出word文件（推荐）

这是导出后的效果：

使用模板导出

需要的依赖：
npm 自行安装，需要看官网的具体参数自行去github上面找对应的参数

 	"docxtemplater": "^3.46.0","pizzip": "^3.1.6","jszip-utils": "^0.1.0","file-saver": "^2.0.5",

具体代码：（先看word模板，在看代码，word中的变量和代码中 doc.setData() 是一一对应的）
在这里插入图片描述

<template><div class="button-box"><a-space><a-button type="danger" @click="downWord2">模板导出word文件</a-button></a-space></div>
</template><script lang="ts">
import { defineComponent, onMounted, reactive, PropType, ref } from 'vue';
import { message } from 'ant-design-vue';
import moment from 'moment';
import { downloadPDF } from '../../../../utils/utils';
import { useTable } from './hooks/useTable';
import xlsx from 'node-xlsx';import docxtemplater from 'docxtemplater';
import PizZip from 'pizzip';
import JSZipUtils from 'jszip-utils';
import { saveAs } from 'file-saver';export default defineComponent({props: {/*** 基础数据*/baseData: {type: Object as PropType<{taskId: string;barcodeId: string;}>,default: {},},/*** 样本名称*/barcodeName: {type: String,},},setup(props) {let width = 100;const { barcodeName } = props;const { taskId, barcodeId } = props.baseData;const { tableConfig, tableConfigLeft, getDta } = useTable();onMounted(() => {barcodeName ? getDta(taskId, barcodeName) : '';});const tableValue = reactive({unit: '中国',date: undefined,sampleType: '你猜',people: '黄种人',name: '夜空',sex: '男',age: '25',work: '开发',id: '',jiance: '商品化试剂盒',date2: undefined,});const downWord2 = () => {let docxname = '导出word.docx';JSZipUtils.getBinaryContent('/test.docx', function (error: any, content: any) {// test.docx是模板（这里我放到public公共文件夹下面了）。我们在导出的时候，会根据此模板来导出对应的数据// 抛出异常if (error) {throw error;}// 创建一个PizZip实例，内容为模板的内容let zip = new PizZip(content);// 创建并加载docx templater实例对象let doc = new docxtemplater().loadZip(zip);// 设置模板变量的值  主要变量替换在这里doc.setData({name: tableValue.name,unit: tableValue.unit,date: moment(tableValue.date).format('YYYY-MM-DD'),sampleType: tableValue.sampleType,sex: tableValue.sex,age: tableValue.age,});try {// 用模板变量的值替换所有模板变量doc.render();} catch (error: any) {// 抛出异常let e = {message: error.message,name: error.name,stack: error.stack,properties: error.properties,};console.log(JSON.stringify({error: e,}),);throw error;}// 生成一个代表docxtemplater对象的zip文件（不是一个真实的文件，而是在内存中的表示）let out = doc.getZip().generate({type: 'blob',mimeType: 'application/vnd.openxmlformats-officedocument.wordprocessingml.document',});// 将目标文件对象保存为目标类型的文件，并命名saveAs(out, docxname);});};return {downWord2,getDta,tableConfig,tableConfigLeft,tableValue,downloadPDF,value4: ref('less'),};},

前端通过模板字符串导出word文件

包依赖：

 "file-saver": "^2.0.5",

代码

import FileSaver from 'file-saver';
import htmlDocx from "html-docx-js/dist/html-docx"
