【vue】前端实现批量导出excel并打包成ZIP
1，下载npm jszip2，js文件需引入Blob.js/* eslint-disable *//* Blob.js* A Blob implementation.* 2014-05-27** By Eli Grey, http://eligrey.com* By Devin Samarin, https://github.com/eboyjr* License: X11/MIT*See LIC
·
思路：通过Export2Excel的部分方法，获取到blob,再将其转给jszip，完成打包
已将代码封装为一个组件，可通过下方gitee下载
gitee地址：https://gitee.com/mw_666/export-excel-zip

压缩包里的Excel

代码
package.json
"file-saver": "^2.0.5",
"jszip": "^3.7.1",
"less": "^3.0.4",
"less-loader": "^5.0.0",
"xlsx": "^0.17.0",
"script-loader": "^0.7.2"
调用页面
<template>
<div>
<div>
<button @click="exportZip">
这是导出excel单个sheet的zip
</button>
<ZipS :data="data1" :templateId='1' :muBan='muBan1' :zipNames='zipNames' ref="child1"/>
</div>
<div>
<button @click="exportZip2">
这是导出excel有多个sheet的zip
</button>
<ZipS :data="data2" :templateId='2' :muBan='muBan2' :zipNames='zipNames' ref="child2"/>
</div>
如果需要自定义sheet，到export2Excel中改
