前言,因为项目需求需要,我们需要把后端传来的list转成excel模板,并且下载下来)
之前有用的插件,但是会有少0的情况,如下
所以采用另一个项目用过的方法,最终完美实现效果,如下:
1,首先我们来看下后端提供的数据结构
2,具体前端代码如下
封装的组件,需要的同学直接copy就行(这个方法是在 src - mixins -crud.js文件上写的)
import * as XLSX from 'xlsx'; //直接引入就行/*** 导出Excel* @param json 要导出的json数据* @param name 要导出的文件名* @param type 要导出的数据类型* @constructor*/mixinExportJosnToExcel(json, name = 'data', type = 'application/octet-stream') {let wb = { SheetNames: [], Sheets: {}, Props: { }};if (!Array.isArray (json)) {// eslint-disable-next-line no-param-reassignjson = [json];}json.forEach (item => {wb.SheetNames.push (item.sheetName);wb.Sheets[item.sheetName] = XLSX.utils.json_to_sheet (item.sheetValues, item.sheetOptions);});const wopts = { bookType: 'xlsx', bookSST: false, type: 'binary' };// eslint-disable-next-line no-use-before-definelet blob = new Blob ([s2ab (XLSX.write (wb, wopts))], { type });let link = document.createElement ('a');document.body.appendChild (link);link.style.display = 'none';link.href = window.URL.createObjectURL (blob);link.download = `${name}.xlsx`;link.click ();// 释放资源setTimeout (() => {URL.revokeObjectURL (link.href);}, 100);function s2ab(s) {if (typeof ArrayBuffer !== 'undefined') {const buf = new ArrayBuffer (s.length);const view = new Uint8Array (buf);for (let i = 0; i !== s.length; ++i) {view[i] = s.charCodeAt (i) & 0xFF;}return buf;}const buf = new Array (s.length);for (let i = 0; i !== s.length; ++i) {buf[i] = s.charCodeAt (i) & 0xFF;}return buf;}},}
}
举例使用:
html
<div class="prompt_three"@click="downloadList()">下载失败结果</div>现在引入
<script>import crud from "@/mixins/crud";export default {mixins: [crud],}
</script>在方法里
//下载失败清单async downloadList() {try { //这里的模板数据应是从上传之后的确定按钮拿到的let arr = []let telephone=''this.errorList.forEach(one=>{ //this.errorList就是拿到的后端listif(one.serviceConsultantList && one.serviceConsultantList.length>0){one.serviceConsultantList.forEach((two,index) => {console.log(index+1 , one.serviceConsultantList.length)telephone += `${two.telephone}${index+1 == one.serviceConsultantList.length ? '' : '、'}`})}else{telephone=''}arr.push({'酒店code': one.hotelId,'服务顾问姓名':one.nameList && one.nameList.length>0?one.nameList.join("、"):null,'服务顾问联系方式': telephone,'失败原因': one.errorReason,})})const json = {sheetName: '酒店导入失败明细',sheetValues: arr};this.mixinExportJosnToExcel (json,'批量导入员工失败清单');} catch (error) {console.log(error,"error")}},ok,已完
