JS实现导出Excel和CSV文件操作
一、js导出Excel
<html> <head> </head> <body> <script type="text/javascript" src="./xlsx.core.min.js"></script> <script type="text/javascript"> /** * 通用的打开下载对话框方法,没有测试过具体兼容性 * @param url 下载地址,也可以是一个blob对象,必选 * @param saveName 保存文件名,可选 */ function openDownloadDialog(url, saveName) { if (typeof url == 'object' && url instanceof Blob) { url = URL.createObjectURL(url); // 创建blob地址 } var aLink = document.createElement('a'); aLink.href = url; aLink.download = saveName || ''; // HTML5新增的属性,指定保存文件名,可以不要后缀,注意,file:///模式下不会生效 var event; if (window.MouseEvent) event = new MouseEvent('click'); else { event = document.createEvent('MouseEvents'); event.initMouseEvent('click', true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null); } aLink.dispatchEvent(event); } // 将一个sheet转成最终的excel文件的blob对象,然后利用URL.createObjectURL下载 function sheet2blob(sheet, sheetName) { sheetName = sheetName || 'sheet1'; var workbook = { SheetNames: [sheetName], Sheets: {} }; workbook.Sheets[sheetName] = sheet; // 生成excel的配置项 var wopts = { bookType: 'xlsx', // 要生成的文件类型 bookSST: false, // 是否生成Shared String Table,官方解释是,如果开启生成速度会下降,但在低版本IOS设备上有更好的兼容性 type: 'binary' }; var wbout = XLSX.write(workbook, wopts); var blob = new Blob([s2ab(wbout)], { type: "application/octet-stream" }); // 字符串转ArrayBuffer function s2ab(s) { var buf = new ArrayBuffer(s.length); var view = new Uint8Array(buf); for (var i = 0; i != s.length; ++i) view[i] = s.charCodeAt(i) & 0xFF; return buf; } return blob; } </script> <script type="text/javascript"> var exportDataSource = [{ name: '路人甲', phone: '123456789', email: '000@123456.com' }, { name: '炮灰乙', phone: '123456789', email: '000@123456.com' }, { name: '土匪丙', phone: '123456789', email: '000@123456.com' }, { name: '流氓丁', phone: '123456789', email: '000@123456.com' }, ]; //导出json数据源 function exportExcel() { var excelItems = []; for (let i = 0; i < exportDataSource.length; i++) { if (exportDataSource[i].name != "") { excelItems.push({ "姓名": exportDataSource[i].name, "电话": exportDataSource[i].phone, "邮箱": exportDataSource[i].email }); //属性 } } var sheet = XLSX.utils.json_to_sheet(excelItems); openDownloadDialog(sheet2blob(sheet), 'exportdata.xlsx'); } </script> <a style="float: right;" onclick="exportExcel()">导出下载</a> </body> </html>
二、js实现json导出csv
<html> <head> <p style="font-size: 20px;color: red;">使用a标签方式将json导出csv文件</p> <button onclick='tableToExcel()'>导出</button> </head> <body> <script> function tableToExcel(){ //要导出的json数据 const jsonData = [ { name:'路人甲', phone:'123456789', email:'000@123456.com' }, { name:'炮灰乙', phone:'123456789', email:'000@123456.com' }, { name:'土匪丙', phone:'123456789', email:'000@123456.com' }, { name:'流氓丁', phone:'123456789', email:'000@123456.com' }, ] //列标题,逗号隔开,每一个逗号就是隔开一个单元格 let str = `姓名,电话,邮箱\n`; //增加\t为了不让表格显示科学计数法或者其他格式 for(let i = 0 ; i < jsonData.length ; i++ ){ for(let item in jsonData[i]){ str+=`${jsonData[i][item] + '\t'},`; } str+='\n'; } //encodeURIComponent解决中文乱码 let uri = 'data:text/csv;charset=utf-8,\ufeff' + encodeURIComponent(str); //通过创建a标签实现 let link = document.createElement("a"); link.href = uri; //对下载的文件命名 link.download = "json数据表.csv"; document.body.appendChild(link); link.click(); document.body.removeChild(link); } </script> </body> </html>
三、js实现json导出csv
<html> <head> <p style="font-size: 20px;color: red;">使用table标签方式将json导出xls文件</p> <button onclick='tableToExcel()'>导出</button> </head> <body> <script> function tableToExcel(){ //要导出的json数据 const jsonData = [ { name:'路人甲', phone:'123456', email:'123@123456.com' }, { name:'炮灰乙', phone:'123456', email:'123@123456.com' }, { name:'土匪丙', phone:'123456', email:'123@123456.com' }, { name:'流氓丁', phone:'123456', email:'123@123456.com' }, ] //列标题 let str = '<tr><td>姓名</td><td>电话</td><td>邮箱</td></tr>'; //循环遍历,每行加入tr标签,每个单元格加td标签 for(let i = 0 ; i < jsonData.length ; i++ ){ str+='<tr>'; for(let item in jsonData[i]){ //增加\t为了不让表格显示科学计数法或者其他格式 str+=`<td>${ jsonData[i][item] + '\t'}</td>`; } str+='</tr>'; } //Worksheet名 let worksheet = 'Sheet1' let uri = 'data:application/vnd.ms-excel;base64,'; //下载的表格模板数据 let template = `<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"> <head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet> <x:Name>${worksheet}</x:Name> <x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet> </x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--> </head><body><table>${str}</table></body></html>`; //下载模板 window.location.href = uri + base64(template) } //输出base64编码 function base64 (s) { return window.btoa(unescape(encodeURIComponent(s))) } </script> </body> </html>
四、js实现Tab转为Excel
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>excel 导出测试</title> <style> table { border-collapse: collapse; text-align: center; vertical-align: middle; width: 800px; font-size: 20px; } button { height: 30px; width: 100px; margin: 20px 20px; background: yellowgreen; border-radius: 10px; outline: none; } input { height: 30px; padding-left: 10px; margin: 10px; } </style> </head> <body> <div id="wrap" style="width:900px;margin:20px auto;"> <h3>js脚本 导出excel测试</h3> <table id="tb" border="1" cellspacing="0" cellpadding="0"> <thead> <tr> <th>ID</th> <th>姓名</td> <th>年龄</td> <th>座右铭</th> </tr> </thead> <tbody> <tr> <td>1</td> <td>张三</td> <td>18</td> <td>走的人多了,变成了路。</td> </tr> <tr> <td>2</td> <td>李四</td> <td>88</td> <td>人人都有自己走的路,哪条属于自己呢?</td> </tr> <tr> <td>3</td> <td>王五</td> <td>81</td> <td>走别人的路,让他没道可走!</td> </tr> </tbody> </table> <label> 姓名:<input type="text" autocomplete id="name" placeholder="请输入您的姓名..." > </label> <label> 年龄:<input type="text" autocomplete id="age" placeholder="请输入您的年龄..."> </label> <label> 座右铭:<input type="text" autocomplete id="sex" placeholder="请输入您的座右铭..." > </label> <button id="add">添加信息</button> <button id="out" onclick="btn_export()">导出文件</button> </div> <script src="./xlsx.core.min.js"></script> <script src="./jquery.min.js"></script> <script src="./excel.js"></script> <script> function btn_export() { var table = document.querySelector("#tb"); var sheet = XLSX.utils.table_to_sheet(table); //将一个table对象转换成一个sheet对象 openDownloadDialog(sheet2blob(sheet), 'excel.xlsx'); } var id = $("input").length + 1; $(function() { $("#add").click(function() { var name = $("#name").val(); var age = $("#age").val(); var sex = $("#sex").val(); $("tbody").append("<tr><td>" + id + "</td><td>" + name + "</td> <td>" + age + "</td> <td>" + sex + "</td></tr>"); id++; $("input").val(''); }); }) </script> </body> </html>
