在日常业务中，有一些没有规律的表格需要导出是，在后端处理会非常麻烦，我们可以把数据提取到html table标签中，然后进行导出
代码如下：
//前端导出excel表格 function ExcelConvertor(data, FileName) { if (FileName == null) { FileName = "下载文件"; } var excelFile = "<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'>"; excelFile += '<meta http-equiv="content-type" content="application/vnd.ms-excel; charset=UTF-8">'; excelFile += '<meta http-equiv="content-type" content="application/vnd.ms-excel'; excelFile += '; charset=UTF-8">'; excelFile += "<head>"; excelFile += "<!--[if gte mso 9]>"; excelFile += "<xml>"; excelFile += "<x:ExcelWorkbook>"; excelFile += "<x:ExcelWorksheets>"; excelFile += "<x:ExcelWorksheet>"; excelFile += "<x:Name>"; excelFile += "worksheet1"; excelFile += "</x:Name>"; excelFile += "<x:WorksheetOptions>"; excelFile += "<x:DisplayGridlines/>"; excelFile += "</x:WorksheetOptions>"; excelFile += "</x:ExcelWorksheet>"; excelFile += "</x:ExcelWorksheets>"; excelFile += "</x:ExcelWorkbook>"; excelFile += "</xml>"; excelFile += "<![endif]-->"; excelFile += "</head>"; excelFile += "<body>"; excelFile += data; excelFile += "</body>"; excelFile += "</html>"; var uri = 'data:application/vnd.ms-excel;charset=utf-8,' + encodeURIComponent(excelFile); var link = document.createElement("a"); link.href = uri; link.style = "visibility:hidden"; link.download = FileName + ".xls"; document.body.appendChild(link); link.click(); document.body.removeChild(link); }
使用场景：
<div id="show-selected" style="display: none;"> <h3 style="float:right;">单位：元</h3> <cs-table :tablekey="tablekey" :tabledata="tabledata"></cs-table> </div>
function Export() { var data = $("#show-selected").html(); ExcelConvertor(data, "文件名"); }
