.net 将页面的table以excel形式导出
亲测有效
js代码如下 ，引用tableToExcel方法即可，参数为页面table的id属性
function base64(content) {
return window.btoa(unescape(encodeURIComponent(content)));
}
function tableToExcel(tableID) {
var excelContent = $("#" + tableID).html();
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"><meta http-equiv="content-type" content="application/vnd.ms-excel; charset=UTF-8"><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>';
excelFile += "<body><table width='10%' border='1'>";
excelFile += excelContent;
excelFile += "</table></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 = "导出的excel名称.xls";
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
}
