//設置數據

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 += '; 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 += "{worksheet}";
excelFile += "</x:Name>";
excelFile += "<x:WorksheetOptions>";
excelFile += "<x:DisplayGridlines/>";
excelFile += "</x:WorksheetOptions>";
excelFile += "</x:ExcelWorksheet>";

excelFile += "</x:ExcelWorkbook>";
excelFile += "</xml>";
excelFile += "<![endif]-->";
excelFile += "</head>";
excelFile += "<body>";
excelFile += excel;
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);
}
調用：
$("#siteDown").click(function () {
//自定義標題欄
var title=['站點編碼','站點名稱']
//自定義過濾欄（不需要導出的行）
// var filter=['id','logins'];
var filter=[];
//原始導出
// JSONToExcelConvertor(data3,"report");
//自定義導出
JSONToExcelConvertor(siteJson,"申請站點",title,filter);
})
