如何將網頁表格內容匯入excel_javascript技巧

//匯出到Excel，注意，表格標記內不得有註釋，因為childNodes會把註釋也算進去
//如果出錯，需要關閉Excel，否則Excel進程會一直運行
//td中只能有一個input值
//非td間不可以有組成否則報缺少“；”錯誤
//引用頁加上
//新增按鈕
//將table表的id和class設定為tableNr
function ExportExcel(btn,TabId,strCols,sTitle,sHeader,sFooter){
//alert('ssss');
btn.style.cursor = "wait";
event.returnValue = false;
//try{
var tab = document.getElementById( TabId);
// if(tab == null) tab = document.getElementById("dg")
//if(tab == null) tab = document.getElementById("db")
//if(tab == null) tab = document.getElementById(TabId)
if(tab == null){
alert("缺少表格物件");

var t = tab.firstChild;
var rows = t.childNodes.length;
