1、js的方法

A、將整個表格拷貝到EXCEL中

function method1(tableid) {var curTbl = document.getElementById(tableid);var oXL = new ActiveXObject("Excel.Application");var oWB = oXL.Workbooks.Add();var oSheet = oWB.ActiveSheet;var sel = document.body.createTextRange();sel.moveToElementText(curTbl);sel.select();sel.execCommand("Copy");oSheet.Paste();oXL.Visible = true;}

?B、讀取表格中每個單元到EXCEL中：

function method2(tableid) {var curTbl = document.getElementById(tableid);var oXL = new ActiveXObject("Excel.Application");var oWB = oXL.Workbooks.Add();var oSheet = oWB.ActiveSheet;var Lenr = curTbl.rows.length;for (i = 0; i < Lenr; i++){ var Lenc = curTbl.rows(i).cells.length;for (j = 0; j < Lenc; j++){oSheet.Cells(i + 1, j + 1).value = curTbl.rows(i).cells(j).innerText;}}oXL.Visible = true; }

?c、把表格輸出到另一個頁面，然后存成cvs格式

?

function getXlsFromTbl(inTblId, inWindow) {try {var allStr = "";var curStr = "";if (inTblId != null && inTblId != "" && inTblId != "null") {curStr = getTblData(inTblId, inWindow);}if (curStr != null) {allStr += curStr;}else {alert("你要導出的表不存在");return;}var fileName = getExcelFileName();doFileExport(fileName, allStr);}catch(e) {alert("導出發生異常:" + e.name + "->" + e.description + "!");}}function getTblData(inTbl, inWindow) {var rows = 0;var tblDocument = document;if (!!inWindow && inWindow != "") {if (!document.all(inWindow)) {return null;}else {tblDocument = eval(inWindow).document;}}var curTbl = tblDocument.getElementById(inTbl);var outStr = "";if (curTbl != null) {for (var j = 0; j < curTbl.rows.length; j++) {for (var i = 0; i < curTbl.rows[j].cells.length; i++) {if (i == 0 && rows > 0) {outStr += " \t";rows -= 1;}outStr += curTbl.rows[j].cells[i].innerText + "\t";if (curTbl.rows[j].cells[i].colSpan > 1) {for (var k = 0; k < curTbl.rows[j].cells[i].colSpan - 1; k++) {outStr += " \t";}}if (i == 0) {if (rows == 0 && curTbl.rows[j].cells[i].rowSpan > 1) {rows = curTbl.rows[j].cells[i].rowSpan - 1;}}}outStr += "\r\n";}}else {outStr = null;alert(inTbl + "不存在 !");}return outStr; }function getExcelFileName() {var d = new Date();var curYear = d.getYear();var curMonth = "" + (d.getMonth() + 1);var curDate = "" + d.getDate();var curHour = "" + d.getHours();var curMinute = "" + d.getMinutes();var curSecond = "" + d.getSeconds();if (curMonth.length == 1) {curMonth = "0" + curMonth;}if (curDate.length == 1) {curDate = "0" + curDate;}if (curHour.length == 1) {curHour = "0" + curHour;}if (curMinute.length == 1) {curMinute = "0" + curMinute;}if (curSecond.length == 1) {curSecond = "0" + curSecond;}var fileName = "table" + "_" + curYear + curMonth + curDate + "_"+ curHour + curMinute + curSecond + ".csv";return fileName;}function doFileExport(inName, inStr) {var xlsWin = null;if (!!document.all("glbHideFrm")) {xlsWin = glbHideFrm;}else {var width = 6;var height = 4;var openPara = "left=" + (window.screen.width / 2 - width / 2)+ ",top=" + (window.screen.height / 2 - height / 2)+ ",scrollbars=no,width=" + width + ",height=" + height;xlsWin = window.open("", "_blank", openPara);}xlsWin.document.write(inStr);xlsWin.document.close();xlsWin.document.execCommand('Saveas', true, inName);xlsWin.close();}

?總結：比較上面3種方法，感覺第一種方法比較完美一些，因為這種方法比較完整的輸出表格的格式。但，第一和第二種方法都用了 ActiveX 對象，對客戶端的安全有要求，而且最大的問題還有一個，就是excel 對象無法關閉。第3中方法雖然沒有用ActiveX 對象，但是用了彈出窗口輸出，?如果禁止了彈出窗口則無法使用。

對于execl 對象無法關閉的問題，下面的方法是一個權宜方法：

function Cleanup() {window.clearInterval(idTmr);CollectGarbage();}

?調用方法：

idTmr = window.setInterval("Cleanup();",1); 2、Asp.net(c#)中的方法 這種方法其實類似上面的js的第3中方法(也可以在其他的web腳本來實現，比如asp中vbscript，或者php)，把表格用文件流的方式 輸出為excel。實例代碼如下： public void OutPutExcel(string title){Response.Clear();Response.Buffer = true;Response.Charset = "utf-8";Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(title + ".xls"));Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");Response.ContentType = "application/ms-excel";Page.EnableViewState = false;System.IO.StringWriter oStringWriter = new System.IO.StringWriter();System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);this.Page.RenderControl(oHtmlTextWriter);string temp = oStringWriter.ToString();Response.Write(temp);Response.End();} 這種方法的從本質上說并非標準的excel格式，不過把html格式的文件另存為excel的格式，然后用excel打開罷了。 3、利用ExceL Application或者MSOWC 或者ado.net 這種方法都是利用服務器的組件來時實現，要求服務端要安裝excel，具體的代碼可以看下面的鏈接： http://www.cnblogs.com/pucumt/archive/2006/09/13/503120.html http://support.microsoft.com/default.aspx?scid=kb;zh-cn;306023#top 我不提倡用這種方法，因為需要占用服務器的資源。
