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，然後存成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("你要匯出的表不存在");
return;
}
var fileName = getExcelFileName();
doFileExport(fileName, allStr);
}
catch(e) {
alert("匯出發生異常:" + 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 物件，對客戶端的安全有要求，而且最大的問題還有一個，就是excel 物件無法關閉。第3中方法雖然沒有用ActiveX 物件，但是用了彈出視窗輸出， 如果禁止了彈出視窗則無法使用。
對於execl 物件無法關閉的問題，下面的方法是一個權宜方法：
function Cleanup() {
window.clearInterval(idTmr);
CollectGarbage();
} 呼叫方法：
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指令碼來實現，比如asp中vbscript，或者php)，把表格用檔案流的方式輸出為excel。例項程式碼如下：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並非標準的excel格式，不過把html格式的檔案另存為excel的格式，然後用excel開啟罷了。3、利用ExceL Application或者MSOWC 或者ado.net這種方法都是利用伺服器的元件來時實現，要求服務端要安裝excel，具體的程式碼可以看下面的連結：http://www.cnblogs.com/pucumt/archive/2006/09/13/503120.htmlhttp://support.microsoft.com/default.aspx?scid=kb;zh-cn;306023#top我不提倡用這種方法，因為需要佔用伺服器的資源。
