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 對象，對用戶端的安全有要求，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，但是用了快顯視窗輸出， 如果禁止了快顯視窗則無法使用。

對於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。執行個體代碼如下：

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並非標準的excel格式，不過把html格式的檔案另存新檔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連結：

我不提倡用這種方法，因為需要佔用伺服器的資源。
