html页面表格导出到excel总结

最近一个项目需要把报表的表格导入excel，在网上找了一些方法，比较研究了一下，记在这里，备忘。

表格例子如下：

<table id="tableExcel" width="100%" border="1" cellspacing="0" cellpadding="0">    <tr>        <td colspan="5" align="center">html 表格导出道Exceltd>    tr>    <tr>        <td>列标题1td>        <td>列标题2td>        <td>类标题3td>        <td>列标题4td>        <td>列标题5td>    tr>    <tr>        <td>aaatd>        <td>bbbtd>        <td>ccctd>        <td>dddtd>        <td>eeetd>    tr>    <tr>        <td>AAAtd>        <td>BBBtd>        <td>CCCtd>        <td>DDDtd>        <td>EEEtd>    tr>    <tr>        <td>FFFtd>        <td>GGGtd>        <td>HHHtd>        <td>IIItd>        <td>JJJtd>   tr>table>

1、js的方法

A、将整个表格拷贝到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、读取表格中每个单元到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、把表格输出到另一个页面，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("你要导出的表不存在");            return;        }        var fileName = getExcelFileName();        doFileExport(fileName, allStr);    }    catch(e) {        alert("导出发生异常:" + 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();}

总结：比较上面3种方法，感觉第一种方法比较完美一些，因为这种方法比较完整的输出表格的格式。但，第一和第二种方法都用了ActiveX 对象，对客户端的安全有要求，而且最大的问题还有一个，就是excel 对象无法关闭。第3中方法虽然没有用ActiveX 对象，但是用了弹出窗口输出， 如果禁止了弹出窗口则无法使用。

对于execl 对象无法关闭的问题，下面的方法是一个权宜方法：

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

调用方法：

idTmr = window.setInterval("Cleanup();",1);

2、Asp.net(c#)中的方法

这种方法其实类似上面的js的第3中方法(也可以在其他的web脚本来实现，比如asp中vbscript，或者php)，把表格用文件流的方式

输出为excel。实例代码如下：

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();    }

这种方法的从本质上说并非标准的excel格式，不过把html格式的文件另存为excel的格式，然后用excel打开罢了。

3、利用ExceL Application或者MSOWC 或者ado.net

这种方法都是利用服务器的组件来时实现，要求服务端要安装excel，具体的代码可以看下面的链接：

我不提倡用这种方法，因为需要占用服务器的资源。
