实现代码如下：
<script language="javascript" type="text/javascript"><!--
function readExcel() {
var excelApp;
var excelWorkBook;
var excelSheet;
try{
excelApp = new ActiveXObject("Excel.Application");
excelWorkBook = excelApp.Workbooks.open("C:\\XXX.xls");
excelSheet = oWB.ActiveSheet; //WorkSheets("sheet1")
excelSheet.Cells(6,2).value;//cell的值
excelSheet.usedrange.rows.count;//使用的行数
excelWorkBook.Worksheets.count;//得到sheet的个数
excelSheet=null;
excelWorkBook.close();
excelApp.Application.Quit();
excelApp=null;
}catch(e){
if(excelSheet !=null || excelSheet!=undefined){
excelSheet =nul;
}
if(excelWorkBook != null || excelWorkBook!=undefined){
excelWorkBook.close();
}
if(excelApp != null || excelApp!=undefined){
excelApp.Application.Quit();
excelApp=null;
}
}
// --></script>
实现代码如下：
如果是在网页上打开EXCEL 文件，那么在关闭的时候，进程里还有EXCEL.EXE，所以必须关闭后，刷新本页面！
<script>
function ReadExcel()
{
var tempStr = "";
var filePath= document.all.upfile.value;
var oXL = new ActiveXObject("Excel.application");
var oWB = oXL.Workbooks.open(filePath);
oWB.worksheets(1).select();
var oSheet = oWB.ActiveSheet;
try{
for(var i=2;i<46;i++)
{
if(oSheet.Cells(i,2).value =="null" || oSheet.Cells(i,3).value =="null" )
break;
var a = oSheet.Cells(i,2).value.toString()=="undefined"?"":oSheet.Cells(i,2).value;
tempStr+=(" "+oSheet.Cells(i,2).value+
" "+oSheet.Cells(i,3).value+
" "+oSheet.Cells(i,4).value+
" "+oSheet.Cells(i,5).value+
" "+oSheet.Cells(i,6).value+"\n");
}
}catch(e)
{
document.all.txtArea.value = tempStr;
}
document.all.txtArea.value = tempStr;
oXL.Quit();
CollectGarbage();
}
</script>
<html>
<input type="file" id="upfile" /><input type="button" onclick="ReadExcel();" value="read">
<br>
<textarea id="txtArea" cols=50 rows=10></textarea>
</html>
二、
js读取excel文件
实现代码如下：
<script>
function readThis(){
var tempStr = "";
var filePath= document.all.upfile.value;
var oXL = new ActiveXObject("Excel.application");
var oWB = oXL.Workbooks.open(filePath);
oWB.worksheets(1).select();
var oSheet = oWB.ActiveSheet;
try{
for(var i=2;i<46;i++){
if(oSheet.Cells(i,2).value =="null" || oSheet.Cells(i,3).value =="null" )
break;
var a = oSheet.Cells(i,2).value.toString()=="undefined"?"":oSheet.Cells(i,2).value;
tempStr+=(" "+oSheet.Cells(i,2).value+" "+oSheet.Cells(i,3).value+" "+oSheet.Cells(i,4).value+" "+oSheet.Cells(i,5).value+" "+oSheet.Cells(i,6).value+"\n");
}
}
catch(e){
//alert(e);
document.all.txtArea.value = tempStr;
}
document.all.txtArea.value = tempStr; oXL.Quit();
CollectGarbage();
}
</script>
<html>
<input type="file" id="upfile" />
<input type="button" onclick="readThis();" value="读取"><br>
<textarea id="txtArea" cols=50 rows=10></textarea>
</html>
三、
我在vs2005平台上要实现这么一个功能，点击一个按钮一次将大量的excel文件数据导入到sqlserver2005中
我用的是ajax技术，在前台用javascript操做excel文件，循环读取所有的excel文件，每读取一行就放进一个数组里通过web服务传到后台用c#语言将一行数据插入到数据库。思路大概就是这样。
现在功能已经实现了，具体代码如下
用javascript定义一个函数，循环读取excel文件数据
实现代码如下：
function readExcel()
{
try
{
var ExcelNum=new Array();
//重复导入之前，删除上次导入的同期数据
WebServiceExcel.deleteOldNumber();
var oXL = new ActiveXObject( "Excel.Application ");
\\r_c_num[5]的值为excel文件的名字
var path=document.all.excelpath.value+ "\\ "+r_c_num[5]
var oWB = oXL.Workbooks.open(path);
\\如果excel文件有多个sheet的话从第一个sheet循环读取
for(var x=1;x <=oWB.worksheets.count;x++)
{
oWB.worksheets(x).select();
var oSheet =oWB.ActiveSheet;
\\按指定开始行和开始列读取excel文件的数据
for(var i=parseInt(r_c_num[6]);i <=parseInt(r_c_num[7]);i++)
{
for(var j=parseInt(r_c_num[8]);j <=parseInt(r_c_num[9]);j++)
{
if(typeof(oSheet.Cells(i,j).value)== "undefined ")
{
ExcelNum[j-parseInt(r_c_num[8])+6]= " ";
}
else
{
switch_letter(j);
ExcelNum[j-parseInt(r_c_num[8])+6]=oSheet.Cells(i,j).value；
}
}
//将读取的一行数据传到后台插入到数据库
WebServiceExcel.insert_From_Excel(ExcelNum);
}
}
}
}
catch(err)
{
alert( "出错了, "+err.message);
}
}
这只是前台的关键代码。
现在的问题是，如果excel文件数据太多的话，导入过程要等好长时间，性能太差了，不知道该怎么改进？？？如果导几千行数据就不行了，时间让我无法忍受。请高手赐教，很着急用，谢谢了！！！
一个用JavaScript结合Excel.Application读取本地excel文件并以表格呈现的简单例子
实现代码如下：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> New Document </TITLE>
<SCRIPT LANGUAGE="JavaScript">
<!--
var excelFileName = "E:/project/eomstools/ShowTaskCodeWorkbook/test.xls";
var oWB;
function showExcel(targetDIVID){
//objID为表格ID
//需要在浏览器安全级别设置中启用ActiveX
// Start Excel and get Application object.
var oXL=null;
try{
oXL = new ActiveXObject("Excel.Application");
}catch(e){
alert(e.message);
return ;
}
if (oXL == null){
alert("创建Excel文件失败，可能是您的计算机上没有正确安装Microsoft Office Excel软件或浏览器的安全级别设置过高！");
return;
}
try{
// Get a new workbook.
oWB = oXL.Workbooks.Open(excelFileName);
for (i = 1; i <= oWB.Sheets.Count; i++){
if (oWB.Sheets(i).name.lastIndexOf("月") != -1){
showSheet(i);
}
}
}
catch (e){
alert(e.message);
}
oWB.Close(); //不close工作簿的话，后果还是挺严重的。
oWB = null;
oXL = null;
}
function showSheet(sheetNO){
var oSheet = oWB.Sheets(sheetNO);
document.write("<table border=1>");
for (i = 1; i < oSheet.UsedRange.Rows.Count; i++){
document.write("<tr>");
for (j = 1; j < oSheet.UsedRange.Columns.Count; j++){
value = oSheet.Cells(i, j).Value;
if (value == undefined){
value = " ";
}
document.write(i == 1 ? "<th nowrap=true><b>" : "<td>");
document.write(value);
document.write(i == 1 ? "</b></th>" : "</td>");
}
document.write("</tr>");
}
document.write("</table>");
oSheet = null;
}
//-->
