可以读取EXCEL文件的js代码_javascript技巧

js读取 EXCEL 文件的实现代码，比较全了大家可以自行测试了。

首页给个有中文说明的例子，下面的例子很多大家可以多测试。

<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>

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

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;i8a850a13a7d4f6304fd432c6bbfe3440

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

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

document.write(value);
document.write(i == 1 ? "0d36329ec37a2cc24d42c7229b69747a01c3ce868d2b3d9bce8da5c1b7e41e5b" : "b90dd5946f0946207856a8a37f441edf");

}
document.write("f16b1740fad44fb09bfe928bcc527e08");
oSheet = null;
}
