有些时候我们的站点提供给客户数据导入导出功能，通常选择媒介格式为xls，下面是用JavaScript完成对客户端xls数据的载入：
<html>
<head>
<title>Untitled</title>
<script>
function importXLS(fileName)
{
objCon = new ActiveXObject("ADODB.Connection");
objCon.Provider = "Microsoft.Jet.OLEDB.4.0";
objCon.ConnectionString = "Data Source=" + fileName + ";Extended Properties=Excel 8.0;";
objCon.CursorLocation = 1;
objCon.Open;
var strQuery;
//Get the SheetName
var strSheetName = "Sheet1$";
var rsTemp = new ActiveXObject("ADODB.Recordset");
rsTemp = objCon.OpenSchema(20);
if(!rsTemp.EOF)
strSheetName = rsTemp.Fields("Table_Name").Value;
rsTemp = null
rsExcel = new ActiveXObject("ADODB.Recordset");
strQuery = "SELECT * FROM [" + strSheetName + "]";
rsExcel.ActiveConnection = objCon;
rsExcel.Open(strQuery);
while(!rsExcel.EOF)
{
for(i = 0;i<rsExcel.Fields.Count;++i)
{
alert(rsExcel.Fields(i).value);
}
rsExcel.MoveNext;
}
// Close the connection and dispose the file
objCon.Close;
objCon =null;
rsExcel = null;
}
</script>
</head>
<body>
<input type=file id=f>
<input type=button id=b value="import" onclick="if(f.value=='')alert('请选择xls文件');else importXLS(f.value)">
</body>
</html>
