<script language=javascript>    



function replace(v)



{



//容错问题，请读者自行进行判断。



//定义SQL语句



var sql = "select * from Dictionary where MainID='" + v + "'" ;



//新建数据库连接对象和数据集存取对象



var ConnDB = new ActiveXObject("adodb.connection");



var rs = new ActiveXObject("ADODB.Recordset");



//这里填入要连接的DSN



ConnDB.ConnectionString="DSN=***;uid=***;pwd=***";



ConnDB.open



rs.open(sql,ConnDB,1,1);



if (rs.RecordCount>0){



if (v==parseInt(rs("MainID"))){



//字符串连接



document.all('txt').value = v + rs("MainValue");



var sql=null;



rs.close



ConnDB.close



return;



} else {



var sql=null;



alert("没有此代号！");



txt.select();



txt.focus();



rs.close



ConnDB.close



}



}



</script>



<input type=text id=txt name=txt onblur="replace(this.value)">
