อยากทราบวิธีทำให้ scrollbar ไม่เลื่อนขึ้นไปอยู่บนสุด เมื่อกดปุ่ม submit ค่ะ

window.scrollBy(100,100);

if($_POST["hdnCmd"] == "Update")
{
	$strSQL = "UPDATE customer SET ";
	$strSQL .="date = '".$_POST["txtEditdate"]."' ";
	$strSQL .=",id_brand = '".$_POST["txtEditbrand"]."' ";
	$strSQL .=",id_no = '".$_POST["txtEditno"]."' ";
	$strSQL .=",total = '".$_POST["txtEdittotal"]."' ";
	$strSQL .=",area = '".$_POST["txtEditarea"]."' ";
           $strSQL .=",status = '".$_POST["txtEditstatus1"]."' ";
	$strSQL .=",detail = '".$_POST["txtEditdetail"]."' ";
	$strSQL .="WHERE  id = '".$_POST["hdnEditid"]."' ";
	$objQuery = mysql_query($strSQL);
	if(!$objQuery)
	{
		echo "Error Update [".mysql_error()."]";
		} else {
		echo "<script language=\"JavaScript\">"; 
echo "<meta http-equiv='refresh' content='2;url=$_SERVER[PHP_SELF]?id={$_POST['hdnEditid']}'>";

echo "</script>";
	}
	}
