php+jquery做onchange提交動作的問題，請人幫忙看看
我有個列表出來的結果，每列都有個onchange的動作，可是只有第一行的onchange可以操作，其他都沒有反應，不知道怎麼回事。

 include("../config.inc.php");

//醫生排班列表開始
$strDoctorTime = "";
if( isset($_REQUEST['Action']) && !empty($_REQUEST['Action']) && ($_REQUEST['Action'] == "setdoctortime") ){


$sqlDoctorTime = "select sid,doctorid,CONVERT(varchar(100), starttime, 20) as starttime,CONVERT(varchar(100), endtime, 120) as endtime,duration,createtime,type,operid,status,visits_counts,original_counts,istrue from gst_scheduling where doctorid = '".$_REQUEST['doctorid']."' ";
//if ( (isset($_REQUEST['starttime']) && !empty($_REQUEST['starttime'])) && (isset($_REQUEST['endtime']) && !empty($_REQUEST['endtime']))  ) {
//$sqlDoctorTime .= " ";
//}
$sqlDoctorTime .= " order by sid desc";

$resDoctorTime = $SqlDB->Query($sqlDoctorTime);

$arrDoctorTime = $SqlDB->getRows($resDoctorTime);


for($i=0; $i$strSelectStatus = ""; //初始號源下拉值
$strSelectStatus  = "";$strSelectStatus .= "if(trim($arrDoctorTime[$i]['original_counts']) == "1") $strSelectStatus .=  ' selected';$strSelectStatus .= ">1";$strSelectStatus .= "if(trim($arrDoctorTime[$i]['original_counts']) == "2") $strSelectStatus .=  ' selected';$strSelectStatus .= ">2";$strSelectStatus .= "if(trim($arrDoctorTime[$i]['original_counts']) == "3") $strSelectStatus .=  ' selected';$strSelectStatus .= ">3";$strSelectStatus .= "if(trim($arrDoctorTime[$i]['original_counts']) == "4") $strSelectStatus .=  ' selected';$strSelectStatus .= ">4";$strSelectStatus .= "if(trim($arrDoctorTime[$i]['original_counts']) == "5") $strSelectStatus .=  ' selected';$strSelectStatus .= ">5"; 
