Jquery Area [Works fine] :

Action Part one :

<script>
    function popfield(acyr,crs,cls) {          
      $.ajax({  
         type : "POST",
         url  : "mattendance.php",
         cache: false,
   data : "academic="+ acyr +"&course="+ crs +"&class="+ cls,                                                   success: function(data) {                 
          $(".sId").html(data).show();                
         }             
     });            
        }   

$("#aone").ready(function() {     


    $("#academic").change(function () {
        var acval = $(this).find("option:selected").text();             
    });

    $("input:radio[name=course]").click(function() {
        var csval = $('input[name=course]:checked', '#aone').val();             
    });     

    $("#first").click(function () {
        if ($("#first").is(":checked")) {
            var sclass = $('input[name=first]:checked').val();                  
            $(":checkbox").click(popfield($("#academic").find("option:selected").text(),$('input[name=course]:checked', '#aone').val(),$('input[name=first]:checked').val()));                                        开发者_Go百科              
        }                                   
    });

    $("#second").click(function () {
        if ($("#second").is(":checked")) {
            var sclass = $('input[name=second]:checked').val();                                     
            $(":checkbox").click(popfield($("#academic").find("option:selected").text(),$('input[name=course]:checked', '#aone').val(),$('input[name=second]:checked').val()));                             
        }                                   
    });

    $("#third").click(function () {
        if ($("#third").is(":checked")) {
            var sclass = $('input[name=third]:checked').val();                                      
            $(":checkbox").click(popfield($("#academic").find("option:selected").text(),$('input[name=course]:checked', '#aone').val(),$('input[name=third]:checked').val()));                      
        }                                   
    }); 

});

Action Part two [Problem is here] :

function callone(sid) {

    alert('alert one :'+ sid);

    var dataString = "Id="+ sid ;

       $.ajax({         
     type : "POST",
     url  : "mattendance.php",
     data : dataString,             
    success: function(data) {                 
      $("#nameone").html(data);               
     }             
       }); 
   }                            }

[PHP part for Action Two :]

<?

// Call to Names from Ajax 
 if($_POST["Id"]!="")
  {        
   $dbselect=mysql_query("SELECT * FROM `tblNewStudent` WHERE `IdNo`='".$_POST["Id"]."' ORDER BY `SNo` ASC ");         
   $row = mysql_fetch_object($dbselect);
    print $row->Name;                 
   }

?>

I tried alot by seeing examples but cant able to display new value in text field n got wierd , seriously looking forward to ur best answers..
