in js.

$(".printbill").click(function () {             $.ajax({             url: "admin_search_save.php",             data: {                 id:$(this).val(),                 studentid:$(".studentid").val(),                 ssize:$(".ssize").val(),             },             success: function (data) {             }         });     });

you need use event delegation dynamically added content. 

$(document).on('click','.printbill',function () {          // capture input , select value traversing parent(tr),         // find element [input, select]         // traversing method depend on table structure         var studid    = $(this).closest('tr').find('input[name=studentid]').val(),             ssizedata = $(this).closest('tr').find('select[name=ssize]').val();          $.ajax({         url: "admin_search_save.php",         data: {             id        : $(this).val(),             studentid : studid,             ssize     : ssizedata,         },         success: function (data) {         }     });   });
