<script type='text/javascript'>     //<![cdata[      $(document).ready(function() {       var currentitem = 7;             $('#addnew').click(function() {                 currentitem++;                 $('#items').val(currentitem);                 $('#items2').val(currentitem);                 var strtoadd = '<tr><td align="center"><input type="text" size="6" maxlength="6" id="ord_' + currentitem + '" maxlength="6" name="ord_' + currentitem + '" class="form-input-oth" onkeyup=$("#ordby_'+ currentitem +'").val($("#ordby_'+ currentitem +'").val())/></td>\n\                                     <td align="center"><input type="text" size="6" maxlength="6" id="srno' + currentitem + '" maxlength="6" name="srno_' + currentitem + '" class="form-input-oth" onkeyup="document.getelementbyid("srno_' + currentitem + '").value = this.value;"/></td>\n\                                     <td align="center"><textarea name="descrip_' + currentitem + '" id="descrip_' + currentitem + '" cols="70" class="form-input-textarea" onkeyup="document.getelementbyid("descrip_' + currentitem + '").value = this.value;"></textarea></td>\n\                                     <td align="center"><input type="text" size="6" maxlength="9" id="unit_' + currentitem + '" maxlength="6" name="unit_' + currentitem + '" class="form-input-rate" onkeyup="document.getelementbyid("unit_' + currentitem + '").value = this.value;"/></td>\n\                                     <td align="center"><input type="text" size="6" maxlength="9" id="rate_' + currentitem + '" maxlength="6" name="rate_' + currentitem + '" class="form-input-rate" onkeyup="document.getelementbyid("rate_' + currentitem + '").value = this.value;"/></td></tr>';                  var strtoadd3 = '<tr><td align="center"><input type="text" size="6" maxlength="6" id="ord_' + currentitem + '" maxlength="6" name="ord_' + currentitem + '" class="form-input-oth"  /></td>\n\                                     <td align="center"><input type="text" size="6" maxlength="6" id="srno_' + currentitem + '" maxlength="6" name="srno_' + currentitem + '" class="form-input-oth"  /></td>\n\                                     <td align="center"><textarea name="text_' + currentitem + '" id="descrip_' + currentitem + '" cols="70" style="display: none;"></textarea></td>\n\                                     <td align="center"><input type="text" size="6" maxlength="9" id="unit_' + currentitem + '" maxlength="6" name="unit_' + currentitem + '" class="form-input-rate"  /></td>\n\                                     <td align="center"><input type="text" size="6" maxlength="9" id="rate_' + currentitem + '" maxlength="6" name="rate_' + currentitem + '" class="form-input-rate"  /></td></tr>';                  $('#data').append(strtoadd);                 $('#data3').append(strtoadd3);              });         });      //]]>     </script>

you try remove this...

onkeyup=$("#ordby_'+ currentitem +'").val($("#ordby_'+ currentitem +'").val())

...and add event

$( '.class-name-for-input-element-you-want-to-attach-event-to' ).on( 'keyup', function() {     var itemidx = parseint( this.id.substr( 4 ), 10 ); // strips 'ord_' id     // whatever need integer      // find element in #data3 , replace value value in element triggered event     $( '#data3' ).find( 'selector' ).val( this.value ); });

in order work, you'll need add class name each of input elements.

simpler version
or if want copy input elements value #data3 tables corresponding input elements, use this: 

$( '#data' ).on( 'keyup', 'input, textarea', function() {     $( '#data3' ).find( '#' + this.id ).val( this.value ); });

notes
can attach events element exists in dom, can't directly attach event input or textarea element. instead can attach event #data that, assume, in dom.

without duplicated ids (ids removed #data3 table's input elements) 

$( '#data' ).on( 'keyup', 'input, textarea', function() {     $( '#data3' ).find( '[name="' + this.id + '"]' ).val( this.value ); });
