if stupid way of doing please show me right path!

<td>           <div class="form-group">     {{ form::text('report_mon_time', input::old('report_mon_time'), array('name' => 'time', 'class' => 'form-control-s', 'onblur' => 'findtotaltime()')) }}   </div> </td> <td>   <div class="form-group">     {{ form::text('report_tue_time', input::old('report_tue_time'), array('name' => 'time', 'class' => 'form-control-s', 'onblur' => 'findtotaltime()')) }}   </div> </td>   <div class="form-group">     {{ form::text('report_tot_time', input::old('report_tot_time'), array('id' => 'tot_time','class' => 'form-control-s')) }} </div>  <script> function findtotaltime(){     var number = document.getelementsbyname('time');     var arr = number;     var tot=0;      for(var i=0;i<arr.length;i++){         if(parseint(arr[i].value))             tot += parseint(arr[i].value);     }     document.getelementbyid('tot_time').value = tot; } </script> 

change

for(var i=0;i<arr.length;i++){ for(var i=0;i<arr.length;i++){     if(parseint(arr[i].value))         tot += parseint(arr[i].value); } 

to

 for(var i=0;i<number.length;i++){     if(parseint(number[i].value))         tot += parseint(number[i].value); }
