missing leading zero id from db using ajax

missing leading zero id from db using ajax

inside mysql db which is table employe in coloumn id_employee, some data have a leading zero, etc :
id_employee : 0378192919
empy_name : Jack

i need to get id_employee for delete employe in my aplication, then i using ajax method like this :

  1. if(id) {
  2.       alert(id);
  3.       $("#deleteBtn").unbind('click').bind('click',function(){
  4.          $.ajax({
  5.             url: 'pegawai/delpeg.php',
  6.             type:'post',
  7.             data: {emp_id : id},
  8.             datatype: 'json',
  9.             success:function(response) {
return value is  378192919 , the first number  0  not showing in alert box. why ? then how to get entire value id_employe from db ?



as u can see the picture above , when i retrive data, id_employee is show entirely , i cant delete this employee because she had id_employee with leading zero. its mean there is no data  378192919  in db , it should be  0378192919 , below is code for button delete carry data id_employee from looping result.

  1. <a type="button" data-toggle="modal" data-target="#editEmployModal" onclick="editEmploy('.$row['nip'].')">
  2.     <span class="glyphicon glyphicon-edit"></span> Edit</a>
and below is js code for catch id_employee from php

function delEmploy(id = null) {

  1.     if(id) {
  2.       
  3.       alert(id);
  4.       $("#deleteBtn").unbind('click').bind('click',function(){
  5.          $.ajax({
  6.             url: 'pegawai/delpeg.php',
  7.             type:'post',
  8.             data: {nip :id},
  9.             datatype: 'json',
  10.             success:function(response) {
  11.                 if(response.success == true) {

the delete employe cant run because ajax function return id_employee without leading zero ..
