        });

        //Update data pegawai
    }else{
        alert("ERROR : Refresh halaman kembali !!");
    }

}

Fetch.php

<?php 

include"../../config/koneksi.php";

$nip = $_POST['nip'];

$sql = "SELECT * FROM tbl_branch JOIN tbl_employe ON tbl_branch.los_code = tbl_employe.los_code WHERE tbl_employe.nip = $nip";
$query = mysqli_query($koneksi,$sql);
$result = mysqli_fetch_assoc($query);

// close the database connection
    mysqli_close($koneksi);
    echo json_encode($result);

First thing to test - did the query work or fail? Add var_dump($result); after line 10 in fetch.php and run that script standalone, using a known good value for $nip. Before you go much further into this application, you may want to review the OWASP Guidelines for PHP and MySQL security. It looks like someone could feed something like "1 or 1=1" to the fetch.php script, and expose the entire table.
