如何从表JSon获取ID？

Question

This is my code table json :

<?php
    header('content-type:application/json');
    include '../koneksi.php';
    $select = mysql_query('select tb_menu.*, tb_stock.jumlah_stok from tb_menu INNER JOIN tb_stock
                    ON tb_menu.kategori_stok=tb_stock.kategori_stok');
    $row=array();
    while($row=mysql_fetch_array($select))  
    {
        $arrayx=array(  "nama_menu"=>$row['nama_menu'],
                    "jenis_menu"=>$row['jenis_menu'],
                    "harga"=>$row['harga_menu'],
                    "disc"=>$row['disc'],
                    "deskripsi"=>$row['detail_menu'],
                    "gambar"=>"<img class='img-rounded' src='images/$row[gambar_menu]' alt='gbr' width='120'>",
                    "jumlah_stok"=>$row['jumlah_stok'],
                    "input_jml"=>"<input type='number' min='1' max='50' class='form-control' id='input_jml' name='input_jml' />",
                    "ket"=>"<textarea class='form-control' id='ket' name='ket' placeholder='Keterangan ...'></textarea>"
        );
        $rows[] = $arrayx;
    }
    echo json_encode($rows);
?>

html code :

                if (index % 2 === 0 && index / 2 < classes.length) {
