Don't want to close modal after submitting data in modal PHP

Question

I want to keep the same pattern after submitting this form

generateBarcode.php:

<form action="savegenarateBarcode.php?id=<?php echo $d1; ?>" method="post"> ;

savegenerateBarcode.php:

<?php
try {
    session_start();
    include('../connect.php');

    $d1 = $_GET['id'];
    $b = $_POST['serialnumber'];
    $sqlm = "select *from product_item where serialnumber='".$b."'";

    $query = $db->prepare($sqlm);
    $user_array = $query ->execute();
}

How can I keep generateBarcode.php(modal) unchanged after submitting this form?

I think you should use ajax because the form submit method reload the page.

var id = '<?php echo $d1; ?>';
$("#submit").click(function(){
        $.ajax({
            type: 'GET',
            url: "savegenarateBarcode.php",
            data:`id=${id}`
            success:function(data){
             alert(data);
            }
        });
    return false;
    });
