Passing data-id1 and data-id2 values to a modal in PHP using AJAX and JavaScript

I want to pass double id (data-id1 and data-id2) values in modal.
when i try to do so i get only on data-id1 being pass the data-id2 doesn't get pass,
so the Modal popups with an empty table.

this is my view before triggering the modal

this is my HTML query:

<a class="openModal" data-id1="<?php echo htmlentities($result->requestitem_item); ?>" data-id2="<?php echo htmlentities($result->request_NUMBER); ?>" data-toggle="modal" href="#myModal"><input style="font-size:25px" type="text" name="itemserialno[]" value="" required>

and this is my script:

<script>
  $('.openModal').click(function(){
      var id1 = $(this).attr('data-id1');
      var id2 = $(this).attr('data-id2');
      $.ajax({url:"modalajax.php?id1=&id2="+(id1&id2),cache:false,success:function(result){
          $(".modal-content").html(result);
      }});
  });
</script>

<div id="myModal" class="modal fade" role="dialog">
  <div class="modal-dialog" style="width:50%">
    <div class="modal-content">

    </div>
  </div>
</div>

Below is my Modal $_GET trigger:

$ID=$_GET['id1']??'';
$ID1=$_GET['id2']??'';

$sql = "SELECT * from  itemTABLE where (itemTABLE_item ='$ID1' and itemTABLE_requestNUMBER ='$ID2') and itemTABLE_acceptance != 'Reject' " ;

It should be like this

$.ajax({
    url: "modalajax.php?id1=" + id1 + "&id2=" + id2,
    cache: false,
    success: function(result) {
        $(".modal-content").html(result);
    }
});
