How to pass arResult in ajax.php of a component?

Question

1C-Bitrix

I need to pass the element ID from the same component to the ajax.php script. The arResult array is empty. The option with sessions is not suitable, because if the user opens 2 tabs with different elements, then the ID of the last opened tab will be written to ajax.php.

What other options are there?

You can pass the element ID in AJAX:

$(document).ready(function() {
        $('#one_click_buy').submit(function(e) {
            e.preventDefault();
            $.ajax({
                type: "POST",
                url: 'component_folder/ajax.php',
                dataType: "json",
                data: {'id': <?= $arResult['PRODUCT_ID'] ?>},
                success: function(response)
                {
                    $('#OneBuyClickRX').modal('hide');
                    $('#ordersuccess').modal('show');
                }
            });
        });
    });

And then catch in ajax.php
json_decode($id);
