How to pass value to modal window?

Question

1C-Bitrix

Hello. I have a catalog.section component and a button to cart. I need that when this button is clicked, a modal window opens and parameters are passed there - for a start, at least the name of the product.
How can I do it?
I understand that the onclick event should be hung on this button

<div id="nameofproduct">Здесь имя товара</div>
<button onclick="openwindow('<?=$arItem["NAME"]?>')">В корзину</button>
<script>
function(openwindow){
//что тут писать
}
</script>

Answer 1

$( document ).ready(function() {

        $('button.class').click(function(){
            $(div.class).text($('#nameofproduct'));
        });

    });

something like that... use libraries, you don't have to use on-click... if you had brought the layout of the modal window, it could have been more precise...
Actually, such features are made in Ajax. Perhaps you have another task,
