laravel , How can I increment and decrement value with unique id

function incrementValue(e)
    {
        // use the quantity field's DOM position relative to the button that was clicked
        const qty = e.target.parentNode.parentNode.querySelector("input.req.amnt");
        var value = parseInt(qty.value, 10);
        value = isNaN(value) ? 0 : value;
        value++;
        qty.value = value;
    }


    function decrementValue(e)
    {
        const qty = e.target.parentNode.parentNode.querySelector("input.req.amnt");
        var value = parseInt(qty.value, 10);
        value = isNaN(value) ? 0 : value;

        value--;
        if(value == -1) {
            value = 0;
        }
        qty.value = value;
    }
