计算Django Inline内的价格

我正在寻找一些方法来使用一些javascript从Django（动态）内联计算价格。

我有这个场景（在Django Admin中）： enter image description here

我正试图做那样的事情：

＆＃13;
＆＃13; 
{% block extrajs %}
    <script type="text/javascript">
        var subtotal = 0.00;
        $('.field-product_code select').change(function(){
            $('.related-widget-wrapper select').each(function(){
                product = $(this + 'option:selected').text();
                select_val = $(this).val();
                var regex = /[+-]?\d+(\.\d+)?/g;

                var str = product;
                var floats = str.match(regex).map(function(v) { return parseFloat(v); });
                var price = floats[0] * 1;
                console.log($(this).val());
            });
//            row_id = $(this).closest('tr').attr('id');
//            console.log($(row_id).find('.price_product'));
{#            if(row_id + ' .price_product'){#}
{#                console.log('existe ja');#}
{##}
{#            }else {#}
{#                //$(this).append("<div class='price'>aa"+ product +"</div>");#}
{#                var regex = /[+-]?\d+(\.\d+)?/g;#}
{##}
{#                var str = product;#}
{#                var floats = str.match(regex).map(function(v) { return parseFloat(v); });#}
{#                var price = floats[0] * 1;#}
{#                console.log(price);#}
{#            }#}


{#            subtotal += price;#}
{#            console.log(subtotal);#}
{#            $('#total').html(subtotal);#}
        })
    </script>
{% endblock %}

＆＃13;

也许我必须计算＆＃39;所有#id_movementcart_set-0-id，#id_movementcart_set-1-id，#id_movementcart_set-2-id和subsequents，但我该怎么做？
