页面数据计算

• 在tt_order/list.html中编写js

{% block script %}
    <script>
    $(function () {
        var total=0,count=0;
        $('.goods_list_td').each(function () {
            var price=parseFloat($(this).children('.col05').children('span').text());
            var count1=parseInt($(this).children('.col06').text());
            var total1=price*count1;
            total+=total1;
            count+=count1;
            $(this).children('.col07').text(total1.toFixed(2)+'元');
        });
        $('.total_goods_count').children('em').text(count).end().children('b').text(total.toFixed(2)+'元');
        $('.total_pay b').text((total+10).toFixed(2)+'元');
    });
    </script>
{% endblock script %}
