            $('.buy').bind('click', function() {
                var orderCode = $(this).attr("oc")
                alert(orderCode)
                $('.transit').hide();
                $('.FastPayment').show();
                $("#name").text(receiverName);
                $("#phone").text(receiverPhone);
                $("#addressDetail").text(addressDetail);
                $("#idCard").text(idCard);
                $("#orderCode").text(orderCode);
                
            });
        }
    });`请输入代码`

我现在的问题是在点击.buy的时候需要获取当前选中的属性,比如orderCode ,num之类的属性值,有什么方法可以获取到呢
