使用JavaScript选择复选框时隐藏表单元素

Question

我有付款表格，当有人选择'paypal'选项时，我希望它具有信用卡详细信息。我已经从一个现有的代码中获取了一些代码，该函数可以为我的编辑表格进行调整 - 但我似乎无法使其工作...

如果有人可以指出我出错的地方，它将非常感谢！（我仍然是脚本的新手）

我需要帮助的脚本是表格的底部。

我需要做什么：

当您单击" paypal"复选框并关闭" hidecc"等级的所有行以打开和关闭。

。

，因为您包括jQuery，为什么不尝试此操作：

$(document).ready(function() {
                $('[name="PaymentMethodType"]').change(function () {                        
                    if ($(this).val() == 1) {
                        $('.hideCC').show();
                    } else {
                        $('.hideCC').hide();
                    }
                });
            });
