您好，我正在使用虚拟产品页面中工作，我需要这样做

所以我想这样做，我想有一个名为“Personal”的复选框，所以当单击“hide right way the company name Address”等时，我还想加税19%，当没有加税时，单击“add tax zero”

我已经使用了这个代码，我不知道如何为我的复选框获取值，所以当它为真时，我会加19%的税，并隐藏公司、地址、电话等名称，当它为假时，税为零

还有一个想法是，我如何获得选择国家，并检查是否在欧洲，以及我如何获得该值

编辑：如果可能，仅当国家i\'t不在欧洲时才添加复选框，

谁能帮我一下吗，谢谢

我附上一些图片以便更好地理解
