我在Python Flask中创建了一个WTform，其中有一个交付表单。如果客户的帐单邮寄地址与送货地址不同，那么我将启用div，其中包含帐单邮寄地址的字段。我正在通过jquery隐藏和显示div。 我本来所有的领域中一个Flaskform，但转念一想，如果我把单独的FlaskForm计费领域，手柄form.validate_on_submit（）分别为第2形式，然后可能是我可以跳过验证在开票DIV领域。 但是不，它仍在这些字段上执行验证，因此，我无法继续前进。如果用户具有相同的地址，则帐单字段将为空且无法通过验证。 我确定人们一定遇到过这种情况，但是我找不到任何答案。 有人可以指导我吗？
我正在附上代码，以解释自己。
