推荐答案

如果您只需要验证日期的格式，则使用正则表达式.

如果您需要针对特定​​日期进行验证，则最好使用自定义验证程序，因为输入的日期可以采用不同的格式，例如一个或两位数的月份.

If you just need to validate the format of the date then use a Regular Expression.

If you need to validate against a specific date then using a custom validator would be better since the date entered could be in different format, such as one or two digit month.
