日期格式为“dd / MM / yyyy”验证 [英] date in format "dd/MM/yyyy" validation
问题描述
我在asp.net中编程。我在TextBox中有一个日期格式为dd / MM / yyyy。
我想验证日期是否真的正确。
我使用RegularExpressionValidator
ValidationExpression =" [0-3] [0-9] / [0-1] [0-9] / [1-2] [0-9] [0- 9] [0-9]"，但是用户
可以写日期31/02/2000验证员说它是正确的（每个人都知道，2月有28天或29天）。
我在考虑使用RangeValidator和Type ="日期" ;.但是如何告诉
RangeValidator，该日期格式为dd / MM / yyyy。 ？
也许这是更简单的解决方案？
我想在客户端站点拥有完全安全的验证方法..
感谢您的帮助

我想验证日期是否真的正确。
首先，您的日期格式不明确。例如。以这种格式，明天的日期
将显示为12/11/2008。有些人会在11月12日看到，但是其他人（例如我们在美国的朋友）会将其视为2008年12月11日。你应该看到
总是用三个显示日期 - 数字月。
也许这是更容易的解决方案？
我想在客户端网站上有完整的安全验证方法..
到目前为止最简单的解决方案，以及永远不会允许无效日期的解决方案，
不允许用户手动输入日期。相反，使用日期
选择器。
有几十个，也许几百个可用：

Hi,
I program in asp.net. I have a date in TextBox in format "dd/MM/yyyy".
I would like to validate if the date is realy correct.
I used RegularExpressionValidator with
ValidationExpression="[0-3][0-9]/[0-1][0-9]/[1-2][0-9][0-9][0-9]", but user
can write date "31/02/2000" and validator says that it is correct (everybody
know that Febuary has 28 or 29 days).
I was thinking of using RangeValidator with Type="Date". But how to told
RangeValidator, that date is in format "dd/MM/yyyy" ?
Maybe it is easier solution ?
I would like to have total secure validation method in client site..
Thanks for help

I would like to validate if the date is really correct.Firstly, your date format is ambiguous. E.g. in that format, tomorrow''s date
would appear as 12/11/2008. Some people will see that as 12 November but
others (e.g. our friends in US) will see it as 11 December 2008. You should
always display dates using a three-digit month.
Maybe it is easier solution ?
I would like to have total secure validation method in client site..By far the easiest solution, and one which will never permit invalid dates,
is not to allow users to enter dates manually at all. Instead, use a date
picker.
There are dozens, maybe hundreds, of these available:
