Parameter Value - Regular Expression

I want to restrict parameter value to accept date only, is below Regular Expression will work?

^([0-2][0-9]|(3)[0-1])(\/)(((0)[0-9])|((1)[0-2]))(\/)\d{4}$

  • Hi, at first glance I would say, yes that will work.

    Is there a problem?

    Do watch out for the fact you are using the "^" and "$" to mark the begin and end of the input string to search on. They are typically used combined with the multiline-flag (/m)

     

    By the way, I like to use regexr.com when building and testing regex.
