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