Validate Format Of An 8-character String Value

View 2 RepliesC# - Regular Expression To Validate Time Format
Jul 15, 2011I need to validate user input in some fields, where these are defining how to show time in some views.
Requirements: Time format must be expressed in Microsoft .NET way (check this MSDN Library article if you want to learn more about framework's date and time formatting: [URL]. Keep in mind I'm looking to validate the format instead of an actual time string.
For example, user may input:
HH:mm
hh:mm
ss
hh:ss
mm:ss
... and so on.
In fact, it should validate from the shortest to longest time format available. Another point is I need to do it in client-side using JavaScript. In other words, any given regular expression by you should work in browsers JavaScript regular expressions' engine. I can't use ASP.NET validation engine, or any other. Because of project's requirements, I need to avoid that.
