Use RegExp to restrict spaces

[microkarl]

Hi all,

 

I want to enhance this regular expression - ^[0-9a-zA-Z]{6,20}$ to not allow any spaces (leading, in between, and trailing). I know the regexp for space is (\s*), but just don't know how to put them together. Can any one help?

 

Regards,

Kyle

I put it after the 9 and it seems to work

^[A-Za-z0-9\s]{6,20}$

Iceplug, thanks for your respond. It doesn't work. It works like this:

- "Test1" - no match (expected)

- "Test1 " - no match (expected)

- "Test123" - match (expected)

- "Test123 " - match (not expected)

 

Basically, if I have string is less than 6 characters, regardless the spaces, it should fail. But as long as the string is with 6-20 chars. the regex allows spaces. which is not allowed. Can you help?

 

Thanks.
