Field validation: Regular Expressions : Stop Invalid Characters

[Aditya Banka2]

Hello All,

I have a requirement where I need to validate a field in service catalog. It shouldn't allow special characters as '`~!@#$%^&*()|+=?;:'",<>{} []\/

Also it shouldn't allow

\W = Anything that isn't a word character (including punctuation etc)

\s = Anything that is a space character (including space, tab characters etc)

also it shouldn't allow the domain @xx.com

I tried creating a new variable validation regex with regular expression as [a-zA-Z0-9]{1,20} and using it under Validation Regex.

With this it is not allowing any special characters as such, but how can I incorporate \W \s and domain @xx.com, in the same regular expression.

You can use below regex:

^([a-zA-Z0-9_\-\.]+)@domain\.com$
