Hi
I have to allow user to enter only 3 special characters in the email address and restrict them from entering any other special characters.
Below are the special characters
- hyphen
_ underscore
' apostrophe
The regular expression I am using is "\w+[-+.'_]*(\w+)*[\w]@\w+([-.]\w+)*\.\w+([-.]\w+)*"
However this is failing when user is entering an email in the format
test-test'
[email protected].
I think the combination of - and ' is not being allowed in the above expression.
Please help to resolve the issue.
Thanks.
