Question

Really got stuck on this simple regex. Need it to validate a string, that will be a mail without the “@domain.xxx”.

It must accomplish the following rules:

• there must be a string (only letters) starting.
• there must be a string (only letters) ending.
• this two strings must be separated by a dot.
• the complete string mustn’t contain any numbers or simbols.

I was trying with something like… /^[a-z]+$/^[.]+$/[a-z]+$/i …but no success.

Answer 1

/^[A-Za-z]+\.[A-Za-z]+$/

will work for ASCII letters.

If you also want to allow international letters (äá etc.) try

/^[^\W\d_]+\.[^\W\d_]+$/

[^\W\d_] means “Any character that not a non-alphanumeric character, not a number and not an underscore”.
