I have a regular expression which accepts only an email with the following pattern.
@stanford.edu.uk or word.edu.word
here it is
/(\.edu\.\w\w\w?)$/
It appears that this only works when .edu is followed by ".xx" (example: school.edu.au or college.edu.uk). I need this to also work for e-mails that end with .edu (example: school.edu or student.college.edu)
I tried this:
/(\.w+\.w+\.edu)$/
If any one can help?
Your (\.edu\.\w\w\w?)$ pattern requires a . and at 2 to 3 word chars after it before the end of the string, so it can't match strings with .edu at the end.
You may fix the pattern using
\.edu(?:\.\w{2,3})?$
See the regex demo
Details
\.edu - an .edu substring(?:\.\w{2,3})? - an optional non-capturing group matching 1 or 0 occurrences of
\. - a dot\w{2,3} - 2 to 3 word chars$ - end of string.Note that \w matches letters, digits and _. You might want to precise this bit in case you only want to match letters ([a-zA-Z] to only handle ASCII, or use ECMAScript 2018 powered \p{L} Unicode property class (not working in older browsers), or build your own pattern to support all Unicode letters).

\.edu(?:\.\w{2,3})?$
