javascript - Validation for xxx-xxx-xxxx or (xxx)xxx-xxxx

Whats the regex for

xxx-xxx-xxxx
or
(xxx)xxx-xxxx

I can create regex for the first one with

/^\d{3}-\d{3}-\d{4}$/

but how to add rule in this so it can also handle the second one?

Answer

You can use this: -

/^(?:\(\d{3}\)|\d{3}-)\d{3}-\d{4}$/
