RegEx to allow at least one dot and all character

Question

How do I validate the following emails with a regular expression?

[email protected]
[email protected]
[email protected]

/^([a-zA-Z0-9.]+)$/

I have tried using pattern /^([a-zA-Z0-9.]+)$/ .But it is not working — B Nagarjuna, Jun 06 '19 at 07:05

I'm guessing that here we wish to validate these emails, for which we can use an expression similar to:

^([a-z0-9]+((?=\..+@.+\..+)[a-z0-9.]*@[a-z0-9]*\.[a-z0-9]*))$

with an i flag and we can allow more chars, if we like so.
