I have some code which includes the following:
pattern="[a-z0-9._%±]+@[a-z0-9.-]+.[a-z]{2,4}$"
Could some kind person step through this and explain to me what each part of this code actually does? Thank you
That is basically verifying that it is an email address.
Its saying at least one A-Z or 0-9 or . or _ etc
then the @ symbol
then a domain name at least one character
then the dot
then A-Z two to four times…
