Angular Internet Routable Email Address Validation

I have a form which I need to verify internet routable email addresses before submission and deny local routing. Both ng-pattern='email.text' and ng-pattern='email'pass bob@bob whi

Solution 1:

Wiktor's reg ex in the requested format, passes internet routable email addresses and denies local routing:

ng-pattern="/^(?:[a-z0-9!#$%&\x27*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&\x27*+/=?^_`{|}~-]+)*|\x22(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])*\x22)@(?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?|\[(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?|[a-z0-9-]*[a-z0-9]:(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])+)\])$/"
