regex - Javascript multiple email regexp validation

Question

Normally validation of simple email is:

/^([A-Za-z0-9_-.])+@([A-Za-z0-9_-.])+.([A-Za-z]{2,4})$/

This will validate email like [email protected]

But how to validate if email is multiple?

entry 1: [email protected], [email protected], [email protected]
entry 2: [email protected] , [email protected] , [email protected]
entry 3: [email protected], [email protected] , [email protected]
entry 4: [email protected]

This emails is a possible entries that user will input. Also expect thier is 2 or 3 or 4 or more emails sometimes.

Thanks for the answers.

Answer 1

Split the emails on a comma and validate the entries

var x = getEmails();
var emails = x.split(",");
emails.forEach(function (email) {
  validate(email.trim());
});

Where getEmails() gets the emails from the page, and validate runs your regex against the emails
