Validate email address using javascript

Question

here's the code that I'm using to validate email address on clicking submit button by the user,

/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(EmailID);

I would like to allow apostrophe(') to the email address entered by the user, what would be the modification for the regex above?

See ex-parrot.com/~pdw/Mail-RFC822-Address.html Anything less than that is imperfection. In other words, it's very hard to validate all variations of valid email addresses. — Rick Viscomi

The best way to validate an e-mail address is to try it. As long as it has an @ symbol it could be an e-mail address. — nullability

There is certainly a HUGE gap between the regex offered here and the one Rick Visconni recommends. Your regex is broken in several regards Keethan. — symcbean

I recommend using Validator - github.com/chriso/validator.js, email address syntax is impossibly complicated and this library accounts for that. — Matthew Rathbone

try this:

/^(\w|')+([\.-]?(\w|')+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/

it will allow apostrophe anywhere before the '@'

Your current Regex match the following email address :

But doesn't match this :

[email protected]

If you're just basically trying to validate an email adress containing one apostrophe like this one :

test'[email protected]

Then just add a quoi in the first bracket :

/^\w+(['.-]?\w+)@\w+([.-]?\w+)(.\w{2,3})+$/

But it still won't match A LOT of email addresses (one with a dash and an apostrophe, one with multiples dash [...]).

Why do you think 'that [email protected]' wont match? if you try the regex, you'll see it will. the ([\.-]?\w+) capture group has a star, so it could be repeated as many times as need be. it won't match this however: '[email protected]'

@hhamilton He actually edited the Regex, it was something else at first

Using Regular Expressions is probably the best way. Here's an example (demo):

function validateEmailAddress(emailID) { 
    var emailRgx = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\
".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA
-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
    return emailRgx .test(emailID);
}
