Email validatior Javascript

Question

Here is my javascript code

 $scope.isValidEmailAddress = function(emailAddress) {
            // var pattern = new RegExp(/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/);
            var pattern = new RegExp(/^[\w\-\.\+]+\@[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,4}$/);
            return pattern.test(emailAddress);
        };

When i validate below email it will return true but this is not, I need to validate this type of email

rohan@yahoo.co.in.in

It should be invalid email

Please explain what it is which makes the address invalid. I get the impression that you mean the doubled top-level domain, but I am not sure. Providing more sample input with desired result might be helpful. — Yunnosch, Jun 20 '17 at 05:34

Updated as per comment.

If you want to make it possible to add up to two top level domain names you can make the second domain optional.

$scope.isValidEmailAddress = function(emailAddress) {
    // Same regex as before but an additional TLD regex has been added.
    var pattern = new RegExp(/^[\w\-\.\+]+\@[a-zA-Z0-9\-]+\.([a-zA-z0-9]{2,4}\.)?[a-zA-z0-9]{2,4}$/);
    return pattern.test(emailAddress);
};

But in case email address is like this : **rohan@yahoo.co.in** it is giving false value. – shiva Jun 20 '17 at 05:21
Do you only want to allow a maximum of two dot characters after the @ symbol? – Mike Jun 20 '17 at 05:23
@shiva There was a typo. My mistake. – Mike Jun 20 '17 at 20:33
