I’m using regular expression email validation in Javascript.
I’m using the function listed below.
function validateEmail(email) {
var re = /^(([^<>()[\]\\.,;:\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 re.test(email);
}
It is suitable for a variety of email validation scenarios. Assume, for example,
validateEmail('m@s'); // return false
However, if I attempt to validate something like
validateEmail('m@com.com'); // return true
Which is correct according to the regular expression in this illustration.
What I need is for it to validate the text “com” before and after “.”, such that the two texts are not the same.
Any assistance would be much appreciated…
