  • 1 What do you mean by gmail? My email is [email protected] and it is a gmail account – lvil Commented Feb 13, 2012 at 7:23
  • Remember to allow the plus sign in the id. I hate it so much when websites tell me that the address I provided is invalid. – curial Commented Feb 13, 2012 at 10:13

Reset to default 4 
if (/@gmail\.$/.test(string)) {
    // This is a gmail id.
}

Use this regular expression

[a-zA-Z0-9]+\@gmail.

try this

if (/^([A-Za-z0-9_\-\.])+\@([gmail|GMAIL])+\.()$/.test(yourstring)) {
    // Valid  gmail id.
}

USE THE ASCII CODE FOR VALIDATION WITHOUT REGEX

<!DOCTYPE html>
<html>

    body{
