Solution 1

hi
Just put one @ before '@'

like this
var re = /^[a-zA-Z0-9]([\w\-\.\+\']*)@@([\w\-\.]*)(\.[a-zA-Z]{2,20}(\.[a-zA-Z]{2}){0,2})$/;

hope this will work!!

thanks

Solution 2

You can try it in this way

 <script type="text/javascript">
function validateEmail(email)
{
 var reg = /^\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$/;
 if (reg.test(email)){
 return true; }
 else{
 return false;
 }
} 
</script>
