Last month I wrote about regular expressions in Java, today I’ll show you how to use regular expression in JavaScript to validate email address.
Here is the code to validate email address in JavaScript using regular expression.
function validateEmail(elementValue){
var emailPattern = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/;
return emailPattern.test(elementValue);
}
Explanation:
The argument to this method is the email address you want to validate.
In the method body we define a variable (’emailPattern’) and assign a regular expression to it.
/^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/
To understand the regular expression we will divide it into smaller components:
/^[a-zA-Z0-9._-]+: Means that the email address must begin with alpha-numeric characters (both lowercase and uppercase characters are allowed). It may have periods,underscores and hyphens.
@: There must be a ‘@’ symbol after initial characters.
[a-zA-Z0-9.-]+: After the ‘@’ sign there must be some alpha-numeric characters. It can also contain period (‘.’) and and hyphens(‘-‘).
\.: After the second group of characters there must be a period (‘.’). This is to separate domain and subdomain names.
[a-zA-Z]{2,4}$/: Finally, the email address must end with two to four alphabets. Having a-z and A-Z means that both lowercase and uppercase letters are allowed.
{2,4} indicates the minimum and maximum number of characters. This will allow domain names with 2, 3 and 4 characters e.g.; us, tx, org, com, net, wxyz).
On the final line we call test method for our regular expression and pass the email address as input. If the input email address satisfies our regular expression, ‘test’ will return true otherwise it will return false. We return this value to the calling method.
You can call this method whenever you want to validate email address.
Hey, nice useful piece of code. Always nice to find something that takes a fairly common task, such as email validation, and breaks down the logic and provides a simple piece of code in the end.
hey, nice explanation, its helped me allott.

Hi can anyone help me how to invalidate the session , when i am clicking LOGOUT button. I use session.invalidate() method , the page has been expired. But when click back button on browser it goes to back page. How to avoid this. I request you any body can solve this problem.

Hi,
Very nice one which helped me a lot.
I tried the below code for checking alphabets, hyphen and underscore. However its not working.
Could any of you help me on this.
function validateChars(elementValue)
{
var charsPattern = /[a-zA-Z0-9_-]*/;
return charsPattern.test(elementValue);
}
Thanks.
Thanks for this. Saved me some work.
There is a small error in the regexp: top-level domains could be longer than 4 characters (like .travel and .museum).

Don’t you need to escape the period? ie:
[a-zA-Z0-9._-]
should be:
[a-zA-Z0-9._-]
Otherwise, isn’t a period a single character wildcard?
And can’t a-zA-Z0-9 be replaced with \w?
ps Should also add apostrophe ‘ for Irish names, that’s the reason I was hunting this stuff down!
Hi,
Thank you very much for this article. It helps me for achieving my form. In addition, your explanation is clear and light.
Good Job – really easy to understand explanation
Hey Mike,
[a-zA-Z0-9_] can be replaced with w.
also, because the . is included in the second character class(after @), this would be considered a valid email:
a@a…….com
not sure what the solution to that is. .
.{1} does limit the repetition of . to one, but since the previous characters have already been passed, the limiter becomes irrelevant.
anyone?
Hi Zaheer,
Really clever solution, using regular expressions for validations.
I am studing at uni and we covered regular expressions on our
Unix system programing course. I see the usefulness of regular expressions now !
Keep posting more tips 😉
Cheers,
Armando
.@..ww
is a valid email address?
thanks
Not that I’m totally impressed, but this is more than I expected for when I found a link on SU telling that the info here is quite decent. Thanks.
Validate email address using regular expressions, nice piece of work. Very simple and clean. Thanks for the code. Helps me a lot.

This pattern isn’t a good for e-mail addresses. This pattern will filter out few of the WELL-FORMED e-mails and of MAL-FORMED as well.
gonzo: that is quite an unfounded statement. could you please give examples of both. and if you are so smart, could you show solutions also? (there is already a comment showing it accepts faulty emails)
I too found that this regex has some flaws. An email like asdf@asdf would pass the filter. It doesn’t check for the .tld.
The guys at http://www.4guysfromrolla.com/webtech/052899-1.shtml have offered this, which ensures there’s a .tld :
^[\w-_.+]*[\w-_.]@([\w]+\.)+[\w]+[\w]$
I would encourage everyone to learn RegEx, it’s invaluable when you have to manipulate data, and who doesn’t these days. Zaheer’s lesson still teaches a lot.
@Mike VandeVelde
I believe apostrophes are illegal characters in emails.
based on the above I think that:
/^[w.+-]+@[w.-]+.[a-z]{2,6}$/i
might be a better solution.
w to match alphanumeric characters and underscores
i on the end to be case insensitive
{2,6} rather than {2,4} to cope with .museum
this still doesn’t address .@..ww or similar though.
/^((w++*-*)+.?)+@((w++*-*)+.?)*[w-]+.[a-z]{2,6}$/i
Should deal with that problem though (I have not tested this fully but it works on those that I have tested which it should work on and catches those that are invalid which I tried)
(w++*-*) matches an more than one alphanumeric followed by zero or more +s and zero or more -s
(w++*-*)+ matches this happening at least once.
((w++*-*)+.?)+ matches this happening at least once with or without a . afterwards
((w++*-*)+.?)* is the same except that it matches 0 or more times.
[w-]+ matches at least 1 alphanumeric character or hyphen.
I hope this helps people.
Daniel wrote:
/^((w++*-*)+.?)+@((w++*-*)+.?)*[w-]+.[a-z]{2,6}$/i
Nice one!
I tested it with something like:
x test
x test..@..com
x test..@example..com
x test..@example.example.com
x test.2@example.com.
v test.2@example.example.com
(x fails, v passes)
I used to have a script of my own that worked really nice (apart from 6-char TLD), but was about 45 lines of code…
Zaheer and Daniel: Thank you for this huge improvement 😉
In the above test.@test.com is pass, also numerics / _ are allowed to start the email address, below regex works fine to some extent.
/^[a-zA-Z]([a-zA-Z0-9-_])*(.[a-zA-Z0-9-_])*@[a-zA-Z0-9](([a-zA-Z0-9-_.])*)+.[a-zA-Z]{2,4}$/
Thanks and congratulations to Zaheer for this article: It is very well written and it is easy to read. Thanks also to the rest of people who contributed to enhance this code.
I would like to share with you the following regex that I tried with all samples shown before (and some more, of course). I think it is worth a try:
^([A-Za-z0-9]{1,}([-_.&’][A-Za-z0-9]{1,}){0,}){1,}@(([A-Za-z0-9]{1,}[-]{0,1}).){1,}[A-Za-z]{2,6}$
I think this pretty well matches a great number of e-mail addresses.

Francisco.
Hai Latha,
I know its a very late reply for the question which you’ve asked. Anyway let it help the users who view this forum.
Your Question:
“Hi can anyone help me how to invalidate the session , when i am clicking LOGOUT button. I use session.invalidate() method , the page has been expired. But when click back button on browser it goes to back page. How to avoid this. I request you any body can solve this problem.”
Answer:
response.setHeader(“Cache-Control”,”no-cache,no-store”);
response.setDateHeader(“Expires”, 0);
response.setHeader(“Pragma”,”no-cache”);
just try to add the above code and check.
That helped me a lot!!
THANK YOU!!
good one..!
Are mail-adresses with more than one “@” okay?
I was just wondering. Many of the regexp allow more than one “@”. Nevertheless some regexp allow combinations like test@test@example.org ….
All exp failing at test:
test@example..org
Any solns for it ?
Nice Post it will helps lot ,
How can we handle multiple email’s by using comma separated.
any solution for (a@gmail.com,b@yahoo.co.in,c@gmail.com)
Hi All,
am using this exp”” /^[a-zA-Z0-9._%-]+@[A-Z0-9.-]+.[A-Z]{2,4}(?:(?:[,][A-Z0-9._%-]+@[A-Z0-9.-]+))?$/i “”
it’s handling this format very fine a@gmail.com,b@yahoo.co.in , while come to a@gmail.com,b@yahoo.co.in,c@gmail.com not working.
plz help me for this req
This is just what I was looking for, thanks very much!
Thanks. This RegEx pattern saved my day.
Thanks to u Very Good Explanation of Regular Expressions
askkuber.com TEam
@Bhushna for you : /^[a-zA-Z0-9._%-]+@[A-Z0-9.-]+.[a-zA-Z]{2,4}(?:(?:[,][a-zA-Z0-9._%-]+@[a-zA-Z0-9.-]+))?$/i
[…] Mailpress would throw an error on the second email which was pissing of my client’s client and my client (sigh…). The fix is pretty stratightford and easy; just replace the regular expression in Mailpress with the working one I cribbed from Zaheer. […]
Actually if you read the relevant RFCs, pretty much any character is technically valid before the final ‘@’ sign (at least in escaped or quoted sections) – the format of that part is left completely to the receiving mail server to interpret (“Abc@def”@example.com is valid, for example). The part after the ‘@’ sign is more restrictive, because only certain characters can be used in domain names.
You should certainly support apostrophes before the ‘@’, all but one of these regexes suggested will fail on valid email addresses like
jim.o’neill@example.com
Nice explanation.Now i really got the meaning of this regular expression.Untill now i was not known about the real meaning of this.This is nice and i thank you for the writter
thanx. nice explanation.
Your expression does not validate Craigslist email addresses.
Great, thanks for this post. It is useful for me.
/^[a-z0-9,!#$%&’*+/=?^_`{|}~-]+(.[a-z0-9,!#$%&’*+/=?^_`{|}~-]+)*@[a-z0-9-]+(.[a-z0-9-]+)*.([a-z]{2,})/i
not the best one, but works
IT WORKS! THANKS THANKS THANKS.
This helped me again as i forgot the regular expression and retrieved it from your site. Thanks a lot.
THANK YOU!!!
You have no idea how many websites I have gone through to find a simple explanation of this code so I may remake it without always copy-pasting just to get the job done.
You have helped a lot, thanks again.
That is nice .com it’s very useful for every one thansYou for giving this website
HI FREND
I noticed that you do not allow for domains such as co.uk co.il and I am sure there are others. you might want to revise…….. but thank anyway
@Pnina, the code will work fine on co.uk domains as the regex check after the “@” sign allows multiple periods (“.”) to be there (this allows for subdomains to be allowed as well) so as long as the last set of digits after the period are 2-4 digits long the validation will work
It allows Testyahoo@yahoo..om , if we type two dots , it is validating as true.
I didn’t know that you can validate the email address using JavaScript regular expression. I suppose it’s the best option if you need to validate in a easiest way this task.
its not working n its allow String “r@#$” if i take only “[a-zA-Z0-9._-]+” as a patten;
this one won’t work with a+b@g.com, right?
Use this regex instead
/^((([a-z]|d|[!#$%&’*+-/=?^_`{|}~]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])+(.([a-z]|d|[!#$%&’*+-/=?^_`{|}~]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])+)*)|((x22)((((x20|x09)*(x0dx0a))?(x20|x09)+)?(([x01-x08x0bx0cx0e-x1fx7f]|x21|[x23-x5b]|[x5d-x7e]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])|(\([x01-x09x0bx0cx0d-x7f]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF]))))*(((x20|x09)*(x0dx0a))?(x20|x09)+)?(x22)))@((([a-z]|d|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])|(([a-z]|d|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])([a-z]|d|-|.|_|~|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])*([a-z]|d|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF]))).)+(([a-z]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])|(([a-z]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])([a-z]|d|-|.|_|~|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])*([a-z]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF]))).?$/
This just returns the value of the email you pass it? It dosen’t result in a true/false test? How is this of any use?
ATENTION: this regex has a bug. The right syntax is:
/^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+[.]{1}[a-zA-Z]{2,4}$/
Without this modification a string like name@yahoo is a valid emalil address.
for Confused: this function return true if the user type a valid email address (name@domain.extension) and false if not.
You can call the function in this way:
var valid_email=validateEmail(document.getElementById[‘field_id’].value);
if(valid_email){ [your code] }else{ [your code] }
This validation is for you users, but you must do another validation on server side when you save your data.
these are easy expressions to understand and aplliying…really i like it a very much.
function val()
{
var email = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+[.]{1}[a-zA-Z]{2,4}$/;
}
if(document.f.t3.value.search(email)==-1)
{
alert (“plz enter tha email”);
return false;
}
Email
I modified this a bit to allow sub domains, multiple tld’s and removed validating multiple .’s (user@domain..com)
(^[a-zA-Z0-9._-]+@[a-zA-Z0-9]+([.-]?[a-zA-Z0-9]+)?([.]{1}[a-zA-Z]{2,4}){1,4}$)
will validate abc@domain.co.uk, abc@domain.com.tw, abc@sub.domain.co.uk
wewrer
This email validation script is awesome, although I replaced it with Meserias’ modification. Thanks for the script!
Actually Maserias’ modification works really well except that it accepts abc@.xyz.com. “@.” shouldn’t be together. I made a minor modification to it:
/^[a-zA-Z0-9._-]+@[a-zA-Z0-9][a-zA-Z0-9.-]+[.]{1}[a-zA-Z]{2,4}$/
So this checks to see that the domain starts with alphanumeric characters. The credit however goes to Meserias!
gr8….easy to understand and implement
Maddie’s regular expression doesn’t recognize a@b.com (exactly one character between ‘@’ and ‘.’. This modification corrects this problem:
/^[a-zA-Z0-9._-]+@[a-zA-Z0-9][a-zA-Z0-9.-]*[.]{1}[a-zA-Z]{2,4}$/
It’s a pet peeve of mine that people publish regular expressions for email addresses when they simply don’t know the standard. Every single regular expression on this page, article and comments alike, fails to validate email addresses of the form joe+list@domain.com (though to be honest I didn’t check all the older comments). People grab these expressions and throw them into their code, thinking that will make them fit some sort of standard, when they don’t.
The inability to add the +suffix to an email address undermines the usefulness of the feature even where it is accepted. PLEASE add proper support for the standard and spread the word.
There’s a good article at http://www.regular-expressions.info/email.html that discusses tradeoffs of various regular expressions for validating email addresses.
On this form I’m using a + sign in my email address.
use this . from jquery.validate.js => no, its not, the longer the better. this just works
/^((([a-z]|d|[!#$%&’*+-/=?^_`{|}~]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])+(.([a-z]|d|[!#$%&’*+-/=?^_`{|}~]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])+)*)|((x22)((((x20|x09)*(x0dx0a))?(x20|x09)+)?(([x01-x08x0bx0cx0e-x1fx7f]|x21|[x23-x5b]|[x5d-x7e]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])|(\([x01-x09x0bx0cx0d-x7f]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF]))))*(((x20|x09)*(x0dx0a))?(x20|x09)+)?(x22)))@((([a-z]|d|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])|(([a-z]|d|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])([a-z]|d|-|.|_|~|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])*([a-z]|d|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF]))).)+(([a-z]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])|(([a-z]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])([a-z]|d|-|.|_|~|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])*([a-z]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF]))).?$/
Thanks this is a simple and elegant solution to the problem.
Also thanks to Tank. I found his modification to the expression to be the best for my needs. 🙂
not bad
thanx i got alot from this
I used this expression and worked well.
/(^[a-z0-9!#$%&’*+/=?^_`{|}~-]+(.[a-z0-9!#$%&’*+/=?^_`{|}~-]+)*|”(?:[x01-x08x0bx0cx0e-x1fx21x23-x5bx5d-x7f]|\[x01-x09x0bx0cx0e-x7f])*”)(.)?@(([a-z0-9]([a-z0-9-]*[a-z0-9])?.)+[a-z]{2,}|(((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).){3}(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)))$/i
As a Java String
“(^[a-z0-9!#$%&’*+/=?^_`{|}~-]+(\.[a-z0-9!#$%&’*+/=?^_`{|}~-]+)*|”(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])*”)(\.)?@(([a-z0-9]([a-z0-9-]*[a-z0-9])?\.)+[a-z]{2,}|(((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)))$”
Of-course the length part of the email is not considered in the regular expression.
This will allow ! # $ % & ‘ * + – / = ? ^ _ ` { | } ~ in the local part and the local part can end with dot (.)
domain part can be IP or domain
greetings ..
i just want to know does this regex check dot at the beginning of email id because as per the expression we can have dot and digits at the start as well like for example:
.abc@yahoo.com
77def@fgt.com
Are these id’s valid?? please brief on that ..
Thankyou
fantastic!!!!!!!. Thanks for this simple solution.
how can we make the expression for a specific mail like gmail
To end on “@gmail.com” just use this as final part:
/@gamil.com$/
If want to check anything before @ add checks at begining.
This one will only allow leters, numbers and ‘_’ and ‘-‘ as left part of @ and must be on gmail.com
/^[0-9A-Za-z_-]+@gamil.com$/
An this other one is also to accept dot on user part, but not at start neither near the @:
/^[0-9A-Za-z_-]([.][0-9A-Za-z_-]+)*@gamil.com$/
Hope helps!
good 🙂
what if someone inputs ‘joe@support.com.com’
or @.edu.edu
??
This RegEx allows multiple email addresses if it is separated by a “;”
In a textbox if i need to validate a single email address and if two addresses are entered then this RegEx wont work.
Hi
I am VERY new too Javascript and need to validate a form for a tafe assignment. So far I have added code to validate required text fields and a drop down menu and have all the error messages come up in the one alert box. Now I am having trouble figuring out how to add the code to validate an email and have the error message appear in the same alert box as they are other fields are being validated. I hope I am making sense!!
If anyone is able to help this is my code! Please ignore all the comments! I have to add them as parrt of the assignment
function checkforblank() {
var errormessage = “”;
if (document.getElementById(‘selectmenu’).value == “”) {
/* the getElementById is determined by the id given in the below html.
For example: */
errormessage += “Please specify your title n n”;
document.getElementById (‘selectmenu’).style.borderColor = “red”;
/* .style.borderColor highlights the borders of the text fields in red when there is an error */
}
if (document.getElementById(‘fname’).value == “”) {
errormessage += “Please enter your first name n n”;
/* error message if first name field is not filled out */
document.getElementById (‘fname’).style.borderColor = “red”;
}
if (document.getElementById(‘lname’).value == “”) {
errormessage += “Please enter your last name n n”;
/* error message if last name field is not filled out */
document.getElementById (‘lname’).style.borderColor = “red”;
}
if (document.getElementById(‘enquiry’).value == “”) {
errormessage += “Please submit an enquiry n n”;
/* error message if viewer does not enter an enquiry */
document.getElementById (‘enquiry’).style.borderColor = “red”;
}
if (errormessage != “”) {
alert (errormessage);
/* alert (errormessage) displays the specified error messages that were created in the
above if statements */
return false;
}
/* return false stops the form from being submitted to the server */
// End of function
}
This regex has so many flaws I have to heavily recommend everyone ignore it. Worse than the numerous false positives others have already pointed out, it also regexs common perfectly valid email addresses. For example, the + character is very valid and not super uncommon in the left hand side of an email address.
Buyer beware, you get what you pay for when you use this regex!
here’s the regex modified to accept + signs after the first character of the address:
/^[a-z0-9._-][a-z0-9._-+]*@[a-z0-9][a-z0-9.-]*[.]{1}[a-z]{2,4}$/i
I also shortened it by adding i modifier at end, so don’t need to specify A-Z for uppercase letters. The regex still has false positives, no doubt, but no false negatives for + signs.
ya zaheer paratha koon ha?????
The solution Tank gave seems to pass all my tests and it’s a one liner. Thanks Tank
Does Tank’s address a+anything@gmail.com? It did not seem too. Jerry mentioned this.
This is a feature at gmail, add a “+(anything you pick)” before the @ on your regular gmail address, and the email will still be delivered to you, but you can send it to special filters.
Modifying Tanks to this
/^[a-zA-Z0-9._+-]+@[a-zA-Z0-9]+([.-]?[a-zA-Z0-9]+)?([.]{1}[a-zA-Z]{2,4}){1,4}$/;
Seemed to work.
Hi,
can some one please explain the meaning of below regular expression :
“^([0-9a-zA-Z]([-\.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})$”;
thanks in advance
thank you for helping to validate e-mail
elseif($_POST[‘name’]==eregi(‘^[a-zA-Z ]+$’)) is correct
error in eregi(‘^[a-zA-Z ]+$’))

gud post buddy
Very helpful!
try
/([w-.]+)@((?:[w]+.)+)([a-z]{2,4})/gi
Asslam-u-Alaikum,
Very Informative and Helpful code. specially learners and beginners.
Wasalam
Thanks everyone for your contributions.
I went with Tank’s solution and Kent’s modification. Does the trick for me!~
I’m using this and it’s working perfect:
mailRegex = /[a-z0-9!#$%&’*+/=?^_`{|}~-]+(?:.[a-z0-9!#$%&’*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])/;
This will help you validating wrong emails including: name@sample..com
Best Regards,
Mohamed
Hey,
I’m glad I came across this thread and I hope I can get some help off you guys! I’m trying to work with an previously written JavaScript function to validate an email but it’s having problems if the user enters a space at the end of their email address (it happens, especially on mobile with auto-complete etc). How could I amend the following code to allow a space at the end?
function checkMail(emailInput) {
filter = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+.[a-zA-Z]{2,4}$/;
if(!filter.test(document.lpform.email.value)) {
$(“#email”).addClass(“error”).focus();
$(“#email”).blur();
document.getElementById(‘dataStatus’).style.display=”block”;
return false; }
return true;
}
Thanks so much! I really appreciate it. =D
Ok, I just added s and that worked…
filter = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+.[a-zA-Zs]{2,4}$/;
Thanks anyway.
