Regexp To Validate Email Address Except Some Domain

Mar 1, 2011

I want to check the email address type in a contact form but want to reject it if it's from a certain domain I actually use this regexp : /^[a-zA-Z0-9_.-]+@([a-zA-Z0-9-]+.)+[a-zA-Z0-9]{2,4}$/ (taken from the jquery validationengine) to check if the email address is correctly formated but I'd like to reject it if contains hotmail between the @ and the. I tried many things but couldn't get something that works.

Validate EMail With RegExp...

Nov 3, 2005

My understanding of regular expressions is rudimentary, at best.

I have this RegExp to to a very simple validation of an email-address, but it turns out that it refuses to accept mail-addresses with hypens in them.

Can anybody please help me adjust it so it will accept addresses like dag-sunde@test-domain.net too?

Here's what got:

function validateEmail(eMail) {
return /^(w+.)*(w+)@(w+.)+([a-zA-Z]{2,4})$/.test(eMail);
}

Require Specific Domain For Registering Email Address

Apr 26, 2011

I have an issue with a registration form. What I would like to do is only allow a certain email domain in the 'email' field. Eg. Only allowing @gmail.com email addresses, and all others would receive an error. This is the line of code that I believe needs changing:

function isEmail(valor){if(/^w+([.-]?w+)*@w+([.-]?w+)*(.w{2,4})+$/.test(valor)){return(true)}else{return false;}}

I am not too familiar with this but through my hours of research, I believe that I need to add something to this line.

/^[a-zA-Z0-9_-]+([.][a-zA-Z0-9_-]+)*@[a-zA-Z_-]+([.][a-zA-Z0-9_-]+)*$/

I'm using this to try to validate a small subset of the valid e-mail

dashes). I've tested it and it seems to work....

JS - Email Regexp With ONLY One Period Possible Before @

Feb 21, 2010

I am attempting to do a basic email format validation in JavaScript on a very basic form with fields for name, address, email, etc.

Requirements: A period can occur before the @, but not twice in a row -- as in jane.doe@xyz.com but not jane..doe@xyz.com. Email must start with a letter. I'm also allowing underscores and hyphens before the @, but I'm not worrying about whether there's only one of each -- I'm just allowing those. Must end in .com, .net, .org. Nothing else.

[Code]...

I have read extensively on this site and several others and haven't found a solution to the "one and only one period allowed in succession, but not required" problem. I haven't found a successful way to limit periods to only 1 in a row yet still have the rest of the validation work properly. I get the symbols in general, but as a newbie can't seem to make them do this one thing that I want them to do.

Regexp To Extract Address: City, State, And

Oct 17, 2007

I am working with this regexp to extract address: city, state, and zip. This version kinda works but it extracts one element of an array instead of three and keeps my "city" too long, including all text before it.
.....................
var regex = /s*(.*)s*,s*([A-Z]{2})s+(d{5}(-d{4})?)s*/g;
function doit(){
var arr = d.innerHTML.match(regex);
if(arr.length=3){
d2.innerHTML = arr[0]+" | "+arr[1]+" | "+arr[2];
}else{
d2.innerHTML = "Found "+arr.length+" matches";
}
}
//-->
</script>
.......................
<div id="myDiv">
Some text here, not always break after <br>New Haven, CT 06460 plus whatever text here too
</div>

RegExp Format To Only Validate (###) ###-#### In Form?

Feb 13, 2009

I am working on a form that gets validated both on change and on submit (assignment). For the phone number, I want to validate so that the form will ONLY accept numbers entered in the following format: (###) ###-####
(ex. (555) 867-5309 ). I am new to JS, but am pretty sure this can be accomplished via using and comparing a regExp? If so, what is the code for that?

The closest one I can find is the following:
^(()?(787|939)()|-)?([0-9]{3})(-)?([0-9]{4}|[0-9]{4})$

Obviously, I do not only want to limit it to 787 or 939, so I need to remove that). Although, this accepts a variety of options that I do not want, like no parenthesis, only two numbers for area code, or no dashes, etc. I sort of understand how this works, but am unsure how to make the elements in the format REQUIRED as opposed to optional

Protecting Email Address From Spammers?

Jan 8, 2011

I am trying to prevent an email address from being spammed as spammers use spidering tools to scan the internet for exposed email addresses in plain text.

I am using a technique and I'm not sure whether it will deter spam bots.

I have an external Javascript file with the following variables:

var usr = "mark";
var at = "@";
var domain = "fullmarksdrivingschool.co.uk";

[Code].....

When I open the web page in a browser the email address displays correctly but does this technique work to prevent spammers from indexing the email address?

Javascript Checking Email Address

May 1, 2002

I need a simple js function that will check if the value (an email address) in two text fields match.

If someone enters creole@creole.com in "fieldOne" and creoel@creole.com in field two it would throw an error. If they matched, the form would submit silently.

Can someone help me out? I think it should be easy, and I'm trying to do it myself, I'm just not good enough at js.
