Validating an email field based on a specific domain
I have a site for which the user will need a login. The client gets access only from users of his domain. I need to validate this field based on the email domain address. i.e. only allow email addresses with @ mycompany.com.
Can this be done using the jquery.validate plugin? I see where you can check if it is indeed a valid email, but I would like to make sure it matches a certain pattern (@ mycompany.com).
Any help would be appreciated!

Just use jQuery validation and compare the string with to make sure the email ends with the expected domain .
This way you know that the email message appears to be valid and has the correct domain.
Here is a possible method for checking a domain. It doesn't really require jQuery.
/**
* Checks that the user email is of the correct domain.
*
* userInput: potential email address
* domain: Correct domain with @, i.e.: "@mycompany.com"
* Returns: true iff userInput ends with the given domain.
*/
function checkDomain(userInput, domain) {
// Check the substring starting at the @ against the domain
return (userInput.substring(userInput.indexOf('@')) === domain;
}

In this example my domain is "@uol.edu.pk". You can do it like this.
$(document).ready(function (e) {
$('#SubmitButton').click(function () {
var email = $('#form-email').val();
// Checking Empty Fields
if ($.trim(email).length == 0 || $("#form-first-name").val() == "" || $("#form-password").val() == "" || $("#Password1").val()=="") {
alert('All fields are Required');
e.preventDefault();
}
if (validateEmail(email)) {
alert('Good!! your Email is valid');
}
else {
alert('Invalid Email Address');
e.preventDefault();
}
});
});
// Function that validates email address through a regular expression.
function validateEmail(pEmail) {
var filterValue = /^[\w\-\.\+]+\@[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,4}$/;
if (filterValue.test(pEmail)) {
if (pEmail.indexOf('@uol.edu.pk', pEmail.length - '@uol.edu.pk'.length) != -1)
{
return true;
}
else {
alert("Email Must be like(yourName@uol.edu.pk)");
return false;
}
}
else
{
return false;
}
}
