Validate Format of an Email Address using Jquery.validate.js [closed]
(1 answer)
Closed 5 years ago.
I have an HTML form that contains an input which requests a users email address. There are several email addresses that if entered should not allow the form to submit e.g. #donotsubmit.com, #donot.submit.com.
Using jQuery, is it possible to prevent the form from submitting if the input contains these strings? The code looks like this:
<input class="form-control emailrequired" id="Email" name="Email" placeholder="Email" type="text" value="" />
<script type="text/javascript">
$().ready(function () {
$.validator.addMethod("cRequired", $.validator.methods.required, "Please ensure this field is complete");
$.validator.addClassRules("emailrequired", { cRequired: true, email: true });
});
</script>
Edit:
Updated script using jQuery Array. The issue I am having is that the jQuery Validate is not using the inArray statement to mark the field as valid/invalid.
<input class="form-control emailrequired" id="Email" name="Email" placeholder="Email" type="text" value="" />
<script type="text/javascript">
$().ready(function() {
$.validator.addMethod("cRequired", $.validator.methods.required, "Please ensure this field is complete");
$.validator.addMethod("domain", function(value, element) {
var emailAddress = $('#Email').val();
var emailDomain = emailAddress.substr(emailAddress.search('#') + 1);
var invalidAddresses = ["donotsubmit.co.uk"];
if (jQuery.inArray(emailDomain, invalidAddresses) !== -1) {
event.preventDefault();
}
}, "Please use a personal email account");
$.validator.addClassRules("emailrequired", {cRequired: true, email: true, domain: true});
});
</script>

How can I validate an email address in JavaScript?

Referring to this issue:
How can I set a minimum length for a field with jQuery?,
<form id="new_invitation" class="new_invitation" method="post" data-remote="true" action="/invitations" accept-charset="UTF-8">
<div id="invitation_form_recipients">
<input type="text" value="" name="invitation[recipients][]" id="invitation_recipients_0"><br>
<input type="text" value="" name="invitation[recipients][]" id="invitation_recipients_1"><br>
<input type="text" value="" name="invitation[recipients][]" id="invitation_recipients_2"><br>
<input type="text" value="" name="invitation[recipients][]" id="invitation_recipients_3"><br>
</div>
<input type="submit" value="Send invitation" name="commit">
</form>
What would the code be for settting a minimum length for a field with jQuery?
$('#new_invitation').submit(function(event) {
if ($('#invitation_form_recipients input').filter(function() {
return $(this).val();
}).length == 0) {
// All the fields are empty
// Show error message here
// This blocks the form from submitting
event.preventDefault();
}
});
How can I validate that every field input have a valid email address with jQuery? In the above code?
You probably want to use a regex like the one described here to check the format. When the form's submitted, run the following test on each field:
var userinput = $(this).val();
var pattern = /^\b[A-Z0-9._%-]+#[A-Z0-9.-]+\.[A-Z]{2,4}\b$/i
if(!pattern.test(userinput))
{
alert('not a valid e-mail address');
}
This regex can help you to check your email-address according to all the criteria which gmail.com used.
var re = /^\w+([-+.'][^\s]\w+)*#\w+([-.]\w+)*\.\w+([-.]\w+)*$/;
var emailFormat = re.test($("#email").val()); // This return result in Boolean type
if (emailFormat) {}
Email: {
group: '.col-sm-3',
enabled: false,
validators: {
//emailAddress: {
// message: 'Email not Valid'
//},
regexp: {
regexp: '^[^#\\s]+#([^#\\s]+\\.)+[^#\\s]+$',
message: 'Email not Valid'
},
}
},
This : /^[a-zA-Z0-9._-]+#[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/i is not working for below Gmail case
gmail.#gmail.com
gmail#.gmail.com
Below Regex will cover all the E-mail Points: I have tried the all Possible Points and my Test case get also pass because of below regex
I found this Solution from this URL:
Regex Solution link
/(?:((?:[\w-]+(?:\.[\w-]+)*)#(?:(?:[\w-]+\.)*\w[\w-]{0,66})\.(?:[a-z]{2,6}(?:\.[a-z]{2})?));*)/g
This :
var email = /^[a-z0-9._%+-]+#[a-z0-9.-]+\.[a-z]{2,4}$/;
function mailValidation(val) {
var expr = /^([\w-\.]+)#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$/;
if (!expr.test(val)) {
$('#errEmail').text('Please enter valid email.');
}
else {
$('#errEmail').hide();
}
}
I want to do a very basic jQuery validation of an email via a regex on submit. My HTML:
<form action="POST" id="form">
<input type="email" id="customer_email" placeholder="email here" />
<input type="submit" />
</form>
JS:
$('#form').submit(function() {
var email_reg = /^([\w-\.]+#([\w-]+\.)+[\w-]{2,4})?$/;
var emailinput = $('#customer_email').value();
if (email_reg.test(emailinput) == false) {
window.alert('no good');
}
});
To my understanding, for this to work I need to get the value of the input via email input (which I do on line 4) and run a regex on it.
When submit is clicked, the standard input error appears on the form, and not the window alert. Feel free to view a Codepen outlining this here:
http://codepen.io/anon/pen/oYmJLW?editors=1010
You need to add event.preventDefault() to prevent the actual form submission, and use .val() instead of .value() on the input.
$('#form').submit(function(event) {
event.preventDefault();
var email_reg = /^([\w-\.]+#([\w-]+\.)+[\w-]{2,4})?$/;
var emailinput = $('#customer_email').val();
if (email_reg.test(emailinput) == false) {
window.alert('no good');
}
});
By declaring your input as type="email" your browser will do the validity checking (you don't need to do it yourself then), if you want to circumvent that use type="text".
I'm trying to access the value of an input field of a form.
The text input of the form is:
<input type="email" name="email" class="form-control" id="email">
And in my JS file I tried this:
var avisoPago = {
email: function () {
return $('#email').val();
},
...
If I try to print out in the console the email value with email or this.email:
I get this result:
In the case of email: [object HTMLInputElement]
In the case of this.email: function () { $('#email').val(); }
Now if the user types john#example.com how may I get that value in order to use it? (I want to insert that value later on into a MongoDB file).
I have a webpage where a user submits a form containing an email field and a confirm email field.
How do I check to make sure both of these fields equal the same thing?
<form>
Email: <input type="text" name="email"><br /><br />
Confirm Email: <input type="text" name="confirmemail"><br /><br /><br /><br />
<input type="submit" value="Submit">
</form>
With jQuery, but no error handling, I'd suggest:
$('form').on('submit', function() {
return $('input[name=email]').val() == $('input[name=confirmemail]').val();
});

Easiest way would be to use Javascript as you can stop form submission before it goes to your php file. However it is still good practice to verify the data entered with the php file as well as there are some programs that will allow you to change data being submitted in a form after javascript checks are made.
<script>
function checkMatch() {
var email = document.getElementById('email').value;
var emailConfirm = document.getElementById('emailConfirm').value;
if (email != emailConfirm) {
alert("Email addresses are not the same.");
return false; //Returning 'false' will cancel form submission
} else {
/*
place the return true; at the end of the function if you do other
checking and just have if conditions and return them as false. If
one thing returns false the form submission is cancelled.
*/
return true;
}
}
</script>
And change your form to have onSubmit
<form method="post" action="submit_query.php" onSubmit="checkMatch()">
Add id's to your email inputs such as: email and emailConfirm. You can change them if you wish but just for an example I used those.

Validate email address in Javascript?
How do I validate email on the client side using javascript when the server side cannot validate? From my understanding Javascript can be turned off so how can this be achieved and prevent me from receiving PCI warnings?
$(document).ready(function() {
var clearMePrevious = "";
// clear input on focus
$("#email").focus(function() {
if($(this).val()==$(this).attr("title")) {
clearMePrevious = $(this).val();
$(this).val("");
}
});
// if field is empty afterward, add text again
$("#email").blur(function() {
if($(this).val()=="") {
$(this).val(clearMePrevious);
}
});
$('#submitemail').click(function() {
app.ajax.load({
reqName : 'emailSubmit',
url: '$httpUrl('Bronto-OptIn')$?email=' + $('#email').val(),
selector : '#emailbox',
callback: function(responseText, textStatus) { }
});
return false;
});
});
<form id="emailsignup_form" name="emailsignup_form" method="post" action="$httpUrl('Bronto-OptIn', 'fid', 'information')$">
<div class="fl"><input class="email-signup-input" type="text" title="Enter Your Email Address" value="Enter Your Email Address" name="email" id="email" /></div>
<div class="fl"><button class="email-signup-btn" value="Submit" name="submitemail" id="submitemail">Submit</button></div>
<div class="clear"> </div>
If client side validation is necessary I would put in a fallback for the case that javascript is not enabled -
<script type="javascript">
/* Wire up form submittal */
</script>
<noscript>
<p>JavaScript is required to use this form, please enable JavaScript in your browser!</p>
</noscript>
