I need this input informs when the user does not use a valid email address.
takes the form gets red border or a message appears (a hover) next to the field
HTML
<body ng-controller="simulacaoController">
<input type="text" ng-class="{red: cadastro.$invalid}" ng-model="email" name="email" placeholder="E-Mail" ng-pattern="mascaraEmail" class="last" required />
</body>
AngularJS
angular.module("simulacao", []);
angular.module("simulacao").controller("simulacaoController", function($scope){
$scope.mascaraEmail = "/^[a-zA-Z0-9][a-zA-Z0-9\._-]+#([a-zA-Z0-9\._-]+\.)[a-zA-Z-0-9]{2,3}/";
});
CSS
.red {
border: solid 1px red;
}
My code: https://fiddle.jshell.net/kvxcsync/2/
You could use the input type email:
<input type="email" ... />
More about input types.
AngularJS has email validation so no need to use ng-pattern for this
<body ng-controller="simulacaoController">
<form name="myForm">
<input type="name" ng-class="{red: cadastro.$invalid}" ng-model="text" name="email" placeholder="E-Mail" class="last" required />
<form name="myForm" ng-controller="Ctrl">
Email: <input type="email" name="input" ng-model="text" required>
<br>
<span class="red" ng-show="myForm.email.$error.email">
Not a valid email!
</span>
</form>
</body>
Reference link
You have to add input type ="email" and add <form></form> Tags for proper form validation
<body ng-controller="simulacaoController">
<form>
<input type="email" ng-class="{red: cadastro.$invalid}" ng-model="email" name="email" placeholder="E-Mail" ng-pattern="mascaraEmail" class="last" required />
</form>
</body>

I am new to JavaScript. I have a form in an html file that has some text fields. When someone click the submit button, a JavaScript function is called to do some work (in this case, a simple alert). It works as I wanted, when I fill the text fields and click the submit button it calls the JavaScript function and the function shows an alert. However, the problem is, when a user clicks the submit button keeping some fields empty and/or not following the pattern of an email address, it calls the JavaScript function (even though HTML 5 has shown warnings in the form). I want the JavaScript function should only be called if there are no HTML warnings, I mean no empty fields and the user must follow the email pattern. Thank you for your help.
HTML code:
<form id="myForm" method="post" role="form" class="contactForm">
<input type="text" name="name" class="form-control" id="name" placeholder="Your Name" data-rule="minlen:4" data-msg="Please enter at least 4 chars" />
<input type="email" class="form-control" name="email" id="email" placeholder="Your Email" data-rule="email" data-msg="Please enter a valid email" />
<textarea class="form-control" name="message" id="message" rows="5" data-rule="required" data-msg="Please write something" placeholder="Message"></textarea>
<button id="submitFormData" onclick="SubmitFormData();" type="submit" class="button button-a button-big button-rouded">Send Message</button>
</form>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script src="alert.js"></script>
Javascript Code (alert.js):
function SubmitFormData() {
var name = $("#name").val();
var email = $("#email").val();
var message = $("#message").val();
alert("SHOW SOMETHING HERE");
}
you can use required attribute in the input and one more thing you can call the SubmitFormData() onsubmit form here's your modified code :
function SubmitFormData() {
var name = $("#name").val();
var email = $("#email").val();
var message = $("#message").val();
alert("SHOW SOMETHING HERE");
}
<form id="myForm" method="post" role="form" class="contactForm" onsubmit="SubmitFormData();">
<input type="text" name="name" class="form-control" id="name" placeholder="Your Name" data-rule="minlen:4" data-msg="Please enter at least 4 chars" required/>
<input type="email" class="form-control" name="email" id="email" placeholder="Your Email" data-rule="email" data-msg="Please enter a valid email" required/>
<textarea class="form-control" name="message" id="message" rows="5" data-rule="required" data-msg="Please write something" placeholder="Message" required></textarea>
<button id="submitFormData" type="submit" class="button button-a button-big button-rouded">Send Message</button>
</form>
<script src="http://code.jquery.com/jquery-latest.js"></script>
You just need to add the required attribute to your fields, see
Here is the best working solution for what you want to achieve by using the
form validation JS plugin.

The easiest way was to provide an HTML only solution based on a form element's required attribute since the browser will take over the validation of required elements also by their element/control type ...
<form id="myForm" method="post" role="form" class="contactForm" action="https://stackoverflow.com/">
<input
required
type="text" name="name" id="name"
class="form-control" placeholder="Your Name"
/>
<input
required
type="email" name="email" id="email"
class="form-control" placeholder="Your Email"
/>
<textarea
required
name="message" id="message"
class="form-control" rows="5" placeholder="Message"></textarea>
<button
type="submit" id="submitFormData"
class="button button-a button-big button-rouded">Send Message</button>
</form>
A generic custom validation is much more complex and labour-intensive ...
function validateControValue(elm) {
let isValid = true;
const elmType = elm.type;
if (elmType !== 'button' && elmType !== 'submit') {
const $elm = $(elm);
const isEmpty = ($elm.val().trim() === '');
if (isEmpty) {
$elm.val('');
$elm.addClass('validation-error');
} else {
$elm.removeClass('validation-error');
}
// non empty is valid, empty is invalid.
isValid = !isEmpty;
}
return isValid;
}
function handleValidFormSubmit(/* evt */) {
const isValidSubmitData = Array
.from(this.elements)
.every(validateControValue);
return isValidSubmitData;
}
function main() {
$('#myForm').on('submit', handleValidFormSubmit)
}
$(document)
.ready(main);
.validation-error {
border: 1px solid #f00;
}
<form id="myForm" method="post" role="form" class="contactForm" action="https://stackoverflow.com/">
<input
type="text" name="name" id="name"
class="form-control" placeholder="Your Name"
/>
<input
type="email" name="email" id="email"
class="form-control" placeholder="Your Email"
/>
<textarea
name="message" id="message"
class="form-control" rows="5" placeholder="Message"></textarea>
<button
type="submit" id="submitFormData"
class="button button-a button-big button-rouded">Send Message</button>
</form>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<!-- <script src="alert.js"></script> //-->
I am using the PHP & MySQL to submit a form with following code and using isset function in PHP to submit the value to database.
<div class="display">
<form action="" method="POST">
<div>
<input type="text" name="name" placeholder="Your Name" required="required">
</div>
<div>
<input type="text" name="phone" id="phone" placeholder="Mobile" required="required" onblur="check();">
<br/>
<span id="e_mobile"></span>
<?php if(isset($_GET["r"])){ ?><p>Invalid number; must be ten digits. Please submit your query again</p><?php } ?>
</div>
<div>
<input type="text" name="landline" id="landline" placeholder="Alternate Number" required="required" onblur="check1();">
<br/>
<span id="e_landline"></span>
</div>
<div>
<input type="email" name="email" placeholder="Email" required="required">
</div>
<div>
<input type="text" name="address" placeholder="Your Address" required="required">
</div>
<div>
<input type="hidden" value="0" name="salesid"/>
</div>
<input type="submit" name="submit" value="Submit">
</form>
</div>
Now I want once the user click submit button once the button should freeze; as of now if the user clicks the submit button more than once(by intentionally or by mistake) the same information is getting submitted in the database more than once.
What to do in this circumstance?
Try with JQuery:
First add an ID to your form
<form action="" method="POST" id="form">
After that add script:
<script type="text/javascript">
$(document).ready(function() {
$("#form").submit(function(e){
$("input[type='submit']").attr("disabled","disabled");
});
});
</script>
You can add PHP Captcha to prevent user click again.
Please review below two urls which includes demo too.

Why doesn't my ng-show work when I give ng-app a name and declare it?
https://jsfiddle.net/jzhang172/f7mrkf48/
$(function(){
var app = angular.module('myApp', []);
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<div ng-app="myApp">
<form name="formMe">
1<input type="text"><br>
2<input type="text"><br>
Email<input name="email" ng-model="email" required>
<span ng-show="formMe.email.$touched">You touched me</span><br>
<input type="submit" ng-disabled="formMe.email.$invalid">
</form>
</div>
You need to use name attribute for your form and use that form name instead of module name myApp to validation form field. So use name property in your form tag name="myForm" and for validation use myForm.email.$invalid
like:
<form name="myForm">
1<input type="text"><br>
2<input type="text"><br>
Email<input type="email" name="email" ng-model="email" required>
<span ng-show="myForm.email.$touched">You touched me</span><br>
<input type="submit" ng-disabled="myForm.email.$invalid">
</form>
Your code snippet has syntax error, the exact code snippet after fixing the error is working.
var app = angular.module('myApp', []);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<div ng-app="myApp">
<form name="formMe">
1
<input type="text">
<br>2
<input type="text">
<br>Email
<input name="email" ng-model="email" required>
<span ng-show="formMe.email.$touched">You touched me</span>
<br>
<input type="submit" ng-disabled="formMe.email.$invalid">
</form>
</div>
I am currently working on a 'contact form', I have been working on this for quite a while but, I just can't figure out how to make JavaScript email the form to my email adress.
This is my code :
<form id="myform" action="mailto:contact#anika.nl">
<label for="FirstName">Name:</label>
<input id="FirstName" name="FirstName" type="text" />
<label for="EMail">Email:</label>
<input id="EMail" name="EMail" type="text" />
<label for="Message">Message:</label>
<textarea id="Message" cols="20" name="Address" rows="5"></textarea>
<input name="submit" type="submit" value="Submit" />
</form>
<script type="text/javascript">// <![CDATA[
var frmvalidator = new Validator("myform");
frmvalidator.addValidation("FirstName","req","Please enter your First Name");
frmvalidator.addValidation("FirstName","maxlen=20", "Max length for FirstName is 20");
frmvalidator.addValidation("Email","maxlen=50");
frmvalidator.addValidation("Email","req");
frmvalidator.addValidation("Email","email");
// ]]></script>
Does someone see what I'm doing wrong/what's missing?
So I have a basic form that takes in Name, Email, Date of Arrival, Date of Departure and Comment with a big "Send" button. Here is the code for that:
<form class="form" id="form1" action="mailto:myemail#email.com" method="post">
<p class="name">
<input name="Name" type="text" class="validate[required,custom[onlyLetter],length[0,100]] feedback-input" placeholder="Name" id="name" />
</p>
<p class="email">
<input name="Email" type="text" class="validate[required,custom[email]] feedback-input" id="email" placeholder="Email" />
</p>
<p class="email">
<input name="Date Of Arrival" type="date" class="validate feedback-input" id="date" placeholder="Date Of Arrival" />
</p>
<p class="email">
<input name="Date Of Departure" type="date2" class="validate feedback-input" id="date2" placeholder="Date Of Departure" />
</p>
<p class="text">
<textarea name="Text" class="validate[required,length[6,300]] feedback-input" id="comment" placeholder="Comment"></textarea>
</p>
<div class="submit">
<input type="submit" value="SEND" id="button-blue"/>
<div class="ease"></div>
</div>
</form>
It successfully opens up my mail client with an email. The issue is that this is what is in the body of the email:
Name+%250D%250A+=Name+Test&Email+%250D%250A=test%40email.com&Date+Of+Arrival+%250D%250A=09%2F04%2F2015&Date+Of+Departure+%250D%250A=24%2F04%2F2015&Text=This+is+a+test+comment
How can I style this? I have looked online and can't figure it out.
For this example, this is how I would like the email body to look:
Name: Name Test
Email: test#email.com
Date of Arrival: 09/04/2015
Date of Departure: 24/04/2015
Message Body: This is a test comment.
I wouldn't mind having the subject field repopulated too with "booking request" or something.
Thanks!
It's quite easy. All you have to do is specify your Content Type (MIME). Change your form to:
<form class="form" id="form1" action="mailto:myemail#email.com" method="post" enctype="text/plain">
Define enctype in form tag:
<form class="form" id="form1" action="mailto:myemail#email.com" method="post" ENCTYPE="text/plain">
Unfortunately what you can do here in terms of formatting is very limited. I would suggest to have a look at this answer:
