I have found a nice form validation plugin in this website:http://formvalidator.net/index.html
While I was trying to implement server-side validation, the plugin doesn't seems to work. It states that it would send the url via POST method to the url that I have declared in the attribute data-validation-url.However when I tried to echo the post variable, it doesn't seems to show in the web browser.
Could someone help to look into it? Maybe I might have done something wrong somewhere. Apologies, I am quite new to programming! :)
Take a look at this page section:http://formvalidator.net/index.html#security-validators

echo json_encode($response);
EDITED: I missed completely a slash in the input of the username, and that was the problem, test it now, now it fires the post request.
You only need to add method post on the form.
Try to use proper indentation it's easier to read and no one will blame you for doing it.

Check this out, seems to be working fine.
Good Luck.

Sorry if this is a relatively basic question but I'm getting a little bit frustrated, and this is the first time I'm using GitHub Pages
What I want is:
Accept text in form
Compare text in form with password "pass"
if correct, go to a different html site
else, do nothing
thanks in advance
<!DOCTYPE html>
<html>
<head>
<title>Page</title>
</head>
<body>
<form onSubmit="checkPass(this)">
<label>Password:</label>
<input type="text" name="Password" id="pwd" size="20">
<input type="Submit" name="Submit">
</form>
<script>
function checkPass(passForm) {
var password = document.getElementById('pwd');
if (password == "pass"){
windows.open("Website extension here")
}
}
</script>
</body>
</html>
But anyone can view source and open the website right? Everything is right except you missed .value. Add a return false and make windows as window:
function checkPass() {
var password = document.getElementById('pwd').value;
if (password == "pass") {
window.open("https://example.com")
}
}
<form onSubmit="checkPass(); return false;">
<label>Password:</label>
<input type="text" name="Password" id="pwd" size="20">
<input type="Submit" name="Submit">
</form>
The above code will not work in sandbox. So try it using CodeSandbox Demo.
Going through some exercise which including JQuery + PHP combined together .The part I am not completely understand is in the Jquery code when the if statement starts ,can someone please explain from this point on what's going on?
HTML code:
<html>
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
<form action="" method="post">
<label for="name">Name:</label><br>
<input type="text" name="name"><br><br>
<label for="email">Email:</label><br>
<input type="text" name="email" id="email" autocomplete="off"><br><br>
<label for="password">Password:</label><br>
<input type="text" name="password"><br><br>
<input type ="submit" name="submit" value="Sign up">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="script.js" type="text/javascript"></script>
</body>
</html>
PHP code:
<?php
if(! empty($_GET['email'])){
$email=filter_var($_GET['email'],FILTER_VALIDATE_EMAIL);
if($email){
$con="mysql:host=localhost;dbname=eshop;charset=utf8";
$db= new PDO($con,'root','');
$query=$db->prepare("SELECT email FROM users WHERE email = ?");
$query->execute([$email]);
$email=$query->fetch(PDO::FETCH_ASSOC);
if($email){
echo true;
}
}
}
JQuery code:
$('#email').on('keyup', function(){
var userEmail= $(this).val().trim();
$('#result').remove();
var emailRegex= /^[_a-z0-9-]+(.[_a-z0-9-]+)*#[a-z0-9-]+(.[a-z0-9-]+)*(\.[a-z]{2,3})$/i;
if(emailRegex.test(userEmail)){
$.get('check_email.php',{email:userEmail},function(res){
if(res ==1){
$('#email').after('<span id="result">*Email is taken</span>');
}
});
}
});
I'm trying to alert the values of the form elements but this isn't functioning even at its simplest: getting the elements of the form then alerting a string.
The alert fires when it's by itself, but not when I put the form's data in the variable. Why?
I'm sure there's probably a very simple mistake in here somewhere, but I'm stumped.
<!DOCTYPE html>
<html>
<head>
<!-- ISTE240 Exercise 5b -->
<meta charset=utf-8 />
<title>Get elements from a form</title>
<script>
function getFormValues() {
// function to send first and last names to an 'alert' message.
alert("test");
var form = document.getElementById(“regForm”).elements;
}
</script>
</head>
<body>
<p>JavaScript Exercise 5b </p>
<form id="regForm" onsubmit="getFormValues()">
First name: <input type="text" name="fname" value="Boo"><br>
Last name: <input type="text" name="lname" value="Radley"><br>
<input type="submit" value="Submit">
</form>
</body>
</html>
By default form tag will try to submit form values. You must prevent default behavior, demo below
document.querySelector('#regForm').onsubmit = function(e){
e.preventDefault();
alert('a');
var form = document.getElementById("regForm").elements; //<-- wrong syntax, must be "
console.log(form);
}

I am new to angular js. please help me with the below issue
I have a form with a controller loginController. I have two text boxes user.email and user.password.
I want to post the data to servlet onclick of the Log in button.
I have written the following code, but when i click Log in, the data is not getting posted on to the server. Also there is no error message.
Below is my JSP file
`
<html ng-app="practiceApp">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
<link rel ="stylesheet" type="text/css" href="bootstrap.min.css"/>
</head>
<body>
<script type="text/javascript" src="angular.min.js"></script>
<script type="text/javascript" src="practice.js"></script>
<form name='login' ng-controller='loginController' ng-submit="login()">
<div>
{{hello}}
<label>Email</label>
<input type="email" name="email" ng-model="user.email" required/>
<span ng-show='login.email.$dirty && login.email.$error.required'>Required</span>
<span ng-show='login.email.$dirty && login.email.$error.email'>Not a valid email</span>

<span ng-show='login.password.$dirty && login.password.$error.required'>Required</span>
<button ng-disabled="login.$invalid">Log in</button>
</div>
</form>
</body>

`
JavaScript File
`
var app = angular.module('practiceApp',[]);
app.controller('loginController',function($scope,$http){
$scope.login = function(){
$http({
method: 'POST',
url:'/login',
headers:{'Content-Type':'application/json'},
data:$scope.user
}).success(function(data){
$scope.status=data;
});
}
});
`
I have tried all the solutions that are available but couldn't find any result.. Kindly help on this
Your <button> does not cause the form to submit. Change to <input type="submit" ng-disabled="login.$invalid">Log in</button> or remove ng-submit from the form and add ng-click="login()" to the <button>.
Im trying to put my "register.php" into fancybox, however I cant make it connect there.
To call up fancybox I use this:
<body>
Open
<div id="test" style="display:none;width:400px; height:600px;"
**Content here**
<!--Javascript for fancybox-->
<script type="text/javascript">
$(document).ready(function() {
$(".fancybox").fancybox();
});
</script>

include_once 'includes/register.inc.php';
