How to use Parsley.js with dynamic content - forms

I am using parsley.js 2.0.2. for client side form validation.
Now I noticed on the Parsley Website that parsley 2.x has dynamic form validation.
I have a form on my page with parsley. It works correctly and does validate. Now on the same page I have a link that dynamically adds a form from an external file. Issue is now parsley.js won't validate the newly added form.
On the parsley website they have an example where one can use JavaScript to validate but I tried it and it does not work. Here is the snippet code of the example:
<script src="jquery.js"></script>
<script src="parsley.min.js"></script>
<form id="form">
...
</form>
<script type="text/javascript">
$('#form').parsley();
</script>
I am aware that the content in the DOM changed but is there a way that I can tell parsley to validate this newly added form or something that will trigger the validation process?
I will appreciate the help!
Thanks
Here is my form on the index.php page (This form does successfully validate):
<form action="server.php" method="post" name="main-form" id="myForm" data-parsley-validate>
<div>
<label for="njsform-name">Name</label>
<input name="name" type="text" id="njsform-name" placeholder="Mike" data-parsley-required="true" data-parsley-minlength="2">
</div>
<div>
<label for="njsform-email">Surname</label>
<input name="email" type="text" id="njsform-email" placeholder="Gates" data-parsley-required="true" parsley-minlength="2">
</div>
<div class="submitWrap">
<input class="submit" type="submit" value="Apply Now" />
</div>
Here is the link that gets the external content
<ul class="services-list">
<li><a class="s-option" href="views/form-short_term_loans.php">My Link</a></li>
</ul>
Here is the code I am using to dynamically change the content (does successfully retrieve external form and populates):
$(document).ready(function() {
var hash = window.location.hash.substr(1);
var href = $('.services-list li a').each(function(){
var href = $(this).attr('href');
if(hash==href.substr(0,href.length-5)){
var toLoad = hash+'.html #form-section';
$('#form-section').load(toLoad)
}
});
$('.services-list li a').click(function(){
var toLoad = $(this).attr('href')+' #form-section';
$('#form-section').hide('fast',loadContent);
$('#load').remove();
$('#intro-section').append('<span id="load">Getting required form...</span>');
$('#load').fadeIn('normal');
window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-5);
function loadContent() {
$('#form-section').load(toLoad,'',showNewContent())
}
function showNewContent() {
$('#form-section').show('normal',hideLoader());
}
function hideLoader() {
$('#load').fadeOut('normal');
}
return false;
});
});
The second form is just a duplicate but the form id is myForm2 and the name second-form

Add a call to
$('#xxxxxx').parsley();
After the load of the new form. With xxxxx the id of the new form inserted in the DOM

Amp-form does not redirect to another page

I have one input bar which must redirect to another https page (contains google-search) on submit. The code of the form is the next:
<form class="navbar-form navbar-left hide-inputs buscadoMovilLine" role="search" target="_blank" action-xhr="https://www.tuotromedico.com/buscadorg.php" action="https://www.tuotromedico.com/buscadorg.php" method="get">
<div class="form-group buscador">
<input class="SearchInputMovil2 inl" type="text" placeholder="Buscar..." class="form-control" name="q">
<button class="inl" type="submit" class="btn btn-default"><i class="fa fa-search lupaBuscarMovilBoton2" aria-hidden="true"></i></button>
</div>
</form>
I have added the amp-form extension too. The official documentation says this:
Redirecting after a submission
amp-form also allows publishers to redirect users to a new page after a submission happens through AMP-Redirect-To response header.
Note that you'd also have to update your Access-Control-Expose-Headers
response header to include AMP-Redirect-To to the list of allowed
headers.
The redirect URL must be absolute HTTPS URL otherwise AMP will throw
an error and redirection won't happen.
https://www.ampproject.org/es/docs/reference/components/dynamic/amp-form
But im not sure how have i to specify that.
I know 2 ways, this is for node:
app.post('/register', function (req, res) {
let form = new formidable.IncomingForm();
form.parse(req, function (err, fields) {
res.setHeader('AMP-Access-Control-Allow-Source-Origin', 'https://example.com/');
if (fields.first_name && fields.last_name) {
res.setHeader('AMP-Redirect-To', 'https://example.com/some-key');
res.status(200).json(fields);
} else {
res.status(400).json({error: 'Please select a size.'});
}
});
and the second, in amp you can use navigateTo()
<form class="proceed__form" method="post" id="requirements-form"
action-xhr="https://localhost:4040/check-requirements"
target="_top"
on="submit-success:AMP.navigateTo(url='https://google.com')"
>
</form>
OR you can get variable from response
(res.status(200).json({message: 'success', navigateTo: domain + '/profile'});)
<form class="proceed__form" method="post" id="requirements-form"
action-xhr="https://localhost:4040/check-requirements"
target="_top"
on="submit-success:AMP.navigateTo(url=event.response.navigateTo)"
>
</form>

Use code captcha in two forms

I have two forms on a page containing Google captcha code, but only one code works. Does anyone know if you can use the same code with the same key on two forms on the same page?,
Thks,
Yes, you can. But you have to explicitly render the widget as mentioned on the developer guide
you should use something like this on your front end(taken from the developer guide):
<html>
<head>
<title>reCAPTCHA demo: Explicit render for multiple widgets</title>
<script type="text/javascript">
var verifyCallback = function(response) {
alert(response);
};
var widgetId1;
var widgetId2;
var onloadCallback = function() {
// Renders the HTML element with id 'example1' as a reCAPTCHA widget.
// The id of the reCAPTCHA widget is assigned to 'widgetId1'.
widgetId1 = grecaptcha.render('example1', {
'sitekey' : 'your_site_key',
'theme' : 'light'
});
widgetId2 = grecaptcha.render(document.getElementById('example2'), {
'sitekey' : 'your_site_key'
});
grecaptcha.render('example3', {
'sitekey' : 'your_site_key',
'callback' : verifyCallback,
'theme' : 'dark'
});
};
</script>
</head>
<body>
<!-- The g-recaptcha-response string displays in an alert message upon submit. -->
<form action="javascript:alert(grecaptcha.getResponse(widgetId1));">
<div id="example1"></div>
<br>
<input type="submit" value="getResponse">
</form>
<br>
<!-- Resets reCAPTCHA widgetId2 upon submit. -->
<form action="javascript:grecaptcha.reset(widgetId2);">
<div id="example2"></div>
<br>
<input type="submit" value="reset">
</form>
<br>
<!-- POSTs back to the page's URL upon submit with a g-recaptcha-response POST parameter. -->
<form action="?" method="POST">
<div id="example3"></div>
<br>
<input type="submit" value="Submit">
</form>
<script src="https://www.google.com/recaptcha/api.js?onload=onloadCallback&render=explicit"
async defer>
</script>
</body>
</html>
I just wanted a HTML snipped which I can insert multiple times, each time displaying another captcha. Also, I did not want to take care for specific IDs assigned to the containers, which would be very annoying when multiple formulars still appearing on one page will be designed and rendered independently. Here is my solution.
<div class="g-recaptcha"></div>
<script type="text/javascript"><![CDATA[
function renderCaptchas() {
var captchaNodes = document.getElementsByClassName('g-recaptcha');
for (var i = 0; i < captchaNodes.length; i++) {
var captchaNode = captchaNodes[i];
if (!captchaNode.captchaRendered) {
captchaNode.captchaRendered = true;
grecaptcha.render(captchaNode, {"sitekey": "YOUR_SITE_KEY"});
}
}
}
]]></script>
<script src="https://www.google.com/recaptcha/api.js?onload=renderCaptchas&render=explicit" async="async" defer="defer"></script>

How to edit data when combining angularjs and mongodb

I'm a beginner in the AngularJs and MongoDb world (i started learning today!!)
Actually i'm trying to do something very basic : Display a list of record, with an add button and a edit link with each record.
I'm using this lib https://github.com/pkozlowski-opensource/angularjs-mongolab to connect to mongoweb.
Actually my data is displayed, when i try to add a record it works, but the problem is when i try to display the edit form!
Here is my index.html file, in which i display the data with a form to add a record and with the edit links :
<div ng-controller="AppCtrl">
<ul>
<li ng-repeat="team in teams">
{{team.name}}
{{team.description}}
edit
</li>
</ul>
<form ng-submit="addTeam()">
<input type="text" ng-model="team.name" size="30" placeholder="add new team here">
<input type="text" ng-model="team.description" size="30" placeholder="add new team here">
<input class="btn-primary" type="submit" value="add">
</form>
</div>
And here is my edit.html code, which displays an edit form :
<div ng-controller="EditCtrl">
<form ng-submit="editTeam()">
<input type="text" name="name" ng-model="team.name" size="30" placeholder="edit team here">
<input type="text" name="description" ng-model="team.description" size="30" placeholder="edit team here">
<input class="btn-primary" type="submit" value="validate edit">
</form>
</div>
And finally my js code:
var app = angular.module('app', ['mongolabResource']);
app.constant('API_KEY', '____________________________');
app.constant('DB_NAME', 'groups');
app.factory('Teams', function ($mongolabResource) {
return $mongolabResource('teams');
});
app.controller('AppCtrl', function ($scope, Teams) {
$scope.teams = Teams.query();
$scope.addTeam = function() {
varteam = {
name: $scope.team.name,
description: $scope.team.description
};
$scope.teams.push(varteam);
Teams.save($scope.team);
$scope.team.name = '';
$scope.team.description = '';
};
});
app.controller('EditCtrl', function ($scope, Teams) {
//????????
});
My AppCtrl works perfecty, it displays the data w add records perfectly.
Now i want to add the js code for the edit, but i don't even know form where to start ? how do i a get the id parameter in the url ? how do i tell the view to fill out the form fields from the values from the database ? And finally how do i update the databse.
I know that i asked a lot of question but i'm really lost! thank you
There are of course many possible solutions.
One solution is to use angularjs routing. See http://docs.angularjs.org/tutorial/step_07 for a tutorial.
Basically replace your ul list with something like:
<ul>
<li ng-repeat="team in teams">
{{team.name}}
{{team.description}}
edit
</li>
</ul>
Then you can create a route that responde to your url:
yourApp.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/teams', {
templateUrl: 'partials/team-list.html',
controller: 'TeamListCtrl'
}).
when('/teams/:teamId', {
templateUrl: 'partials/team-detail.html',
controller: 'TeamDetailCtrl'
}).
otherwise({
redirectTo: '/teams'
});
}]);
In this way from the detail controller (that will replace your EditCtrl) you can access the id parameter using: $routeParams.teamId
Anyway I suggest to study well all the tutorials for a better overview.

Checking if text area is blank prior to form submission?

So I wrote this code so that every time someone clicks the submit button, a javascript
function, called check, will see if the text area is empty. If it is not, then the form will be submitted.
This is my code. Why isn't it working?
<form method=post name='form_post' id='form_post' action='SUBMITIT.PHP'>
<textarea id=message name=message class=post onfocus=this.className='post_focus';
placeholder='Share your thoughts' maxlength=500></textarea>
<br>
<button onclick='check()' id=button name=button>Post</button>
</form>
<script type="text/javascript">
function check()
{
if(!document.textArea.message.value=="")
{
document.forms["form_post"].submit();
}
}
</script>
Thanks!
EDIT: I finally got it to work. Here's a template if you are having a similar problem.
<!--The form-->
<form action="mypage.php" method="post" name="myForm" id="myForm">
<textarea name=myTextArea id=myTextArea>
</textarea>
</form>
<br>
<button onclick='check()'>
Post
</button>
<!--The script that checks-->
<script type="text/javascript">
function check(){
String.prototype.trim = function() { return this.replace(/^\s+|\s+$/g, ""); };
var textAreaValue=document.getElementById('myTextArea').value;
var trimmedTextAreaValue=textAreaValue.trim();
if(trimmedTextAreaValue!="") {
document.forms["myForm"].submit();
}
}
</script>
The following woks, and it also wipes unnecessary spaces, the form will only submit when given a character
<form action="yourpage.php" method="post" onsubmit="return check(this)">
<textarea id="message"></textarea>
<input type="submit" value="Post" />
</form>
<script>
function check(form){
if (form.message.value.trim() == ""){
return false
}
}
</script>
This is the most simple way to do this, and the advised one.
You could simply add "required" to the textarea field in HTML.
Note: Although the question is quite old, I am adding the answer for the future references.

onsubmit() does not call my function but the form does get submitted

I have a external js file that has the following function in it. It is supped to be called by the forms onsubmit but it doesn't appear to be happening. The form is just submitted without validation. At one point this was working but now it is not. Where am I going wrong? Any help is appreciated.
function validateDelete(form)
{
alert("Validation Started!");
var photoName=form.deleteName;
if (photoName === "")
{
alert("Photo Name Required");
return false;
}
}
<script src="galleryScripts/validation.js" type="text/javascript" ></script>
<form action="galleryScripts/deletePhoto.php?submit=true" name="deleteForm" onsubmit="return validateDelete(this);" id="deleteForm" method="post">
<label>
File Name: <input name="deleteName" type="text" id="deleteName">
</label>
<label>
<input type="submit" name="deleteButton" id="deleteButton" value="Delete" />
</label>
</form>
Make sure that your js is included.
For example under mozilla press CTRL+U and click on a link to your validation.js file.
Also you can just paste in tag in your tag it should work.
