Data variable in vue.js is not appears in the view when populated by ajax request

I have the code below, the 'tarefas' variable is not appear in my v-for, and I verify the response from the server and its ok, the data are coming. When I add new data in the input field, it works correctly
JS:
var app = new Vue({
el: '#app',
data: {
titulo: 'Lista de Tarefas',
tarefas: [],
tarefa: ''
},
methods: {
addTarefa: function () {
console.log(this.tarefa);
if (this.tarefa !== '') {
this.tarefas.push({identificador: 0, descricao: this.tarefa, feito: 0});
this.postTasks();
//this.tarefa = '';
}
},
removerTarefa: function (tarefa) {
this.tarefas.splice(this.tarefas.indexOf(tarefa), 1)
},
syncTasks: function () {
jQuery.get('http://localhost:51622/api/tarefa', function (data, status) {
this.tarefas = data;
console.log(data);
console.log(this.tarefas);
});
},
postTasks: function () {
jQuery.post('http://localhost:51622/api/tarefa', {identificador: 0, descricao: this.tarefa, feito: 0});
},
},
created: function () {
console.log("passei no mounted");
this.syncTasks();
},});
HTML:
<p class="text-primary center">{{ titulo }}</p>
<div class="col-xs-3">
<input type="text" placeholder="digite a tarefa" v-model="tarefa" class="form-control" />
</div>
<button v-on:click="addTarefa" class="btn btn-default">add tarefa</button>
<br />
<br />
<div class="col-xs-3">
<ul class="list-group">
<li v-for="tarefa in tarefas" class="list-group-item">{{ tarefa }} <button class="btn" v-on:click="removerTarefa(tarefa)">X</button></li>
</ul>
</div>
</div>
</div>
<script src="app.js"></script>

Since your callback is a regular function, your this is not pointing to the Vue. Try an arrow function.
jQuery.get('http://localhost:51622/api/tarefa', (data, status) => {
this.tarefas = data;
console.log(data);
console.log(this.tarefas)
});

ng-click(parameters) open a popup window with dropdown,then selected item and parameters sent to the service

I'm new to Angular-js. I'm using JSP for front end and passing values from UI to controller.Now I need to open a new popup list where user can select an option, then pass all parameters to service ..
ng-click="rewardRetry(singleWinner)"
controller --->
$scope.retryRewardDTO = {
"mobile_number" : null,
"draw_id" : 0,
"lottery_ticket_id" : 0,
"prize" : 0,
"reward_method" :null
};
(mobile_number,draw_id,lottery_ticket_id,prize) I can assign like this
$scope.rewardRetry = rewardRetry;
function rewardRetry(rewardRetryDTO) {
$scope.retryRewardDTO.draw_id=rewardRetryDTO.draw_id;
$scope.retryRewardDTO.lottery_ticket_id=rewardRetryDTO.lottery_ticket_id;
$scope.retryRewardDTO.prize=rewardRetryDTO.prize;
$scope.retryRewardDTO.mobile_number=rewardRetryDTO.mobile_number;
//$scope.retryRewardDTO.reward_method=rewardRetryDTO.reward_method;
}
But here retryRewardDTO.reward_method -->user should be select in popup option. (wallet,m_cash,reload,,, ....etc)
calling to service
winnerService.winnerService.rewardRetry(
$scope.retryRewardDTO,
function(data, headers) {
winnerSearch();
}, function() {
});
I'm trying do something like below link.but couldn't get a proper output.please some helps to me...
visit :AngularJS Modal Popup

Finally I found the answer and here implemented new rewardService
$scope.rewardRetry = rewardRetry;
function rewardRetry(rewardRetryDTO) {
$scope.retryRewardDTO.draw_id=rewardRetryDTO.draw_id;
$scope.retryRewardDTO.lottery_ticket_id=rewardRetryDTO.lottery_ticket_id;
$scope.retryRewardDTO.prize=rewardRetryDTO.prize;
$scope.retryRewardDTO.mobile_number=rewardRetryDTO.mobile_number;
//$scope.retryRewardDTO.reward_method=rewardRetryDTO.reward_method;
var modalOptions = {
bodyText : 'Are you sure you want to retry '+$scope.retryRewardDTO.prize+'/= reward for 0'+ $scope.retryRewardDTO.mobile_number+' ? Please select a reward method first and confirm'
};
rewardService.showModal({}, modalOptions).then(
function(result) {
$scope.retryRewardDTO.reward_method = result;
$('#retry-'+rewardRetryDTO.draw_id+'-'+rewardRetryDTO.lottery_ticket_id).hide();
$timeout(function() {
winnerService.winnerService.rewardRetry(
$scope.retryRewardDTO,
function(data, headers) {
winnerSearch();
}, function() {
});
});
});

Symfony2: manually submit a form without class via AJAX

We have an old website where I have implemented a form that is sent by AngularJS to a PHP script and after processing an email message get sent. If the form is not valid the PHP script returns a JSON with the validation errors. Since we already use Symfony for some other applications (REST APIs), I thought it would be nice to reimplement my plain PHP script in Symfony.
For the sake of simplicity I put only a small but relevant fragment of my code. This is what I have:
HTML (ng-app is bound on body tag, not shown here):
<form name="infoscreenForm" class="form-horizontal" enctype="multipart/form-data" ng-controller="FormController">
<div class="form-group">
<div class="col-lg-1 control-label">*</div>
<div class="col-lg-11 input-group">
<input type="text" class="form-control" id="contact_person"
name="contact_person" ng-model="formData.contactPerson"
placeholder="Kontaktperson">
</div>
<span class="text-warning" ng-show="errors.contactPerson">
{{ errors.contactPerson }}
</span>
</div>
<div class="form-group">
<div class="col-lg-1 control-label">*</div>
<div class="col-lg-11 input-group">
<span class="input-group-addon">#</span>
<input type="email" class="form-control" id="email" name="email"
ng-model="formData.email" placeholder="E-Mail">
</div>
<span class="text-warning" ng-show="errors.email">
{{ errors.email }}
</span>
</div>
<div class="form-group">
<div class="col-lg-1 control-label"> </div>
<div class="col-lg-11 input-group">
<input type="file" class="form-control" id="file" name="file"
file-model="formData.file"
accept="application/pdf,image/jpeg,image/png">
</div>
<span class="text-warning" ng-show="errors.file">
{{ errors.file }}
</span>
</div>
<div class="form-group">
<button type="submit" class="btn btn-default" id="submit"
name="submit" ng-click="submitForm()">
Formular absenden
</button>
</div>
</form>
JS:
var app = angular.module('InfoscreenApp', []);
app.directive('fileModel', ['$parse', function ($parse) {
return {
restrict: 'A',
link: function (scope, element, attrs) {
var model = $parse(attrs.fileModel);
var modelSetter = model.assign;
element.bind('change', function () {
scope.$apply(function () {
modelSetter(scope, element[0].files[0]);
});
});
}
};
}]);
app.factory('multipartForm', ['$http', function ($http) {
return {
post : function (uploadUrl, data) {
var fd = new FormData();
for (var key in data) {
fd.append(key, data[key]);
}
return $http.post(uploadUrl, fd, {
transformRequest: angular.identity,
headers : { 'Content-Type': undefined }
});
}
};
}]);
app.controller('FormController', ['$scope', 'multipartForm', function ($scope, multipartForm) {
$scope.formData = {};
$scope.submitForm = function () {
var uploadUrl = 'http://localhost:8000/infoscreen';
multipartForm.post(uploadUrl, $scope.formData)
.then(function (data) {
console.log(data);
if (data.success) {
$scope.message = data.data.message;
console.log(data.data.message);
} else {
$scope.errors = data.data.errors;
}
});
};
}]);
With the plain PHP script everything works fine. Here is what I tried to do in Symfony:
<?php
namespace AppBundle\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
use Symfony\Component\Form\Extension\Core\Type\FileType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\Validator\Constraints\NotBlank;
use Symfony\Component\Validator\Constraints\Email;
class DefaultController extends Controller
{
/**
* #Route("/infoscreen", name="infoscreen")
*/
public function infoscreenAction(Request $request)
{
$defaultData = array('message' => 'infoscreenForm');
$form = $this->createFormBuilder($defaultData)
->add('contactPerson', TextType::class, array(
'constraints' => array(
new NotBlank(),
)
))
->add('email', EmailType::class, array(
'constraints' => array(
new NotBlank(),
new Email(),
)
))
->add('file', FileType::class)
->add('submit', SubmitType::class)
->getForm();
;
$form->submit($request->request->get($form->getName()));
$data = $form->getData();
if ($form->isValid()) {
echo 'Alles ok';
// send an email
}
$errors = array();
$validation = $this->get('validator')->validate($form);
foreach ($validation as $error) {
$errors[$error->getPropertyPath()] = $error->getMessage();
}
$response = new Response();
$response->setContent(json_encode(array(
'form_data' => $data,
'errors' => $errors,
)));
$response->headers->set('Content-Type', 'application/json');
return $response;
}
}
CSRF is disabled in config.yml. The form is not bound to an entity class. After submitting the form I get the following object in the console:
{
data: Object,
status: 200,
config: Object,
statusText: "OK"
}
The important part is in data: Object:
{
form_data: {
contactPerson: null,
email: null,
message: "infoscreenForm",
file: null
},
errors : {
children[contactPerson].data = "This value should not be blank",
children[email].data = "This value should not be blank"
}
}
This happens when I submit the form with some values entered in the fields. It seems that the submitted data is not bound to the form in the controller. I'm probably missing something, but I stuck here and have no idea how to proceed. I tried with $form->bind($request), $form->handleRequest($request) and few other things, but it didn't work. Even if I bind the fields individually, I still don't get their values in the form.
Can somebody please help me.
Thanks in advance.

Try
$this->get('form.factory')->createNamedBuilder(null, 'form', $defaultData)
instead of
$this->createFormBuilder($defaultData)

SilverStripe submit HTML form through Ajax

I want to pass data from a simple HTML form to a controller through Ajax, then process the data and return a response back.
At the moment I have the following:
HomePage.ss
<form method="POST" class="form-horizontal submit-form" onsubmit="return checkform(this);">
<!-- Text input-->
<div class="form-group">
<label class="col-md-4 control-label" for="name">Name</label>
<div class="col-md-8">
<input id="name" name="name" type="text" placeholder="insert full Name" class="form-control input-md" required="" />
</div>
</div>
<!-- Button -->
<div class="form-group">
<label class="col-md-4 control-label" for="send-btn"></label>
<div class="col-md-8">
<button id="send-btn" name="send-btn" class="btn btn-primary">Submit</button>
</div>
</div>
</form>
JavaScript
$('form.submit-form').submit(function() {
$.ajax({
type: 'POST',
url: 'processForm',
data: $(this).serialize(),
success: function(data) {
alert('data received');
}
});
});
HomePage.php
class HomePage_Controller extends Page_Controller {
public function events() {
$events = CalendarEvent::get();
return $events;
}
public function processForm() {
if (Director::is_ajax()) {
echo 'ajax received';
} else {
//return $this->httpError(404);
return 'not ajax';
}
}
}
In developer tools I can see that I got the xhr processForm with a 404 not found error.
How do I get this Ajax form working correctly with the SilverStripe controller?

Spider,
I've done something similar to below. This is a quick and dirty demo and hasn't been tested, but it may get you going in the right path. If you're unfamiliar with how forms work within SilverStripe there is a lesson for front end forms in SilverStripe. I've found the lessons useful personally and provide the code for the lesson as well: http://www.silverstripe.org/learn/lessons/introduction-to-frontend-forms?ref=hub
Page.php
<?php
class Page extends SiteTree
{
}
class Page_Controller extends Content_Controller
{
private static $allowed_actions = array(
'MyForm',
);
public function MyForm()
{
Requirements::javascript(THIRDPARTY_DIR . '/jquery/jquery.min.js');
Requirements::javascript(THIRDPARTY_DIR . '/jquery-validate/jquery.validate.min.js');
Requirements::javascript('/path/to/your/validation/script.js');
$fields = FieldList::create(
TextField::create('name')
->setTitle('Name')
);
$actions = FieldList::create(
FormAction::create('doSubmit')
->setTitle('Submit')
);
$requiredFields = RequiredFields::create(
'name'
);
$form = Form::create($this, 'MyForm', $fields, $actions, $requiredFields);
return $form;
}
public function doSubmit($data, $form)
{
//process $data or create your new object and simpley $form->saveInto($yourObject); then $yourObject->write()
//then deal with ajax stuff
if ($this->request->isAjax()) {
return $this->customise(array(
'YourTemplateVar' => 'Your Value'
))->renderWith('YourIncludeFile');
} else {
//this would be if it wasn't an ajax request, generally a redirect to success/failure page
}
}
}
YourValidationScript.js
(function ($) {
$(function () {
$('#MyForm_Form').validate({
submitHandler: function (form) {
$.ajax({
type: $(form).attr('method'),
url: $(form).attr('action') + "?isAjax=1",
data: $(form).serialize()
})
.done(function (response) {
$('.content').html(response);
})
.fail(function (xhr) {
alert('Error: ' + xhr.responseText);
});
},
rules: {
name: "required"
}
});
})
})(jQuery);

You need to understand how HTTP request routing is handled in SilverStripe.
When you send request POST /processForm, it is treated as page and managed by ModelAsController. That is why you get 404 error - there is no SiteTree record with URLSegment = processForm.
Solution 1
Use Form object. It creates all routing configuration automatically during runtime. Read more
https://docs.silverstripe.org/en/3.3/tutorials/forms/
https://docs.silverstripe.org/en/3.3/developer_guides/forms/
Solution 2
Use this approach, when you really want to go down to the simple one method request handler. Register custom controller and routing.
You specify your route in mysite/_config/routing.yml
---
Name: siteroutes
---
Director:
rules:
processCustomForm: CustomFormController
Handle your request
class CustomFormController extends Controller
{
public function handleRequest( SS_HTTPRequest $request, DataModel $model ) {
if (!$request->isPost()) {
// handle invalid request
}
$name = $request->postVar('name')
// process your form
}
}

Edit MEANJS list in the list page

I am using MEAN JS, i am trying to edit the list items on the list page, but it shows the error as below. i have initiated the data using ng-init="find()" for the list and ng-init="findOne()" for individual data.
Error: [$resource:badcfg] Error in resource configuration for action `get`. Expected response to contain an object but got an array
HTML
Below i the form inside the controller where it initiates the find() and findOne().
<div ng-controller="OrdersController" ng-init="find()">
<div>
<div class="order-filter">
<div ng-repeat="order in orders">
<form ng-init="findOne()" name="orderForm" class="form-horizontal" ng-submit="update(orderForm.$valid)" novalidate>
<input type="text" class="" ng-model="order.title">
<input type="text" class="" ng-model="order.content">
<div class="form-group">
<input type="submit" value="Update" class="btn btn-default">
</div>
</form>
</div>
</div>
</div>
</div>
Controller
$scope.update = function (isValid) {
$scope.error = null;
if (!isValid) {
$scope.$broadcast('show-errors-check-validity', 'orderForm');
return false;
}
var order = $scope.order;
order.$update(function () {
$location.path('orders/' + order._id);
}, function (errorResponse) {
$scope.error = errorResponse.data.message;
});
};
$scope.find = function () {
Orders.query(function loadedOrders(orders) {
orders.forEach(appendFood);
$scope.orders = orders;
});
};
$scope.findOne = function () {
$scope.order = Orders.get({
orderId: $stateParams.orderId
});
};

You need to check your Orders Service which probably is using $resource to provide your API requests (Orders.query)
It should look something like this:
function OrdersService($resource) {
return $resource('api/orders/:orderId', {
orderId: '#_id'
}, {
update: {
method: 'PUT'
}
});
}
The style may be different depending on which version of mean you're using. By default, the $resource query will expect an array of results, but if for some reason you've set "isArray" to false then it will expect an object.
