Joomla 3 JQuery json response

[Mind gem]

Hello,

I'm trying to customize a certain component to use JSON and the system-message-container to get the response. Resources I tried to follow are:

http://joomlablog.ru/dokumentatsiya/dlya-razrabotchika/api/542-jresponsejson-vozvrashchaem-dannye-v-formate-json

And

https://docs.joomla.org/JSON_Responses_with_JResponseJson

But I cant get it to work.

My scripts:

jQuery(function($) {

$(document).ready(function() {

$('button.submit').on('click', function(){
$('#vote-form').submit();
return false;
});

$('#vote-form').submit(function(event) {

var domForm = document.getElementById('vote-form');

if (!document.formvalidator.isValid(domForm)) {

return false;

}

console.log(url);

$.getJSON(index.php?option=com_polls&task=poll.vote&format=json', {data: data})
.done(function(r) {
if (!r.success && r.message)
{
alert(r.message);
}
if (r.messages)
{
Joomla.renderMessages(r.messages);
}
if (r.data)
{
alert(r.data.myfirstcustomparam);
alert(r.data.mysecondcustomparam);
}
})
.fail(function() {
alert('Ошибка Ajax запроса!');
})
.always(function() {
alert('Ajax запрос завершен');
});




return false;

});

});
});

My controller part:

public function vote() {

JSession::checkToken() or jexit(JText::_('JINVALID_TOKEN'));

$app = JFactory::getApplication();
$model = $this->getModel('poll');
$params = JComponentHelper::getParams('com_polls');
$user = JFactory::getUser();
$id = $app->input->getInt('poll_id', 0);

$app->enqueueMessage('Some error message', 'warning');
$result = true;
echo new JResponseJson($result, 'blbblbl');
jexit();

}

This echo's the json response in a reloaded blank page. The console.log gives me the right expected url.

Anyone could point me in the right direction?

these two parts is the cause of your problem,

At AJAX request you do not send the token, but you tries to check the in your controller,

actually there some more undefined variables in your JavaScript code

I commented out the lines before the jresponsejson which aren't needed at the moment (off course not the $app). But still the same problem.

What you mean by "actually there some more undefined variables in your JavaScript code"? Which ones that are relevent for this test and could make it echo on blank page?

example I do not see where defined: data in {data: data} and "url" in console.log(url); 

check you browser console for more details

the data var isn't required for the getJSON? I thought it was the form data.

I will check later this day if that makes a difference and let know.

Thnx!

Hello,

[Allon Moritz]

I needed it for my attachments extension. To send the message I use the following code https://github.com/Digital-Peak/DPAttachments/blob/master/com_dpattachments/admin/helpers/dpattachments.php#L61. On the javascript side I do a jQuery.ajax call (you have much more configuration options).

I looked at your upload script in dp but only could find a minifed js? Do you have a readable example of the ajax js you use?

Hello,

So I've got the getjson part working now. Does anyone have an example of how I give setRedirect from my controller to javascript and redirect my page after jresponsejson gave a success back?

In javascript do document.location.href = 'new url';
