[TYPO3-mvc] Extbase Backend Ajax Call

Wed Jan 29 13:09:29 CET 2014

Hi,

still working on this issue, and the only solution I found is an  
old-fasioned Backend Extension, but no Extbase Solution?

Here is a nice Ajax Dispatcher:

With some debugging and bugfixing I finally see my Extbase Action  
called in devlog.

Problem: I still have a full HTML page returned on response.

This is the important part of the Code:

public function dispatch() {
         (...)
         $request = $this->buildRequest();
//-> here the call of my Extbase Controller/Action is successful

         $response =  
$this->objectManager->create('Tx_Extbase_MVC_Web_Response');

         $dispatcher =  $this->objectManager->get('Tx_Extbase_MVC_Dispatcher');
         $dispatcher->dispatch($request, $response);
//-> response is a full HTML backend page. It contains the "return  
json_encode($test);" inside <body> tag.

         $response->sendHeaders();
         return $response->getContent();
     }

Currently I think about a starting and finishing string in my return  
value. Then i can get a substring from $response before sending it.  
But thats really ugly... any better ideas?

Best regards,
Andrea
