[TYPO3-mvc] Extbase Backend Ajax Call

Tue Jan 21 14:45:53 CET 2014

Hello,

how can I create a ajax call in TYPO3 Backend using Extbase?
In Frontend, I usually configure typeNum for Ajax rendering, but I  
have no idea how to do that in a Backend Module.
With this code, I get a successful Ajax return, but its content is a  
complete HTML Page returned with <head> and everything.
Important: needs to be running on TYPO3 Version 4.5

Controller:

class Tx_Test_Controller_TestController extends  
Tx_Extbase_MVC_Controller_ActionController {

     public function testAjaxAction() {
          $test = array('test'=>1, 'test2'=>2);
          return json_encode($test);
     }
}

Fluid:

<script type="text/javascript">
   Ext.Ajax.request({
     url: '<f:uri.action action="testAjax" />',
     timeout: 60000,
     method: 'GET',
     scope: this,
     params: '',
     success: function(resp) {
         console.log(resp);
     },

});

Thanks for any advice!
Andrea
