This was a simple example. But it's actually really easy to return JSON:
public function dispatchLoopShutdown()
{
// assume that we've already determined the request is ajax
$request = $this->getRequest();
$response = $this->getResponse();
$view = Zend_Registry::get('view');
if ($request->getParam('isAjax', false)) {
// Ajax request detected
// Get any variables set in the view
$vars = get_object_vars($view);
// Merge with named path segments in response
$vars = array_merge($vars, $response->getBody(true));
// Create a header and set the response body to a JSON value
$resposne->setHeader('Content-Type', 'text/x-json');
$response->setBody(Zend_Json::encode($vars));
return;
}
// Otherwise, process as normal
$view->content = $response->getBody();
$response->setBody($view->render('site.phtml'));
}
