How to get the current view being rendered inside ZF2 - zend-framework2

Question

Is there a way to get the current view being rendered inside zend framework 2?
I believe this should be possible with the event system but I can't seem to make it work.
The reason I want to get this information is so I can automatically include a .js file with the same name, this would save me time having to specify this rule each time i'm inside a action.
Many thanks,
Tom

I'm not quite sure what you mean by rendering the current view inside ZF2, but here's how you can add a js file named after the action automatically. Just put this in your controller:
public function onDispatch(MvcEvent $mvcEvent)
{
$renderer = $this->serviceLocator->get('Zend\View\Renderer\PhpRenderer');
$actionName = $mvcEvent->getRouteMatch()->getParam('action');
$jsFile = $actionName . '.js';
$baseUrl = $mvcEvent->getRouter()->getBaseUrl();
$renderer->headScript()->appendFile($baseUrl . '/js/' . $jsFile);
return parent::onDispatch($mvcEvent);
}
You may need to adjust the code for your js file location and name of course. The onDispatch method is called automatically before the action.

Thank You Wunibald,
Your example worked perfectly, I have modified it below to be attached to an event so that it applies to every controller/module. To do this I have included it into the onBootstrap function in my Application module.
$events = StaticEventManager::getInstance();
$events->attach('Zend\\Mvc\\Application', 'dispatch', function(\Zend\EventManager\Event $event)
{
$baseUrl = $event->getRouter()->getBaseUrl();
$renderer = $event->getApplication()->getServiceManager()->get('Zend\View\Renderer\PhpRenderer');
$action = $event->getRouteMatch()->getParam('action');
$controller = $event->getRouteMatch()->getParam('controller');
if (strlen($controller) > 0)
{
list($module, $_null, $controller) = explode('\\', $controller);
$renderer->headScript()->appendFile($baseUrl . '/module/' . $module . '/view/' . strtolower($module) . '/' . strtolower($controller) . '/' . strtolower($action) . '.js');
$renderer->headScript()->appendFile($baseUrl . '/module/' . $module . '/view/' . strtolower($module) . '/' . strtolower($module) . '.js');
}
});
Once again thank you for pointing me in the right direction.
