using ajax in a symfony project to delete item

Question

hello I'm looking for a script that could allow me to delete item in a symfony project using ajax, I didn't find any solution for this I tried to delete an item via id (I gave a static id) and then get the result without refreshing the page
here is my controller

$em = $this->getDoctrine()->getManager();

$evenement = $em->getRepository("TunisiaMallBundle:Evenement")->find(39);

$em->remove($evenement);

$em->flush();

$evenements = $em->getRepository("TunisiaMallBundle:Evenement")->findAll();

$response = new Response();

$response->headers->set('Content-Type', 'application/json');

$response->setContent(json_encode($evenements));

return $response;

I didn't know what I'm I supposed to return too.

In your twig put something like this :

<button class="deleteBtn" id="{{ item.id }}">Remove</button>

Here is the ajax using JQuery :

$(document).ready(function(){

$('.deleteBtn').click(function (e) {
    e.preventDefault();

    itemId = $(this).attr('id');

    $.ajax({

        url: frm.attr('action'),
        data: {'entityId':itemId},
        method: 'post',
        success: function (data, reponse) {

         if(reponse == 'good' ){
            //appear pop to say success blabla
         }
        },
        error: function () {
            //appear pop to say error blabla
        },
    });

});

And the Controller :

public function ajaxDeleteItemAction(Request $request)
{

    if($request->isXmlHttpRequest()){
    $id = $request->get('entityId');
    $em = $this->getDoctrine()->getManager();
    $evenement = $em->getRepository("TunisiaMallBundle:Evenement")-
    >find($id);

   $em->remove($evenement);
   $em->flush();


    return new JsonResponse('good');
  }
}
