How to display result in success ajax to twig file

Question

I'm new in Symfony! I use symfony 3. I have a search input when i type in search i want display the result in the twig file. I got the correct result send from ajax and i have a problem with display data result from ajax to twig file and use loop in here. Here is my controller

/**
 * @Route("/ajax_search", name="ajax_search", options={"expose"=true})
 */
public function ajaxSearchAction( Request $request)
{
    $string = $request->get('search_items');
    $users = $this->getDoctrine()
        ->getRepository('AppBundle:Item')
        ->findEntitiesByString($string);

    $encoders = array(new XmlEncoder(), new JsonEncoder());
    $normalizers = array(new GetSetMethodNormalizer());
    $serializer = new Serializer($normalizers, $encoders);

    $jsonContent = $serializer->serialize($users, 'json');
    $response = new Response($jsonContent);

    return $response;
}

ajax :

$(document).ready(function () {
    $("#search_items").keyup(function () {
        var q = $("#search_items").val();
        var url = '../ajax_search?search_items=' + q;
        $.ajax({
            url: url ,
            type: 'POST',
            dataType: 'json',
            data: {q: q},
            success: function(data){
                var result = JSON.stringify(data);
                $('.test').html(result); //return correct data

            }
        });
    });
});

and my twig

<input type="text" name="search" placeholder="search" id="search_items"/>
<div class="test"></div>//i want to get data and use loop in here

In your Action to render the twig template you need to pass your code you want to use in your template as following:

        return $this->render(
        'yourTemplate.html.twig',
        array(
            'yourKey' => callYourFunctionToGetTheData()
        )
    );

In Twig you can address your data like this:

<div>{{ yourKey }}</div>

In Twig are arrays, objects and just "normal" values possible e.g integers,strings and so one.

Hope that this will help you!
