Ajax and Jquery in Symfony

You realy just have to replace the targetFile.php by a custom route of yours.

So if you have this in your routing.yml:

# app/config/routing.ymlhello:    pattern:      /ajax/target    defaults:     { _controller: AcmeHelloBundle:Site:index }

You can use this javascript:

$("#div").click(function(){  $.post("/ajax/target",{/*parameters*/,function(data){ });});

On the Symfony2 side, the method indexAction of the SiteController of the AcmeHelloBundle will be called.

If you set inside routing.yml this:

_admin_ajax:    resource: "@SomethingAdminBundle/Controller/AjaxController.php"    type:     annotation    prefix:   /admin/ajax  

... and inside controller, that will handle ajax call this:

/** * @Route("/ajaxhandler", name="_admin_ajax_handler") */public function handlerAction() {        $isAjax = $this->get('Request')->isXMLHttpRequest();    if ($isAjax) {        //...        return new Response('This is ajax response');    }    return new Response('This is not ajax!', 400);}

... then inside for example TWIG template you should call it like this:

$("#div").click(function(){  $.post("{{ url('_admin_items_add') }}",{/*parameters*/,function(data){ });});

... and the real route for your action will be generated with templating engine.
