Question

How can I stop Layout rendering, when sending request through AJAX..
The problem I face is json data is echoed on the browser, not passed to tha call back function of jquery

here’s my script

jQuery.ajax({
    url: "/getPrivileges",
    type: "POST",
    dataType: 'JSON',
    success: function(privileges){
        alert('hellooo');

        buildTree(privileges,".privBox h2");
        if($(".privPrivilege"))
            $("#loading").css("visibility","hidden");
    },
    error: function (request, status, error) {
        alert('Error'+request.responseText);
    }

});

and here’s the routing

resources.router.routes.privilege.route = /getPrivileges
resources.router.routes.privilege.defaults.module = privileges
resources.router.routes.privilege.defaults.controller = privilege
resources.router.routes.privilege.defaults.action = get-privileges

and here’s my controller

  public function getPrivilegesAction() {

        if ($this->getRequest()->isXmlHttpRequest()) {
         ...........
         ...........
          $this->_helper->json($appPrivArray);
          $this->_helper->viewRenderer->setNoRender(TRUE);
          $this->_helper->layout->disableLayout();
          $response = $this->getResponse();
          $response->setHeader('Content-type', 'application/json', true);
   }


 }

First I face that layout still rendered but now the json is printed on the screen, even I don’t have get-privileges.phtml view page.

and in the init() method of the controller, I make like this

 public function init() {
    $ajaxContextSwitch = Zend_Controller_Action_HelperBroker::getStaticHelper('AjaxContext');
    $ajaxContextSwitch->setDefaultContext('json');
    $ajaxContextSwitch->addActionContext('getPrivileges', 'json');
    $ajaxContextSwitch->initContext();
}

how can I make response deliver to the call back function of jquery!
It’s important to mention that not all urls has custom routes..

please help, because I almost will retire from development using Zend framework !!

In the action, you just need to use

$this->_helper->json($appPrivArray)

You do not need to use setNoRender or anything else.
And in the Javascript you do not need to use dataType: 'JSON',
I tested this, should work fine.
