How can I stop the rendering of the layout when sending a request via AJAX .. The problem I am facing is the json data reflected in the browser, and not passed to the jquery functions
here my script
jQuery.ajax({
url: "/getPrivileges",
type: "POST",
dataType: 'JSON',
success: function(privileges){
alert('hellooo');
buildTree(privileges,".privBox h2");
if($(".privPrivilege"))
$("#loading").css("visibility","hidden");
},
error: function (request, status, error) {
alert('Error'+request.responseText);
}
});
and here routing
resources.router.routes.privilege.route = /getPrivileges
resources.router.routes.privilege.defaults.module = privileges
resources.router.routes.privilege.defaults.controller = privilege
resources.router.routes.privilege.defaults.action = get-privileges
and here is my controller
public function getPrivilegesAction() {
if ($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);
}
}
At first, I am faced with the fact that the layout is still displayed, but now json is printed on the screen, even I do not have the get-privileges.phtml access page.
and in the controller's init () method, I do it like
public function init() {
$ajaxContextSwitch = Zend_Controller_Action_HelperBroker::getStaticHelper('AjaxContext');
$ajaxContextSwitch->setDefaultContext('json');
$ajaxContextSwitch->addActionContext('getPrivileges', 'json');
$ajaxContextSwitch->initContext();
}
how can i answer by responding to jquery callback function! It is important to note that not all URLs have custom routes.
please help, because I am almost leaving development using the Zend framework !!
