Question

My Zend controller is like below:

 public function deleteAction()
    {
        $this->_helper->layout->disableLayout();
         $id = (int)$this->_request->getPost('id');
        $costs = new Application_Model_DbTable_Costs();
        if($costs->deleteCosts($id)){
            $this->view->success = "deleted";
        }

    }

And ajax call I ma using to post data is :

 $.ajax({
             dataType: 'json',
            url: 'index/delete',
            type: 'POST',
            data:id,
            success: function () {
             alert("success");
            },

            timeout: 13*60*1000,
            error: function(){
               console.log("Error");
            }

        });

And in my delete.phtml the code is like:

<?php 
    if($this->delete === true): 
        echo 'true';
    else:
        echo 'Sorry! we couldn\'t remove the source. Please try again.';
    endif;
?>

The response is returning the html.

Its my first project with Zend Framework.
Thanks in advance.

Your controller action is returning HTML, not JSON.

You should consider using the AjaxContext action helper

public function init()
{
    $this->_helper->ajaxContext->addActionContext('delete', 'json')
                               ->initContext();
}

public function deleteAction()
{
    $id = (int)$this->_request->getPost('id');
    $costs = new Application_Model_DbTable_Costs();
    try {
        $costs->deleteCosts($id));
        $this->view->success = "deleted";
    } catch (Exception $ex) {
        $this->view->error = $ex->getMessage();
    }    
}

The only other thing you need to do here is supply a format parameter of json in the AJAX request, eg

$.post('index/delete', { "id": id, "format": "json" }, function(data) {
    if (data.error) alert("Error: " + data.error);
    if (data.success) alert("Success: " + data.success);
}, "json");

You may want to handle the response differently but that should give you an idea.
