如何停止渲染爾康模板使用Ajax時？

Question

我在我的Phalcon項目中使用了很多Ajax，並且每個請求都由特定的控制器/動作處理，其中我禁用了模板呈現（僅呈現視圖）。

我怎麼能全局禁用模板時，如果呼叫使用Ajax做？

Answer 1

對於一個具體的行動，你可以使用這些實現的：

public function saveAction() 
{ 
    $this->view->disable(); 

    // Operations go here..... 

    $this->view->pick('some/view/to/display'); 
} 

public function resetAction() 
{ 
    $this->view->disable(); 

    // Operations go here..... 

    echo 'reset action' 
} 

public function cancelAction() 
{ 
    $this->view->disable(); 

    // Operations go here..... 
    $response = new \Phalcon\Http\Response(); 
    $response->setStatusCode(200, 'OK'); 
    $response->setContentType('application/json', 'UTF-8'); 
    $response->setJsonContent('some content goes here', JSON_UNESCAPED_SLASHES); 

    return $response->send(); 
}

我找到了答案:)

abstract class ControllerBase extends Controller 
{ 
    /** 
    * Called in each Controller/Action request 
    */ 
    public function initialize(){ 
     if($this->request->isAjax()){ 
      $this->view->setRenderLevel(View::LEVEL_ACTION_VIEW); 
     } 

    ...

可用的渲染級別是：

 
Class Constant   Description Order 
LEVEL_NO_RENDER   Indicates to avoid generating any kind of presentation. 
LEVEL_ACTION_VIEW  Generates the presentation to the view associated to the action. 1 
LEVEL_BEFORE_TEMPLATE Generates presentation templates prior to the controller layout. 2 
LEVEL_LAYOUT   Generates the presentation to the controller layout. 3 
LEVEL_AFTER_TEMPLATE Generates the presentation to the templates after the controller layout. 4 
LEVEL_MAIN_LAYOUT  Generates the presentation to the main layout. File views/index.phtml 5
