Zend框架2：Ajax调用自动禁用布局 [英] Zend Framework 2: Auto disable layout for ajax calls

问题描述

一个Ajax请求我的控制器操作之一目前返回完整的HTML页面。

An AJAX request to one of my controller actions currently returns the full page HTML.

我只希望它返回的HTML（.phtml作为内容），针对该特殊操作。

I only want it to return the HTML (.phtml contents) for that particular action.

以下code不佳手动禁用布局的具体行动解决问题

The following code poorly solves the problem by manually disabling the layout for the particular action:

    $viewModel = new ViewModel();
    $viewModel->setTerminal(true);
    return $viewModel;

我怎样才能让我的应用程序自动禁用布局，检测一个AJAX请求时？我是否需要写这个自定义的策略？如何做到这一点的任何建议是多AP preciated。

How can I make my application automatically disable the layout when an AJAX request is detected? Do I need to write a custom strategy for this? Any advice on how to do this is much appreciated.

此外，我已经试过以下code。在我的应用程序Module.php - 这是正确检测AJAX但setTerminal（）不禁止的布局

Additionally, I've tried the following code in my app Module.php - it is detecting AJAX correctly but the setTerminal() is not disabling the layout.

public function onBootstrap(EventInterface $e)
{
    $application = $e->getApplication();
    $application->getEventManager()->attach('route', array($this, 'setLayout'), 100);

    $this->setApplication($application);

    $this->initPhpSettings($e);
    $this->initSession($e);
    $this->initTranslator($e);
    $this->initAppDi($e);
}

public function setLayout(EventInterface $e)
{
    $request = $e->getRequest();
    $server  = $request->getServer();

    if ($request->isXmlHttpRequest()) {
        $view_model = $e->getViewModel();
        $view_model->setTerminal(true);
    }
}

思考？

推荐答案

事实上，最好的办法是写另一个策略。有一个JsonStrategy它可以自动检测接收头，自动返回JSON格式的，但与阿贾克斯，呼吁fullpages，有它的好，它并不会自动做的事情，因为你可能希望得到一个完整的页面。上面提到的解决方案，您提到的将是快速的路要走。

Indeed the best thing would be to write another Strategy. There is a JsonStrategy which can auto-detect the accept header to automatically return Json-Format, but as with Ajax-Calls for fullpages, there it's good that it doesn't automatically do things, because you MAY want to get a full page. Above mentioned solution you mentioned would be the quick way to go.

当去为全速，你只能有一个附加行。它总是从你的控制器内返回完全合格的ViewModels最佳实践。像：

When going for full speed, you'd only have one additional line. It's a best practice to always return fully qualified ViewModels from within your controller. Like:

public function indexAction() 
{
    $request   = $this->getRequest();
    $viewModel = new ViewModel();
    $viewModel->setTemplate('module/controller/action');
    $viewModel->setTerminal($request->isXmlHttpRequest());

    return $viewModel->setVariables(array(
         //list of vars
    ));
}
