TYPO3:如何通过控制器初始化动作和页面渲染器添加CSS和JS文件?

问题描述：

我正在使用TYPO3 8在控制器级别上的新页面渲染器，通过initializeAction添加特定于扩展名的css和js文件:

I am using the new page renderer from TYPO3 8 on controller level to add extension specific css and js files via an initializeAction:

public function initializeAction()
{
    $extPath = ExtensionManagementUtility::siteRelPath(
        $this->request->getControllerExtensionKey()
    );

    $extJs = $extPath . 'Resources/Public/Js/ext_booking_manager.min.js';
    $extCss = $extPath . 'Resources/Public/Css/ext_booking_manager.css';

    /** @var PageRenderer $pageRenderer */
    $pageRenderer = $this->objectManager->get(PageRenderer::class);

    $pageRenderer->addCssFile($extCss);
    $pageRenderer->addJsFooterFile(
        $extJs, 'text/javascript', false
    );
}

这有时可以正常工作，但仅在某些情况下可以.这意味着有时会正确添加css文件和js文件，有时如果我重新加载页面，则将不会正确添加文件.有什么问题吗?

This is working fine sometimes, but only sometimes. This means that sometimes the css file and js file will be properly added and sometimes if I reload the page then the files will not be added properly. Is there something wrong?

对于像TYPO3 7这样的旧版本，我使用了类似的东西:

For older versions like TYPO3 7, I used something similar like this:

public function initializeAction()
{
    $extPath = ExtensionManagementUtility::siteRelPath(
        $this->request->getControllerExtensionKey()
    );

    $extJs = $extPath . 'Resources/Public/Js/ext_booking_manager.min.js';
    $GLOBALS['TSFE']->getPageRenderer()->addJsFooterFile(
        $extJs, 'text/javascript', false
    );

    parent::initializeAction();
}

但是，这将不再适用于TYPO3 8.有什么建议吗?

But this will not work for TYPO3 8 anymore. Any suggestions?

答

请注意，TYPO3 v8中使用

Notice that there is a different approach available in TYPO3 v8 using the HeaderAssets and FooterAssets sections in your template. Thus your action template could look like this:

Your template code

<f:section name="FooterAssets">
  <link rel="stylesheet" href="{f:uri.resource(path: 'Css/ext_booking_manager.css')}"/>
  <script src="{f:uri.resource(path: 'Js/ext_booking_manager.min.js')}"></script>
</f:section>

这样，您的控制器不需要任何资源逻辑，因此可以删除initializeAction()方法.

This way you don't need any resource logic in your controller, thus your initializeAction() method can be dropped.

顺便说一句:我建议使用JavaScript作为JavaScript资源的目录名称，以与TYPO3约定保持一致.

BTW: I'd recommend using JavaScript as directory name for JavaScript resources to stay in line with TYPO3 conventions.
