AJAX in TYPO3 – Glossary

TYPO3 AJAX

AJAX (Asynchronous JavaScript and XML) is a technique used to create faster and more interactive web applications. When working with TYPO3, AJAX can make your website more dynamic without reloading the entire page.

Here is a simple guide to get started with TYPO3 AJAX:

1. Basic TYPO3 AJAX setup:

   Make sure TYPO3 is installed and running. Use JavaScript to send requests to the server without refreshing the page.

2. Create an AJAX request:

   Use JavaScript (or jQuery) to send an AJAX request.

   Example in jQuery:

   $.ajax({
      url: 'your-ajax-endpoint',
      type: 'POST',
      data: { key: 'value' },
      success: function(response) {
          // Handle the response
          console.log(response);
      }
   });

3. Processing the request in TYPO3:

   Create a PHP script in your TYPO3 installation to handle the AJAX request.Register this script as an AJAX endpoint in TYPO3.

4. Register the AJAX endpoint:

   Register the AJAX endpoint in your TYPO3 extension in the ext_localconf.php file:

   \TYPO3\CMS\Extbase\Utility\ExtensionUtility::configurePlugin(
      'Vendor.Extension',
      'PluginName',
      [
          'Controller' => 'action'
      ],
      [
          'Controller' => 'action'
      ],
      \TYPO3\CMS\Extbase\Utility\ExtensionUtility::PLUGIN_TYPE_PLUGIN
   );

5. Return data to JavaScript:

   Your PHP script should process the request and return the required data.Make sure the response is in a format that JavaScript can handle, like JSON.By using AJAX in TYPO3, you can create a smoother user experience with faster interactions. Have fun programming!

AJAX allows a page to reload data in the background without reloading completely. In TYPO3 it is used for live search, filter lists, “load more” buttons, forms with instant feedback or dynamic map views. For visitors the page feels faster and smoother.

Technically, JavaScript sends a request to an interface that returns data or ready-made HTML. In TYPO3, middleware, Extbase actions or custom routes are available for this. You should pay attention to security: validate inputs, check permissions and use CSRF protection.

For accessibility and search engines, dynamic content is a challenge. Reloaded areas must be announced to screen readers, and important content should also be reachable without JavaScript. The browser back button and unique URLs should work as well.

Modern alternatives such as the Fetch API replace the old XMLHttpRequest, but the principle stays the same. We help you implement interactive features so that they are fast, secure and accessible.
