Hi Jan,
But still no news regarding extbase in BE :( If anybody has already used
extbase together with ajax in BE, please let me know ;)
The Extension Manager is doing that. Example links are generated as
standard "<a href" links in the template, then are processed by jquery
(main.js):
$('.t3-icon-system-extension-update').parent().each(function() {
$(this).data('href', $(this).attr('href'));
$(this).attr('href', '#');
$(this).addClass('transformed');
$(this).click(function() {
$('.typo3-extension-manager').mask();
$.ajax({
url: $(this).data('href'),
dataType: 'json',
success: updateExtension
});
});
});
dataType: 'json' will ask extbase to use JSON as return type and thus
instruct it to search for a .json template instead of .html.
remove extension is done slightly differently (link comes from the
confirmation dialog) but idea is the same:
if (button == 'yes') {
$('.typo3-extension-manager').mask();
$.ajax({
url: dialog.url,
dataType: 'json',
success: removeExtension
});
}
The controller action does nothing special:
/**
* Remove an extension (if it is still installed, uninstall it first)
*
* @param string $extension
*/
protected function removeExtensionAction($extension) {
$success = TRUE;
$message = '';
try {
if
(\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::isLoaded($extension)) {
$this->installUtility->uninstall($extension);
}
$this->installUtility->removeExtension($extension);
} catch
(\TYPO3\CMS\Extensionmanager\Exception\ExtensionManagerException $e) {
$message = $e->getMessage();
$success = FALSE;
}
$this->view->assign('success', $success)->assign('message',
$message)->assign('extension', $extension);
}
and the corresponding view (RemoveExtension.json) is straightforward:
{namespace em=TYPO3\CMS\Extensionmanager\ViewHelpers}
<em:format.jsonEncode additionalAttributes="{success:success,
message:message, extension:extension}" />
So this is a full example on AJAX call to Extbase in Backend, not using
ExtJS (which is not so beloved anymore) but jQuery.
