Breaking: #88667 - Removed additionalJavaScriptSubmit from FormEngine

Description

FormEngine had the feature to add additional submit handlers via the option additionalJavaScriptSubmit, that can be set by form element renderables. TYPO3 uses RequireJS and a rewritten FormEngine since version 7, the property additionalJavaScriptSubmit has been removed.

Additional, functions of TBE_EDITOR that are associated with that feature (namely addActionChecks) were removed as well.

Impact

The option has no effect anymore, the code won't get executed at all.

Affected Installations

All 3rd-party extensions using this option are affected.

Migration

It is possible to create and register an AMD module.

$resultArray['requireJsModules'][] = 'TYPO3/CMS/MyExtension/SubmitHandler';

// typo3conf/ext/my_extension/Resources/Public/JavaScript/SubmitHandler.js
define(['TYPO3/CMS/Backend/DocumentSaveActions'], function (DocumentSaveActions) {
  DocumentSaveActions.getInstance().addPreSubmitCallback(function (e) {
    // e is the submit event
    // Do stuff here

    // e.stopPropagation() stops the execution chain
  });
});
