Breaking: #79196 - Toolbar item event handling changed
|
|
======================================================
|
|
|
|
See :issue:`79196`
|
|
|
|
Description
|
|
===========
|
|
|
|
With the introduction of the topbar reloading mechanism, the event handling of toolbar items has changed. Reason is
|
|
that the event information gets lost, as the whole topbar is rendered from scratch after a reload.
|
|
|
|
|
|
Impact
|
|
======
|
|
|
|
After reloading the topbar, non-migrated events will not get triggered anymore.
|
|
|
|
|
|
Affected Installations
|
|
======================
|
|
|
|
All installations with old-fashioned toolbar item registrations.
|
|
|
|
|
|
Migration
|
|
=========
|
|
|
|
In most cases it's sufficient to replace the register function with :js:`Viewport.Topbar.Toolbar.registerEvent()`.
|
|
|
|
Example:
|
|
|
|
.. code-block:: javascript
|
|
|
|
define(['jquery', 'TYPO3/CMS/Backend/Viewport'], function($, Viewport) {
|
|
// old registration
|
|
MyAwesomeItem.doStuff)
|
|
|
|
// new registration
|
|
Viewport.Topbar.Toolbar.registerEvent(MyAwesomeItem.doStuff);
|
|
});
|
|
|
|
.. index:: Backend, JavaScript
