I've built a form that calls for an editor to be loaded through AJAX, but when I insert the fetched contents I get only a <textarea>. If I hit the toggle editor button, then the editor gets built, but it uses the default configuration for TinyMCE instead of how Joomla tries to configure it.

My Javascript:

}).done(function(response) {


$editor = JFactory::getEditor('tinymce');
echo $editor->display('text', '', 'auto', 'auto', 55, 15, false);

I tried throwing in some Javascript to re-init TinyMCE for this editor, but it also just uses the default configuration instead of what Joomla uses.

After spending more time searching for possibilities, I found that Joomla includes the file /media/editors/tinymce/js/tinymce.min.js, and upon opening the uncompressed version of the file and reading through it, I saw that it has the function Joomla.JoomlaTinyMCE.setupEditors(); which handles the initialization of all instances of TinyMCE on the page.

So, after the AJAX loads the new editor, recalling Joomla.JoomlaTinyMCE.setupEditors(); will handle everything.

  • Well, after going through some of my use cases, I noticed that some config options weren't being set properly unless another editor was already on the page. Trying to resolve now.
