Here is a bit of code that can be used to target specific tinyMCE edtors that I’ve used to detect changes in an editor in order to trigger other events. I don’t know if this will help anyone or not.
jQuery(document).ready(function($){
// add an action to a wysiwyg field
// this function will fire every time a tinyMCE editor is initialized
tinyMCE.on('addEditor', function(e) {
// this makes sure it is an acf editor
if (typeof(e.editor) == 'undefined' || !e.editor.id.match(/^acf-editor/)) {
// not an acf wysiwyg field
return
}
// get the text area of the acf field matching the id
// and make sure that the field key matches the one we want
// to add the action to
var $field_key = $('#'+e.editor.id).closest('.acf-field').data('key');
// see if it is the field key of the field we want to deal with
if ($field_key != 'field_58923ed03766b') {
// not our field
return;
}
// this is the bit that adds a tigger on the input of the editor
var object = $('#'+e.editor.id);
e.editor.on('input', function(ed) {
// trigger the action we want to act on
object.trigger('input');
});
}); // end tinyMCE.on
}); // end ready function
