TinyMCE textarea and post form using ajax
Use this instead of tinymce.triggerSave();
$('#' + 'your_editor_id').html( tinymce.get('your_editor_id').getContent() );
You can configure TinyMCE as follows to keep the values of hidden textareas in sync as changes are made via TinyMCE editors:
tinymce.init({
selector: "textarea",
setup: function (editor) {
editor.on('change', function () {
tinymce.triggerSave();
});
}
});
With this in place, you can access up-to-date values directly from the textarea elements at any time.
This has been tested on TinyMCE 4.0
