The content area of RadEditor is an editable IFRAME, which is another document which has not access to the parent page where the jQuery scripts resides. If you are able to implement the required functionality using an editable IFRAME element (as the one included in the attached HTML file) you will be able to implement it in RadEditor.
Please, note also that RadEditor automatically strips the <script> tags and you should disable the RemoveScripts filter
. You also need to import reference to the jQuery script files in the HTML loaded in the content area.
