Inserting Links into TinyMCE


I am wanting to have a drop down menu that lists all of the pages that are in the database. When I select a page that I want and click submit, I would like the name of the page as a link to go into the TinyMCE Editor.

I know how to populate a drop-down menu from the database, but how would I then submit it to do into the TinyMCE editor without reloading the page and lose all of the information?
