Hello I'm have this idea for a part of the database I'm building but my javascript knowledge is lacking entirely (I'm a software engineering student and we touched on javascript once and I barely remember anything we did).
I have a form where a user is entering the details for a book, title, author, summary etc. What I would like it do it is check and see if the author is all ready in the database, if so nothing happens if not a text box appears in the form for them to enter in the authors biography. I'm fairly certain I need javascript to do this, but I'm entirely new to it and don't know where to start exactly.
Thanks.
