[jQuery] simple if not :checked then show div - BEGINNER

[tlob]

Hello

I try to do a very simple thing. 7 Checkboxes. 1 submit.
If none checked, show div#none
if not checkbox1:checked show div#not1
and if not checkbox2:checked show div#not2, too
and so on...

I can do it with man if then's, but I like it slick and sexy!
And I cant figure it out.....

Thx in advance
