How to simplify a if/else jquery snippet

Question

I have a super long jquery snippet that I feel could be simplified with the right logic. I'm afraid to touch it since I finally got it to work.

the "else $target = #none" is literally a "show nothing" statement. I wasn't sure how to express that in a better way.

Thanks so much! -zeem
