jquery with object oriented javascript

jquery with object oriented javascript

srry this is a repost, but ive dramatically changed my code so the old thread is irreverent and i dont want people to tldr
i had an open/close tab script that worked:
http://patrickallard.net63.net/procedureoriented/
but the code was repetitive and couldnt be expanded for more functionality because i didnt have objects
now i am treating the tabs as objects, and the code is much neater with them:
http://patrickallard.net63.net/
just one problem, it doesnt work! and i have no idea why! could someone please take a look? it is short, well commented and neat and i suppose an experienced person could find the error quickly
you can find the code at the bottom of each page, and ill post it here for convenience sake
tyvm!
