any appreciated

i have changed code little bit things more efficiently.

first, used event delegation, means there no need add more listeners during execution. event propagates until reaches form , clicked button identified , event handled.

$('#formcontainer').delegate('button','click',function (e) { ... 

i selected animation , index , there can whatever want.

the form separated rest of page elements, , there 1 form, not 1 form per sprite.

on side note, if myself, separate logical representation of 'back-end' (i.e, code drives animator) ui accompanying creating animator class can instantiated , creates entire interface scratch , reusable , self-contained.

see example here.
