Hi,
I wonder if there is a way to trigger a js function once an animation is done ?
Thanks in advance

Animator pro allows you to add or remove classes after the conclusion of an animation. I don’t know much about javascript, but I believe you can trigger a js event when a class is added or removed.

Has all kinds of ‘do this’ ‘to that’ ‘on event’ handlers and could probably do what you want, and more.
