A bit of background:

  1. On bootstrap, I'm using jQuery's .data() to store a (paused) TweenLite object against an associated DOM element - there are 10 of these such elements.
  2. I'm then iterating through these DOM elements, and appending a cloned TweenLite object to an array.

The reason I need to clone (using jQuery.extend()) each TweenLite object is because I don't wish to use the reference-based relationship that .data() uses; I simply want a clone of the object.


However, when I try this, I get an uncaught exception thrown, Cannot add [object Object] into the timeline; it is not a tween, timeline, function, or string. How can I get around this?


My codepen is

Thanks for any help in advance

Sounds like the 'clone' isn't a true clone, so GSAP doesn't understand what you're passing it. Clones of anything other than primitives are rather tricky in javascript - I'm not sure how easy it's going to be to get this to work.


Have you considered just saving the target, duration, and vars object in data(), and instantiating a new tween with those values when you need it? I imagine it would be much simpler than trying to get cloning to work.
