Calculate Duration from Element width

[robs]

Hi,

 

is it possible to calculate the duration of a tween based on the width of some DOM-Element?

I have something like this:

someTimeline.to(element, {
 width: 0,
 duration: function () { return anotherElement.clientWidth / 290 })
The tween works fine if I put a number to duration. However with the code above the element disappears without animating.

 

Do you have an idea where my mistake is?

 

Thanks so much,

Robert

Happy tweening ...
