Animation length of other object

I need to find the animation length of an animation which is attached to a different object.

First I play the animation:


After this line I want to yield WaitForSeconds(animation.length). But how? I tried:

var length = GameObject.Find("myObject").animation.length("jump");

Check the documentation.

Animation doesn’t have a length function, but an AnimationClip has a length variable, as does an AnimationState
