Kills all the tweens (or specific tweening properties) of a particular object or the delayedCalls to a particular function. If, for example, you want to kill all tweens of elements with the class "myClass", you'd do this:


To kill only particular tweening properties of the object, use the second parameter. For example, if you only want to kill all the tweens of myObject.opacity and myObject.x, you'd do this:

gsap.killTweensOf(myObject, "opacity,x");

To kill all the delayedCalls (like ones created using gsap.delayedCall(5, myFunction);), you can simply callgsap.killTweensOf(myFunction); because delayedCalls are simply tweens that have their target and onComplete set to the same function (as well as a delay of course).

You can also pass in a string that defines selector text, like "#myID" to kill the tweens of the element with an ID of "myID" or "*" to kill all tweens with DOM targets. You may also pass in an array of targets.

killTweensOf() affects tweens that haven't begun yet too. If, for example, a tween of myObject has a delay of 5 seconds andgsap.killTweensOf(myObject) is called 2 seconds after the tween was created, it will still be killed even though it hasn't started yet.
