Is it possible to check the current alpha of an element in GSAP?


In other words I have a button that when clicked it changes the alpha of an element to .5 and I would like to be able to toggle the alpha from 1 to .5.


Something like...

function clickEvent{
 if(alpha == .5){
   TweenLite.to(".someElement", 1, {alpha: 1});
  TweenLite.to(".someElement", 1, {alpha: .5});

How is this typically done? Does GSAP has some property to check the opacity of an element or it needs to be done in pure Javascript?


Thanks a lot.
