how can i get current tween values

TweenMax.to(div, 2, {
  css: {
    top: 200,
  },
  onUpdate(self) {
    // get current top value
    console.log(self.vars.css.top);
  },
  onUpdateParams: ["{self}"],
});

I'd recommend using y and then get the data from the gsTransform object, but if you want to use top, getBoundingClientRect() would be my choice.

i need to get different values from different tweens and getBoundingClientRect cause browser reflow, don't think it's good idea do this.

maybe tm store somewhere values that set ?

As I said, I wouldn't animate 'top'. I'd use 'y' and then all the info you need is in the transform object.

As for your original code, you'll want this instead:

this.target[0].style.top

 

If you have other ideas, feel free to implement them. If you have GSAP related questions, we're happy to help.
