jq animate volatile value

I am trying to create an animation for showing div elements with different amount of content in them. The divs start with 0 height and width and the goal is to first expand the width and then calculate the scrollHeight so i can divide it by 2 and split the height animation as follows.



let t = modal.position().top;
let h = 0;
modal.animate(width: '60%', 'fast').queue(function (next)
h = this.scrollHeight / 2; // Calculate at this point!
next();
).animate(height : h , 'fast').animate(height: (h * 2), top: (t-h), 'fast');


This doesn't work the way I expected it. 2nd and 3rd animations consider h to be 0! Any ideas/help would be great.

          OK, apparently the way to go is via the callback:



          let t = modal.position().top;
          modal.animate(width: '60%', 'fast', 'linear', function()
          let h = this.scrollHeight / 2;
          $(this).animate(height: h, 'fast')
          .animate(height: (h * 2), top: (t - h), 'fast');
          );
