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');
          
        });
