Question

EXAMPLE: http://jsbin.com/ewiko4/5/

So I have some Dynamic divs that I need to figure out the height of when they change. I can get the height when the document loads but it won’t update.

In the example I’ve added a make bigger button but irl it will be changed via jq & ajax

Yup, I can’t add a callback to the animation button because it wont’t be there.

Answer 1

Take a look at this edit of your jsbin.

Couple of changes:

1. Your window events could be binded at the same time with $(window).bind('load resize', resizeFrame)

2. You want to call the resizeFrame as a callback of the animation to let it know the sizes changed…

3. If you don’t have control of the animation function changing the height (as indicated by your comment) you can use a setInterval to poll the heights.

---

setInterval(resizeFrame, 150);

Would call your resizeFrame function every 150 ms. You can check the heights, see if they’ve changed, and do whatever you need to…
