How i can control iframe hight from edge

Hi

I need to animate of hight size of iframe.

<iframe id="changeHight" src="edgeFile.html"></iframe>

iframe is calling adobe Edge File.

how can i create a code inside edgeFile.html, then this code will change iframe's hight.

i will explain another why about what i need.

so normaly i can change hight of Stage in Edge. it is ok. But i need to change iframe's hight in Edge too.

I used below such code to connect in Edge, but not succesfull

$("#changeHight", window.parent.document).html()

var myFooter = $("#changeHight", window.parent.document);

how can i change iframe's hight with Edge ?
