How can I get facebook window height from iframe?

javascript

Solution

If your're using the Facebook JavaScript SDK, you could use `FB.Canvas.getPageInfo()`

FB.Canvas.getPageInfo(
    function(info) {
        console.log('Height: ' + info.clientHeight);
    }
);

Problem

I want to get facebook window height using javascript from my iframe. However window.innerHeight gives me the height of the iframe. How can I solve this problem ?
