The error is on this line:

  var computedStyle = defaultView.getComputedStyle( elem, null );

defaultView=window and elem=window as well.

Resolution: invalid
Status: newclosed

Only the height method operates on the window. $(window).height()

It may make sense that $(window).innerHeight() is invalid but if you don't know that (doc don't say 'do not use window') you can, as I did, spent time chasing your tail. I spent time breaking down my code to the simplest example so that I could post this issue.

Can I propose either a documentation change, ideally with a reason why this is invalid or (and this is obviously more work) a better diagnostics message.

I went ahead and updated the docs to reflect that inner/outer methods only work on elements and to use width/height for document and window. As of right now there really isn't an inner/outer height of the window nor document. There is only the width/height. That is why using the inner/outer methods for window/document are invalid.

Sorry for the short explanation earlier. I understand the effort involved in debugging and posting a bug. Thanks for your effort and I hope this doesn't discourage you from doing so again in the future. :(

It may be worth mentioning that $(window).height() and window.innerHeight don't return the same value in Firefox. $(window).height() should be a clone of window.innerHeight for all browsers except IE, as it is the most reliable way of measuring the height of the inside of the viewport. For IE, the document.documentElement (for standards mode) and document.body (quirms mode) route should be used.
