Get the window height
<p>This is frustrating me. It should be something really simple but I can't get it to work in IE. I want to get the height of the current window: Not the scroll height, not the document height, but the actual window height. I've tried <code>window.innerHeight</code> which returns <code>undefined</code> and <code>document.documentElement.clientHeight</code> which gives the scroll height.</p>
