JavaScript – How to Get the Window Height

javascript

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 window.innerHeight which returns undefined and document.documentElement.clientHeight which gives the scroll height.

Best Answer

For current browsers

window.innerHeight

For IE 8 and lower, use

document.documentElement.offsetHeight;

If you need older browsers, use:

var height = "innerHeight" in window 
               ? window.innerHeight
               : document.documentElement.offsetHeight;
