如何获得不同缩放级别的文档高度？

Question

I am using ASP.NET and C#.

document.documentelement.offsetHeight 

I am using this to find the height of the page. But it is differing based on zoom level. Now i need to get the base height(at 100% zoom) at all zoom level. Because using this i am doing some calculation to set height of other tags.

Is it possible?

Edit:

I did used this to detect the zoom level

((screen.deviceXDPI / screen.systemXDPI) * 100).toFixed();

But it is not accurate. Is there any other way to detect the zoom level?

Answer 1

document.height / $(document).height() should give you the zoom level. I've tested this on chrome - requires jquery
