Alternatives to window.scrollMaxY?

android, javascript, webkit

Solution

I've got away with `document.body.scrollHeight` so that

document.body.scrollHeight = window.pageYOffset + screen height in pixels

at the end of the page (on Android).

Problem

I' trying to use window.pageYOffset & window.scrollMaxY to calculate the current page progress. This approach works under FF3.5 but under webkit window.scrollMaxY is undefined.
