Answer 1

I searched on because n o n e of the here posted functions seemed to work, i always got the windowviewheight not the documents full height...

this works in all browsers I've tested...also iexplore 8:

var D = document;
var myHeight = Math.max(
    D.body.scrollHeight, D.documentElement.scrollHeight,
    D.body.offsetHeight, D.documentElement.offsetHeight,
    D.body.clientHeight, D.documentElement.clientHeight
);

alert(myHeight);
