find page length

[finerrecliner]

is there a function in JavaScript to find the total height of your
page? this value should INCLUDE the unseen space you have to scroll
down to see.

The Ypageoffset function seems to be close to what i want. but i want
the value when the scroll bar is at the bottom of the page at load
time, instead of waiting for the user to scroll down themselves.

any ideas? thanks.

It sounds like you want to know the page's maximum displacement. If so,
this is the way that I have done it in the past.
Instead of calculating from a range of properties, it attempts to
scroll down 10 Megapixels, then it reads the actual displacement before
scrolling back to the top.
Call it on load or later:

<SCRIPT type='text/javascript'>
function getScrollHeight()
{
var maxDisplacement=0;

window.scrollTo(0,10000000);

if( typeof self.pageYOffset!='undefined' )
maxDisplacement=self.pageYOffset;
else
if( document.compatMode && document.compatMode != 'BackCompat' )
maxDisplacement=document.documentElement.scrollTop;
else
if( document.body && typeof(document.body.scrollTop)!='undefined' )
maxDisplacement=document.body.scrollTop;

window.scrollTo(0,0);

return maxDisplacement;
}

window.onload=function(){alert(getScrollHeight())}
</SCRIPT>
