Is the IE implementation of those properies broken or missing? I get
'undefined' with both. The same holds true with the x and y
properties of Link and Anchor objects. However, the x and y
properties of the event object have values.

IE does not implement them at all. They are the preferred values to read
but if absent (so in IE) the scrollTop and scrollLeft values can be read
from the root element. Exactly which element is the root element depends
on the browser/version _and_ (if it exists) the "compatMode ".

In the absence of pageXOffset/YOffset value I would test to see if
document.compat Mode is defined, if it is not then the root element is
document.body. If it is defined and holds the string value "CSS1Compat "
then the root element is document.docume ntElement (the HTML element) and
the scroll values should be read from there. Any other values of
document.compat Mode ("BackCompat ", "QuirksMode ", etc) mean that
document.body is still the root element and it should be read for the
required values.

I used document.body.s crollTop and it worked a treat. I take it i should put in
pageXOffset for other browsers tho.

Yes, you should:

if (typeof pageXOffset != "undefined" )
{
... pageXOffset ...
}
else if (/* test suggested by Richard */)
{
... referenceToRoot Element.scrollT op ...
}

Yes, you should:

if (typeof pageYOffset != "undefined" )
{
... pageYOffset ...
}
else if (/* test suggested by Richard */)
{
... referenceToRoot Element.scrollT op ...
}


The same goes for `pageXOffset' and `scrollLeft'.
