As seen in https://developer.mozilla.org/En/DOM/Element.scrollTop, I can set the scrollTop proppety. And everything goes well if I don't specify the DOCTYPE but my setting function doesn't work when I add the following line:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
Reproducible: Always
Steps to Reproduce:
1.Here is a quick example to demonstrate the problem
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<script type="text/javascript" language="javascript1.5">
function goDown()
{
document.body.scrollTop=document.body.scrollHeight;
}
</script>
</head>
<body>
<button onClick="goDown();">Scroll Down</button>
<div style="height:5000px; width:500px; background-color:#999999;">Very large div element</div>
<button onClick="document.body.scrollTop=0">Scroll Up</button>
</body>
</html>
2.open it with Mozilla Firefox 5.0
3.click on Scroll Down button
4.change the code removing the first line
5.repeat steaps 2 and 3
6.it works without DOCTYPE especification
Actual Results:
my Scroll Down button doesn't scroll down the page
Expected Results:
Scroll down button scrolls the page to the bottom

I suspect you need to set it to <value>px in standards mode. Does that work if you do?

Thanks Robert for your quick reply but set it with the "px" still that doesn't work, and now it neither works on explorer, here is the example code with the change you suggested
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<script type="text/javascript" language="javascript1.5">
function goDown()
{
document.body.scrollTop=document.body.scrollHeight+"px";
}
</script>
</head>
<body>
<button onClick="goDown();">Scroll Down</button>
<div style="height:5000px; width:500px; background-color:#999999;">Very large div element</div>
<button onClick="document.body.scrollTop='0px'">Scroll Up</button>
</body>
</html>

No. This a |long| IDL attribute.
In any case, this is expected behaviour per spec:
