Make the web browser scroll to the top?

Question

What is the JavaScript to scroll to the top when a button/link/etc. is clicked?

Answer 1

<a href="javascript:scroll(0, 0)">Top</a>

Answer 2

If you had an anchor link at the top of the page, you could do it with anchors too.

<a name="top"></a>
<a href='#top">top</a>

It'll work in browser's with Javascript disabled, but changes the url. :( It also lets you jump to anywhere the name anchor is set.
