Programmatically call anchor tag to Page Top at load time

I have a anchor tag that when you click on the "Up to the Top", it will move the web page to the top of the page. My anchor tag is #PAGETOP.

My question is, I am using the jQuery UI Dialog and basically would like to programmatically activate this #PAGETOP anchor so whenever the page always loads at startup, would like to ensure that the page moves immediately to the top of the page.

I would like to emulate the way stackoverflow moves to the top of all your questions when you paginate to the next page (if possible).

To move to the 'PAGETOP' anchor in Javascript, use this:

location.hash = 'PAGETOP';

If you're wanting to do it on page load, in jQuery it'd be like this:

$(function() {
  location.hash = 'PAGETOP';
});

Or take @Kip's idea and go pro with the scrollTo jQuery plugin. This plugin has additional options for different animations etc

<script>
     $.scrollTo( "#PAGETOP", 1000 );
</script>
