Jquery Function Scroll To

I have a JQuery function that closes a <div>

$(document).ready(function() {	
	$('input[type="button"]').click(function() {
		if ($(this).attr("value") == "custom-done") {
			$("#custom-hidden").hide('slow');
		}
	});

HTML:::
<input id="edd-purchase-button" class="edd-submit gray button" type="button" value="custom-done" name="done-customizing">

Select allOpen in new window

Currently when I click the button, it scrolls to the bottom of the page.  I want to scroll to the top of the page when I click the button.

Any suggestions?
