How to jump to top of browser page
You can set the scrollTop, like this:
$('html,body').scrollTop(0);Or if you want a little animation instead of a snap to the top:
$('html, body').animate({ scrollTop: 0 }, 'fast');
If you're using jQuery UI dialog, you could just style the modal to appear with the position fixed in the window so it doesn't pop-up out of view, negating the need to scroll. Otherwise,
var scrollTop = function() { window.scrollTo(0, 0);};should do the trick.
