How to scroll to specific item using jQuery?

Dead simple. No plugins needed.

var $container = $('div'),
    $scrollTo = $('#row_8');

$container.scrollTop(
    $scrollTo.offset().top - $container.offset().top + $container.scrollTop()
);

// Or you can animate the scrolling:
$container.animate({
    scrollTop: $scrollTo.offset().top - $container.offset().top + $container.scrollTop()
});​

Here is a working example.

Documentation for scrollTop.

I realise this doesn't answer scrolling in a container but people are finding it useful so:

$('html,body').animate({scrollTop: some_element.offset().top});

We select both html and body because the document scroller could be on either and it is hard to determine which. For modern browsers you can get away with $(document.body).

Or, to go to the top of the page:

$('html,body').animate({scrollTop: 0});

Or without animation:

$(window).scrollTop(some_element.offset().top);

OR...

window.scrollTo(0, some_element.offset().top); // native equivalent (x, y)
