Scroll to the top of the page using JavaScript?

Question

How do I scroll to the top of the page using JavaScript? The scrollbar instantly jumping to the top of the page is desirable too as I\'m not looking to achieve smooth scroll

Answer 1

With window.scrollTo(0, 0); is very fast
so i tried the Mark Ursino example, but in Chrome nothing happens
and i found this

$('.showPeriodMsgPopup').click(function(){
    //window.scrollTo(0, 0);
    $('html').animate({scrollTop:0}, 'slow');//IE, FF
    $('body').animate({scrollTop:0}, 'slow');//chrome, don't know if Safari works
    $('.popupPeriod').fadeIn(1000, function(){
        setTimeout(function(){$('.popupPeriod').fadeOut(2000);}, 3000);
    });
});

tested all 3 browsers and it works
i'm using blueprint css
this is when a client clicks "Book now" button and doesn't have the rental period selected, slowly moves to the top where the calendars are and opens a dialog div pointing to the 2 fields, after 3sec it fades
