jQuery cross-browser "scroll to top", with animation

You're returning true from the click function, so it won't prevent the default browser behaviour (i.e. navigating to thego-to-top anchor. As Mark has said, use:

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

So your code should now look like:

$('#go-to-top').each(function(){    $(this).click(function(){         $('html,body').animate({ scrollTop: 0 }, 'slow');        return false;     });});

To get it to work in opera this answer proved helpful.

Putting that with your click()

$(this).click(function() {    $(window.opera ? 'html' : 'html, body').animate({        scrollTop: 0    }, 'slow');});

Code example on jsfiddle.

Side note if all you are doing with the .each() is assigning a click handler you do not need to iterate over the collection it can be simplified to this:

$('#go-to-top').click(function(){     $(window.opera ? 'html' : 'html, body').animate({        scrollTop: 0        }, 'slow');});

Also if there is more than one element with id #go-to-top your markup will be invalid, try switching it to a class .go-to-top

maybe something like

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

aswell as the html one.

$('#go-to-top').each(function(){  $(this).click(function(){     $('html').animate({ scrollTop: 0 }, 'slow'); return true;     $('body').animate({ scrollTop: 0 }, 'slow'); return true;     $('document').animate({ scrollTop: 0 }, 'slow'); return true;     $('window').animate({ scrollTop: 0 }, 'slow'); return true;   });});

should cover all browsers!
