JavaScript change page effect

Hi by any chance anyone will know how to do the fade in fade out change
page effect in JavaScript?
Like this.. http://soulwire.co.uk/hello
I have tried this..
But when fadeout is not linking together..I mean not smooth like the above
website.
$(document).ready(function() { $('body').css('display', 'none');
$('body').fadeIn(1000); $('.link').click(function() {
event.preventDefault(); newLocation = this.href; $('body').fadeOut(2000,
newpage); }); function newpage() { window.location = newLocation; } });
