var $container = $('#container');
...
// when some route is matched
var view = new AnotherPage();
$container.html(view.render().el);

window.scrollTo(0, 0);

$container.html(el)
// jump to top if needed
if(historyManager.isUserJump(Backbone.history.fragment)) {
  window.scrollTo(0, 0)
}

// make body long enough to help browser jump to the right position
$body.css('min-height', '99999px')
// set dom
$container.html(el)
// jump to top if needed
if(historyManager.isUserJump(Backbone.history.fragment)) {
  window.scrollTo(0, 0)
}
// after 0.1s set min-height to a normal value
// hopefully no one will notice that
_.delay(function() {
  $body.css('min-height', '450px')
}, 100)
