ScrollTO

If you want the URL to be updated, do it within the animate callback:

$('a[href^="#"]').on('click',function (e) {
        e.preventDefault();

        var target = this.hash,
            $target = $(target);
        $('html, body').stop().animate({
            'scrollTop': $target.offset().top
        }, 900, 'swing', function () {
            // window.location.hash = target;
        });
    });


// Removes hash from url

$('a[href*=#]:not([href=#])').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') 
        || location.hostname == this.hostname) {

      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top
        }, 1000);
        return false;
      }
    }
});
