javascript - How to add smooth scrolling to Bootstrap's scroll spy function

Question

I've been trying to add a smooth scrolling function to my site for a while now but can't seem to get it to work.

Here is my HTML code relating to my navigation:

<div id="nav-wrapper">
<div id="nav" class="navbar navbar-inverse affix-top" data-spy="affix" data-offset-top="675">
  <div class="navbar-inner" data-spy="affix-top">
    <div class="container">

      <!-- .btn-navbar is used as the toggle for collapsed navbar content -->
      <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </a>

      <!-- Everything you want hidden at 940px or less, place within here -->
      <div class="nav-collapse collapse">
        <ul class="nav">
            <li><a href="#home">Home</a></li>
            <li><a href="#service-top">Services</a></li>
            <li><a href="#contact-arrow">Contact</a></li>
        </ul><!--/.nav-->
      </div><!--/.nav-collapse collapse pull-right-->
    </div><!--/.container-->
  </div><!--/.navbar-inner-->
</div><!--/#nav /.navbar navbar-inverse-->
</div><!--/#nav-wrapper-->

Here is the JS code I've added:

<script src="js/jquery.scrollTo-1.4.3.1-min.js"></script>

<script>
    $(document).ready(function(e) {

        $('#nav').scrollSpy()
        $('#nav ul li a').bind('click', function(e) {
            e.preventDefault();
            target = this.hash;
            console.log(target);
            $.scrollTo(target, 1000);
        });
    });
</script>

For what it's worth, here is where I received info on what I've done so far, and here is my site in it's current form. If you can help me I'll bake you a pie or cookies or something. Thanks!

Do you really need that plugin? You can just animate the scrollTop property:

$("#nav ul li a[href^='#']").on('click', function(e) {

   // prevent default anchor click behavior
   e.preventDefault();

   // store hash
   var hash = this.hash;

   // animate
   $('html, body').animate({
       scrollTop: $(hash).offset().top
     }, 300, function(){

       // when done, add hash to url
       // (default click behaviour)
       window.location.hash = hash;
     });

});
