jQuery Smooth Scrolling

scroll.js

$(function() {
 
  // scroll handler
  var scrollToAnchor = function( id ) {
 
    // grab the element to scroll to based on the name
    var elem = $("a[name='"+ id +"']");
 
    // if that didn't work, look for an element with our ID
    if ( typeof( elem.offset() ) === "undefined" ) {
      elem = $("#"+id);
    }
 
    // if the destination element exists
    if ( typeof( elem.offset() ) !== "undefined" ) {
 
      // do the scroll
      $('html, body').animate({
        scrollTop: elem.offset().top
      }, 1000 );
 
    }
    
  };
  
 
  // bind to click event
  $("a").click(function( event ) {
   
    // only do this if it's an anchor link
    if ( $(this).attr("href").match(/^#/) ) {
      
      // prevent default propagation
      event.preventDefault();
      
      // scroll to the location
      var href = $(this).attr('href').replace('#', '');
      scrollToAnchor( href );

      // if we have pushState
      if ( history.pushState ) {
        history.pushState( null, null, '#'+href );
      }
			   
      // fallback to prevent jitter
      return false;
 
    }
 
  });
 
});

Just fixed an issue that prevented external links that had hashtags from working correctly. It now ensures the "href" attribute of the link starts with '#' rather than just containing it.
