Smooth scrolling of name tags (anchor) in HTML using jQuery

Smooth scrolling of name tags (anchor, <a>) in HTML using jQuery

Got this from some blog.� I don’t remember the link.

$(function(){
 $('a[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) {
 var targetOffset = $target.offset().top;
 $('html,body')
 .animate({scrollTop: targetOffset}, 1000);
 return false;
 }
 }
 });
});
