javascript - ScrollTo Effect (href to div) -

-

i can't seem find working simple scrollto effect. want basic, it's when click on link in nav bar, must take me selected div id scrollto effect.

this code have.

<nav> <ul> <li><a href="#home">home</a></li> <li><a href="#about">about</a></li> <li><a href="#contact">contact</a></li> </ul> </nav>  <section id="home">   content </section>  <section id="about">   content </section>  <section id="contact">   content </section>

js:

<!----- navegación slide --->    $(document).ready(function() {   $('a[href*=#]').each(function() {     if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'')     && location.hostname == this.hostname     && this.hash.replace(/#/,'') ) {       var $targetid = $(this.hash), $targetanchor = $('[name=' + this.hash.slice(1) +']');       var $target = $targetid.length ? $targetid : $targetanchor.length ? $targetanchor : false;        if ($target) {          var targetoffset = $target.offset().top;  <!----- funcion click + scroll al #div--->             $(this).click(function() {             $("nav ul li a").removeclass("active");             $(this).addclass('active');            $('html, body').animate({scrolltop: targetoffset}, 1000);            return false;          });       }     }   });  });

this seems work, doesnt take me top of selected section. takes middle of section's content.

use jquery here fiddle http://jsfiddle.net/4qt9h95n/1/

$('a[href^="#"]').click(function() {      $('html,body').animate({ scrolltop: $(this.hash).offset().top}, 1000);      return false;      e.preventdefault(); });
