Question

How to scroll to div (e.g: #about, #contact) after click on About or Contact in my menu?

<div class="masthead">
    <ul class="nav nav-pills pull-right">
        <li class="active"><a href="#">Home</a></li>
        <li><a href="#">About</a></li>
        <li><a href="#">Contact</a></li>
    </ul>
    <h3 class="muted">Name site</h3>
</div>

Answer 1

Your html:

<div class="masthead">
    <ul class="nav nav-pills pull-right">
        <li class="active"><a href="#">Home</a></li>
        <li><a href="#about">About</a></li>
        <li><a href="#contact">Contact</a></li>
    </ul>
    <h3 class="muted">Name site</h3>
</div>
<div id="about">about</div>
<div id="contact">contact</div>

Your javascript:

$('ul.nav').find('a').click(function(){
    var $href = $(this).attr('href');
    var $anchor = $('#'+$href).offset();
    window.scrollTo($anchor.left,$anchor.top);
    return false;
});

If you want to use animate, replace

window.scrollTo($anchor.left,$anchor.top);

by

$('body').animate({ scrollTop: $anchor.top });

Answer 2

It is easier than you think.

  <div class="masthead">
    <ul class="nav nav-pills pull-right">
      <li class="active"><a href="#">Home</a></li>
      <li><a href="#About">About</a></li>
      <li><a href="#Contact">Contact</a></li>
    </ul>
    <h3 class="muted">Name site</h3>
  </div>


<div id="About">Here's my about</div>

...

<div id="Contact">Here's my contact</div>

By using the hash, it'll auto scroll to an element with that id (or an anchor with that name attribute). If you want it to scroll smoothly you can enhance the scroll effect with a javascript library, like jquery. See this question: How to scroll HTML page to given anchor using jQuery or Javascript?
