JavaScript animated smooth-scroll

Question

By default when you have fragment links like this:

<a href="/some-url#some-fragment">some text</a>

the browser just, scrolls down to that fragment instantly. How do i program it to smoothly move down to that fragment with standard JS?

Here's an example:

Example (To see the working example, just click on the 3 arrows inside the 3 circles and watch the smooth animated scrolling)

okay, i think i found my answer, posting it here to help others with the similar doubt:

<html>
  <head>
    <script type="text/javascript">
      var singleton = {};
      var timeout = singleton;

      window.onscroll = windowScroll;

      function windowScroll ()
      {
        var toTop = document.getElementById('toTop');
        toTop.style.display = ((window.scrollY > 0) ? "block" : "none");
      }

      function scrollStep ()
      {
        var y1 = window.scrollY - 1000;
        window.scrollTo(0, y1);

        if (y1 > 0)
        {
          timeout = window.setTimeout(scrollStep, 100);  
        }
        else if (timeout != singleton)
        {
          window.clearTimeout(timeout);   
        }
      }
    </script>

    <style type="text/css">
      #toTop {
        display: block;
        position: fixed;
        bottom: 20px;
        right: 20px;
        font-size: 48px;
      }

      #toTop {
        -moz-transition: all 0.5s ease 0s;
        -webkit-transition: all 0.5s ease 0s;
        -o-transition: all 0.5s ease 0s;
        transition: all 0.5s ease 0s;
        opacity: 0.5;
        display: none;
        cursor: pointer;
      }

      #toTop:hover {
        opacity: 1;
      }
    </style>
  </head>

  <body>
    <p id="top">your text here</p>
    <a href="#top" onclick="scrollStep(); return false" id="toTop"
       ><img src="images/go-to-top.png" alt="Go to top" title="Go to top"></a>
  </body>
</html>

Well you should try something like this

$('html,body').animate({
scrollTop:$("#ctl00_ctl00_ContentPlaceHolder1_Conten
tPlaceHolder1_txtcomment").offset().top
},'slow');

where *#ctl00_ctl00_ContentPlaceHolder1_ContentPlaceHolder1_txtcomment* is the id where you want to move or scroll

another approch is to put this in a function

function scrollme() {
$('html,body').animate({
scrollTop:$("#ctl00_ctl00_ContentPlaceHolder1_ContentPlaceHolder1_txtcomment").offset().top
},'slow');
} <a onclick="javascript:scrollme();">some text</a>

I hope this will help you.

A URI hash is a great way to make JavaScript/AJAX pages with dynamic content bookmarkable. It can be used in a manner similar to query strings, but changes will not cause a new page request. This allows you to store data in the URI which can be read and changed by JavaScript without ever reloading the page.

For the uninitiated, a URI location hash is everything after the # sign in the URI:

http://domain.com/page.html#i-am-a-hash A side note: URI hashes are not transferred back to the server, you can only access them client-side.
