Javascript Link to tabs

I have a full tab system working with the following code. When you click on A LI link it hides the other divs and shows the selected div.

<script type="text/javascript">
    //<![CDATA[

    var tabLinks = new Array();
    var contentDivs = new Array();

    function init() {

      // Grab the tab links and content divs from the page
      var tabListItems = document.getElementById('tabs').childNodes;
      for ( var i = 0; i < tabListItems.length; i++ ) {
        if ( tabListItems[i].nodeName == "LI" ) {
          var tabLink = getFirstChildWithTagName( tabListItems[i], 'A' );
          var id = getHash( tabLink.getAttribute('href') );
          tabLinks[id] = tabLink;
          contentDivs[id] = document.getElementById( id );
        }
      }

      // Assign onclick events to the tab links, and
      // highlight the first tab
      var i = 0;

      for ( var id in tabLinks ) {
        tabLinks[id].onclick = showTab;
        tabLinks[id].onfocus = function() { this.blur() };
        if ( i == 0 ) tabLinks[id].className = 'selected';
        i++;
      }

      // Hide all content divs except the first
      var i = 0;

      for ( var id in contentDivs ) {
        if ( i != 0 ) contentDivs[id].className = 'tabContent hide';
        i++;
      }
    }

    function showTab() {
      var selectedId = getHash( this.getAttribute('href') );

      // Highlight the selected tab, and dim all others.
      // Also show the selected content div, and hide all others.
      for ( var id in contentDivs ) {
        if ( id == selectedId ) {
          tabLinks[id].className = 'selected';
          contentDivs[id].className = 'tabContent';
        } else {
          tabLinks[id].className = '';
          contentDivs[id].className = 'tabContent hide';
        }
      }

      // Stop the browser following the link
      return false;
    }

    function getFirstChildWithTagName( element, tagName ) {
      for ( var i = 0; i < element.childNodes.length; i++ ) {
        if ( element.childNodes[i].nodeName == tagName ) return element.childNodes[i];
      }
    }

    function getHash( url ) {
      var hashPos = url.lastIndexOf ( '#' );
      return url.substring( hashPos + 1 );
    }

    //]]>
    </script>

I want to be able open the tabs via this links. So that when i visit index.php#hello it will link to the div with the id hello. I tried simply visiting the link but this did not work... Thanks in advanced.

Assuming that you run init() on page load, just add the following inside that function:

if( window.location.hash )
    showTab();

You have the function showTab() executing when you click links to set the proper tab open, but not when the page loads, so it doesn't know to execute your code. Having it run once if a hash location exists will help get you what you need.
