Hello people,

I am trying to run this javascript for tab browsing. Although I created a sample javascript for alert and it worked fine but this code isn't executing. I know we gotta write the code in Advance Setting > header / Footer .. please lemme know the error

 

<script type="text/javascript">

    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>

Do you know if there is an example of how to do this? I don't know anything about JQuery and can't figure out how to get into my module.

I am needing to send the user one of 2 alerts depending upon if they click a link to add an item to their dashboard and 1) it doesn't exist yet or 2) it already exists in their dashboard.

Thanks!
