Cognos BI Javascript to select a tab in multi-page dashboard

Overwhelmed with work but still alive and have some proof: a quick javascript recipe that allows you to add hyperlinks to select tabs in multi-page dashboard reports. Something like multi-page tab drill-through ) Googled around and haven’t found anything copy-ready, so here it goes.

We want to have a link like in picture below and clicking on it should transfer us to Sales tab.

How to do this:

Add following Javascript to the page:

<script type="text/javascript">
function clickTabByName(tabName)
{
     //all links on page, tabs are links
     var allElements = document.getElementsByTagName('a');
     for (var i = 0; i < allElements.length; i++)
       {
         // all links with role = 'tab'
          if (allElements[i].outerHTML.indexOf('role="tab"')!==-1)
           {
               // Check tab name
               if  (allElements[i].innerHTML == tabName)
               {
                      //alert(allElements[i].innerHTML);
                      allElements[i].click();
                 }
           }
       }
}

Add a new hyperlink object to the report with following URL

javascript:clickTabByName('Sales');

Tested only for 10.1.1 fp1, but it should work in all 10 versions. I’m using “role='tab’” tag that Cognos 10 (dojo framework) generates for tab names, this could be different in 8 or CRN (but I doubt it and am too tired to check).

Update 11/06/2013:

Was asked for Cognos 8 version (one above is 10+ only), so here it goes. Only one line (to filter out tabs from other links) is changed:

<script type="text/javascript">
function clickTabByName(tabName)
{
     //all links on page, tabs are links
     var allElements = document.getElementsByTagName('a');
     for (var i = 0; i < allElements.length; i++)
       {
         // in Cognos 8 all tabs have href="javascript:noop()" attribute
        if (allElements[i].outerHTML.indexOf('href="javascript:noop()"')!==-1)
          {
               // Check tab name
               if  (allElements[i].innerHTML == tabName)
               {
                    //  alert(allElements[i].innerHTML);
	// alert(allElements[i].outerHTML);
                      allElements[i].click();
                 }
          }
       }
}
</script>
