<script type="text/javascript">     

       var openSubtabTimer = null;
       
       function openAssetSubtab() {
       
           // Use the results primary tab id and open a new subtab 
           var openSubtab = function(result) {               
                sforce.console.openSubtab(primaryTabId , '/' + assettab.Id, false,
                assettab.Name, null, null);           
                clearTimeout(openSubtabTimer);
