TabBar events

You can set event handler for tab selection. If it returns false then tab selection will not be changed.

 
<script> 
            function my_func(idn,ido){
                if (confirm("Tab "+idn+" to set active\nPlease Confirm?"))
                    return true;
                return false;
            };
 
            tabbar=new dhtmlXTabBar("a_tabbar","top");
               ...            
            tabbar.setOnSelectHandler(my_func);
            tabbar.loadXML("tabs1.xml");</script>
