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>
