JavaScript menu - opening links in a full window

[tOKmaZ]

I'm not very familiar to JavaScript yet (I started, learning HTML 1 month ago... when I was building my first webpage), and got problems with a menu. I can't figure out how to make the link open in the whole window (like TARGET="_parent"), not only in the frame the menu is placed in...

Here's the script, and i would be really glad if someone could help me, and correct the script for me (all the sub items, or what ever). Please don't make it too complicated... i'm only 14 yrs.o.:

//Top Nav bar script v2.1- http://www.dynamicdrive.com/dynamicindex1/sm/index.htm

function showToolbar()
{
// AddItem(id, text, hint, location, alternativeLocation);
// AddSubItem(idParent, text, hint, location, linktarget);

menu = new Menu();
menu.addItem("infoid", "Info", "Info", null, null);
menu.addItem("contactid", "Contact", "Contact", null, null);
menu.addItem("fundownid", "Fun & Downloads", "Fun & Downloads", null, null);
menu.addItem("miscid", "Miscellaneous", "Miscellaneous", null, null);
menu.addItem("realid", "Real Stuff", "Real Stuff", null, null);

menu.addSubItem("infoid", "General Info", "General Info", "http://alorniac.clan.rottenass.com/info.htm", "");
menu.addSubItem("infoid", "Member List", "Member List", "http://alorniac.clan.rottenass.com/members.htm", "");
menu.addSubItem("infoid", "Unreal Servers", "Unreal Servers", "http://alorniac.clan.rottenass.com/servers.html", "");


menu.addSubItem("contactid", "Contact Us", "Contact Us", "http://alorniac.clan.rottenass.com/contact.htm", "");
menu.addSubItem("contactid", "Join the clan", "Join the clan", "http://alorniac.clan.rottenass.com/join.htm", "");

menu.addSubItem("fundownid", "Unreal Quiz", "Unreal Quiz", "http://alorniac.clan.rottenass.com/quiz.htm", "");
menu.addSubItem("fundownid", "Unreal Downloads", "Unreal Downloads", "http://alorniac.clan.rottenass.com/", "");
menu.addSubItem("fundownid", "Unreal Forum", "Unreal Forum", "http://alorniac.clan.rottenass.com/forum.htm", "");

menu.addSubItem("miscid", "Unreal Links", "Unreal Links", "http://alorniac.clan.rottenass.com/links.htm", "");
menu.addSubItem("miscid", "Unreal Shop", "Unreal Shop", "http://alorniac.clan.rottenass.com/shop.htm", "");

menu.addSubItem("realid", "My WebHost", "My WebHost", "http://web1000.com/", "");
menu.addSubItem("realid", "FreeDomains - .tk", "FreeDomains - dot.tk", "http://dot.tk/", "");
menu.addSubItem("realid", "FreeDomains - .co.nr", "FreeDomains - .co.nr", "http://freedomains.co.nr/", "");
menu.addSubItem("realid", "Webmasters - VISIT", "Webmasters - VISIT", "http://webproworld.com/", "");


menu.showMenu();
}
