Javascript-форум - открытие нового окна javascript

Есть такая проблема:

создаю новое окно по нажатию на кнопку в html форме.

приведенный ниже код работает нормально

str = "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\"><html><head><title>"
				+ "Poker" + "</title> </head> "
				+ "<body bgcolor='#000000' leftmargin='0' marginheight='0' marginwidth='0' rightmargin='0' topmargin='0'>"
			+ content + "</body></html>";

	  wnd.document.write(str);
   	  wnd.document.close();
	  return false;

но когда пишу вот так:

то данные окна выводятся Html при загрузке ( а должно после на onclick)

str = "<!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Transitional//EN' 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd'>"
+"<html xmlns='http://www.w3.org/1999/xhtml'>"

	  wnd.document.write(str);
   	  wnd.document.close();

	}

в результате в страницу вылазят левые плюсы:
