怎么写这个递归函数

JAVAScript已经定义好了，如下：var FirstMenuCount=25;
Menu1=new Array('0','32','-1','机构设置','../item_032/index.html','1');
Menu2=new Array('1','34','32','县局简介','../item_034/index.html','2');
Menu3=new Array('2','35','32','领导介绍','../item_035/index.html','2');
Menu4=new Array('3','36','32','机关科室','../item_036/index.html','2');
Menu5=new Array('4','110','32','直属机构','../item_0110/index.html','2');
Menu6=new Array('5','181','32','基层所','../item_0181/index.html','2');
Menu7=new Array('6','38','-1','新闻动态','../item_038/index.html','1');
Menu8=new Array('7','187','38','行业资讯','../item_0187/index.html','2');
Menu9=new Array('8','190','38','工作动态','../item_0190/index.html','2');
Menu10=new Array('9','401','38','纪检监察','../item_0401/index.html','2');
Menu11=new Array('10','322','-1','文件通知','../item_0322/index.html','1');
Menu12=new Array('11','323','322','国土资源部','../item_0323/index.html','2');
Menu13=new Array('12','324','322','省国土资源厅','../item_0324/index.html','2');
Menu14=new Array('13','325','322','市国土资源局','../item_0325/index.html','2');
Menu15=new Array('14','326','322','县委县政府','../item_0326/index.html','2');
Menu16=new Array('15','327','322','本局通知公告','../item_0327/index.html','2');
Menu17=new Array('16','316','-1','热点专题','../item_0316/index.html','1');
Menu18=new Array('17','317','316','科学发展观','../item_0317/index.html','2');
Menu19=new Array('18','318','316','基层干部培训','../item_0318/index.html','2');
Menu20=new Array('19','321','316','第20个全国“土地日”专题','../item_0321/index.html','2');
Menu21=new Array('20','328','316','2008年法律专题','../item_0328/index.html','2');
Menu22=new Array('21','329','316','第18个全国“土地日”专题','../item_0329/index.html','2');
Menu23=new Array('22','330','316','第19个全国“土地日”专题','../item_0330/index.html','2');
Menu24=new Array('23','331','-1','国土视频','../item_0331/index.html','1');
Menu25=new Array('24','332','-1','电子刊物','../item_0332/index.html','1');
