catelogs = new Array();
catelogs[ds]= new Array("计算机(IT)类-不限","Information Technology","1000",1)
catelogs[cs]= new Array("技术总监CTO","Tech. Majordomo, CTO","1019",0)
catelogs[gdf]= new Array("信息主管/CIO","Information Majordomo, CIO","1020",0)
catelogs[df]= new Array("项目经理","Project Manager","1021",0)
catelogs[xvvv]= new Array("数据库开发与管理(DBA)","Database Administration","1003",0)


php里可以用
foreach($catelogs as $key => $tag )
因为有$key所以可以使用这个数组

问JavaScript有什么办法
