如何才能实现多维数组？能否用Array直接实现呢？谢谢！

Question

给个思路，其实很简单
var arr1=new Array()
arr1[i]=new Array(1,2,3)
以上是二维数组

Answer 1

O，你要的是三维数组var A3=new Array()
var A2=new Array()
var A1=new Array()
A1[0]=1
A2[0]=A1
A3[0]=A2
A3这就是三维了
A3[0][0][0]==1

Answer 2

<script>var cities=new Array();
cities[0]=new Array();
cities[1]=new Array();cities[0][0]=new Array("changsha","changde","yueyang");
cities[0][1]=new Array("wuhan","huangshi","yichang");
cities[1][0]=new Array("guangzhou","shenzhen");
cities[1][1]=new Array("nanning","liuzhou");alert(cities[0][0][0]);
alert(cities[1][0][1]);</script>
