二维数组怎么赋值 定义!

[hhfh]

function window_onload() {
var i;
var my_array = new Array(3,1);
my_array[0,0] = "MON";
my_array[0,1] = "1";

my_array[1,0] = "TUE";
my_array[1,1] = "2";

my_array[2,0] = "MON";
my_array[2,1] = "1";


my_array[3,0] = "THE";
my_array[3,1] = "33";


for (i=0;i<4;i++)
{alert(i+"="+my_array[i,1]+"="+my_array[i,0]);}

}

alert(i+"="+my_array[i,1]+"="+my_array[i,0]);} 为什么得到的my_array[i,0]值都是最后的
0=33=the

my_array[3,0] = "THE";
my_array[3,1] = "33";

刚发的有点错误:
alert(i+"="+my_array[i,1]+"="+my_array[i,0]);} 为什么得到的my_array[i,0]值都是最后的
my_array[3,0] 的值 THE
i变量是变化的
0=33=THE
1=33=THE
2=33=THE
3=33=THE

同意楼上的
var subcat = new Array();
subcat[0]=new Array(a[0],b[0]);

javascript不支持这样，你只能这样
<script>
var i;
var my_array = new Array(new Array(),new Array(),new Array(),new Array())
my_array[0][0] = "MON";
my_array[0][1] = "1";
my_array[1][0] = "TUE";
my_array[1][1] = "2";
my_array[2][0] = "MON";
my_array[2][1] = "1";
my_array[3][0] = "THE";
my_array[3][1] = "33";
for (i=0;i<4;i++)
{alert(i+"="+my_array[3][1]+"="+my_array[i][0]);}
</script>
