how to make an array with 2 dimensions?

[Dave]

Hi,

i tried this:
a=new Array()
for (i=1;i<=3;i++)
{
for (j=1;j<=2;j++)
a[i,j]=i+j
}

for (i=1;i<=3;i++)
{
for (j=1;j<=2;j++)
alert(a[i,j])
}

but i get 4,5,4,5,4,5 while i expect 2,3,3,4,4,5
Thanks
Dave

a=[];
for (i=1;i<=3;i++) {
a[i] = [];
for (j=1;j<=2;j++)
a[i][j] = i+j;
}

for (i=1;i<=3;i++) {
for (j=1;j<=2;j++)
alert(a[i][j]);
}

You can only create an array of arrays with JavaScript
var a = new Array();
for (var i = 0; i < 5; i++) {
a[i] = new Array();
for (var j = 0; j < 10; j++) {
a[i][j] = j;
}
}
