Declare multi-dimensional array

[BananaQuaalude]

How do I declare a multi-dimensional array without initially entering any values into it?

I've tried:

var arrChange = new Array[[]]

which doesn't work.

thanks!

You mean something like this???

var i;
var first = newArray();
var second = newArray();
var all = second[first[i]];



I did it once for a class.
I can't remember if that's the right way to do it tho.


Assuming that's what u mean by a multi-dimensional array.

Anywayz, Hope it helps.

Okay, but I don't see the point of having the third array then. I only need two dimensions, so I can just assign the variables to each array separately, giving them each the same index number.

As in:

first[0] = variable1a
second[0] = variable1b

There has to be a way to declare a two-dimensional array without putting variables into it initially, so I can later assign like this:

arrData[0][0] = variable1a
arrData[0][1] = variable1b

???

Yep, try this:

<script type="text/javascript">
chars = new Array();
chars[0] = new Array(); //set chars[0] to be a new array
chars[0][0] = "a";
chars[0][1] = "b";
chars[0][2] = "c";
chars[1] = new Array(); //set chars[1] to be a new array
chars[1][0] = "1";
chars[1][1] = "2";
chars[1][2] = "3";
alert (chars[0][1]); //will alert the letter 'b'
alert (chars[1][2]); //will alert the number '3'
</script>

<script type="text/javascript">
<!--
doubleWide = new Array([],[],[]);
doubleWide[0][1] = Math.PI;
alert (doubleWide[0][1]);
// -->
</script>

Groovy.

Thanks to everyone!
