Multi Dimensional Arrays

[jess]

HELP ME SOMEONE PLEEEEASE!!! I need to create a multi-dimensional array...(?) - and thats all I know.... (well almost!)

The thing is to build arrays of arrays.
For instance, you can define a two dimensional array like this :

var tMultiArray = new Array();
tMultiArray.push(new Array());

tMultiArray[0].push("toto");
tMultiArray[0].push("titi");

trace(tMultiArray[0][0]);
trace(tMultiArray[0][1]);

will give you that output :
toto
titi

Hope it helps,

I was looking for a solution on the forums and this thread was close to my problem so maybe someone could help me...

How do you "push" two arrays?

tMultiArray = new Array();
two = new Array();
two = [20, 30]

tMultiArray[0].push(two);

trace(tMultiArray[0][0]);

this doesn't work, unfortunately... what's wrong?

[senocular]

your problem is tMultiArray[0] isnt an array when you try to push something on it. you have to make it one first...

tMultiArray = new Array();
two = new Array();
two = [20, 30]

tMultiArray[0] = new Array();
tMultiArray[0].push(two);

trace(tMultiArray[0][0]); // 20, 30

The most straightforward way is to make each array element an array-

tMultiArray = new Array();

tMultiArray[0] = new Array();
tMultiArray[1] = new Array();
.
.
.
tMultiArray[n] = new Array();

tMultiArray[0][0] = "a";
tMultiArray[0][1] = "b";

etc.

trace(tMultiArray[0][0]+" . "+tMultiArray[0][1]);

Like dees, mayn!

Array.prototype.arr_two_dee=function(x,y) {
    for (var i=0;i<x;i++) {
        this[i]=[y];
    }
};
// use
arr_test=[];
arr_test.arr_two_dee(4,4);
// a grid
for (x=0;x<=3;x++){
    for (y=0; y<=3; y++){
        arr_test[x][y]='['+x+']['+y+']';
    }
}

I having the headache on the multi-dimensional array for the past few days. Finally I got it solved after reading through the thread overhere. Thanks.

But I still have the question for the Push in the script here. What do this push do in the array? I could not understand? Can anyone tell me more about it?

Thanks in advanced.
