Javascript array with custom variable indexing

Question

Is it possible to set the custom index of an array with a variable.

for example:

var indexID = 5;
var temp = {
    indexID: new Array()
};

The above example sets the array index to indexID and not 5. I have tried using = snd quotes but I without any success.

Answer 1

Yes, just use square brackets notation:

var temp = {};
temp[indexID] = [];

Also pay attention to the fact that temp is an object, and not an array. In JavaScript all associative arrays (or dictionaries) are represented as objects.

Answer 2

I think what you want is:

var indexID = 5;
var temp = {};
temp[indexID] = "stuff"

Answer 3

With your code, you will create an object.

Instead you can do

var indexID = 5;
var temp = [];
temp[indexID] = [];
