Question

I would like to make an Object that has key names taken from a variable. Probably this is not clear enough, so let me make an example.

I have two variables var str1:String = ‘firstKey’; and str2:String = ‘secondKey’;

How can I make an object that would look like:

var obj:Object = {firstKey: ‘some value’, secondKey: ‘some other value’}, note that firstKey and secondKey are values of variables str1 and str2.

Doing obj = {str1: ‘some value’, str2: ‘some other value’} does not yield a result that I would like

Thanx a bunch for answers!

Answer 1

I’m not sure I understood correctly, but this might be what you want:

var str1:String = 'firstKey';
var str2:String = 'secondKey';

var myObj:Object = {}; // shorthand for a new object
myObj[str1] = 'some value';
myObj[str2] = 'some other value';

The strings within brackets are expanded, so really this is what happens:

myObj.firstKey = 'some value';
myObj.secondKey= 'some other value';
