Assigning variables to objects in JavaScript

Question

I am using the following method to basically create a JSON string.

var saveData = {};
saveData.a = 2;
saveData.c = 1;

However the .a and .c don't cut it for what I need to do, I need to replace these with strings. So something like..

var name = 'wibble';
saveData.name = 2;

This would get accessed with

saveData.wibble

Does anyone know how this could be achieved?

var name = "wibble";
saveData[name] = 2;

alert(saveData.wibble);

Note that, in JavaScript, the following notations are equivalent:

obj.key
obj["key"]

Use the map accessor:

var name = 'wibble'
saveData[name] = 2

You can access Javascript objects using a dictionary notation:

var name = 'wibble';
saveData[name] = 2;

saveData.wibble is now 2.
