Question

Let’s say I have this:

var ObjectKey = "06.2012";

It’s a string that represents the month. I want to use this value as the key of a new object. I have

TheObject = {ObjectKey: null};

But when I go to the console, instead of the TheObject having a key named 06.2012, it has a key named ObjectKey.

How do I create a key that has the name of a string that I create at runtime?

Thanks.

Answer 1

To use variable as the key you need to use the [] syntax..

var ObjectKey = "06.2012";
TheObject = {};
TheObject[ObjectKey] = null;
