Question

I have a string like this:

var TheDate = "6.14.2012";

and I have an object MyObject that has properties that may match that string. However, when I write this:

if (MyObject[TheDate] === null || MyObject[TheDate] === 'undefined') { .... }

the conditions never seem to evaluate to true even though I know the property doesn’t exist.

What am I missing??

Thanks.

The problem is with the quotes around undefined 😉

Change

if (MyObject[TheDate] === null || MyObject[TheDate] === 'undefined') { .... }

to

if (MyObject[TheDate] === null || MyObject[TheDate] === undefined) { .... }

It should work 🙂
