[jQuery] Can I use a variable to reference object properties?

[cbandes]

Hi - I have a function which iterates through a json file in order to
build an FAQ page. Within the json are several different categories,
and I want to make a generic function that will return only the
appropriate items from the chosen category.

Currently it looks like this:

        $.getJSON("faq_json.js", function(data)
        {
          $.each(data.cheese, function(i, item)
            { do a ton of stuff
    }

But let's say I want to display stuff that isn't in data.cheese - like
the stuff from data.meat or data.bread - currently I would need to
hardcode those in.

What I had hoped to do was this:

var myCategory = "cheese";
$.each(data.myCategory, function(i, item)
            { do a ton of stuff
    }

But that doesn't work. I'm sure there's a simple fix, but I have no
idea where to look... (Yeah, I'm a n3wB ;) thanks for your patience!)
