What I mean by that is say I have JSON data as such:

[{"ADAM":{"TEST":1}, "BOBBY":{"TEST":2}}]

and I want to do something like this:

var x = "ADAM";
alert(data.x.TEST);

you have to loop through them because I guess adam/bobby is not static. Something like data[i].x.TEST – Fredrik May 15 '11 at 18:24

var data = [{"ADAM":{"TEST":1}, "BOBBY":{"TEST":2}}],
    x = "ADAM";

alert(data[0][x].TEST);

Since objects in javascripts are handled just like hashmaps (or associative arrays) you can just do data['adam'].TEST just like you could do data.adam.TEST. If you have a variable index, just go with the [] notation.

var data = [{"ADAM":{"TEST":1}, "BOBBY":{"TEST":2}}]
alert(data[0].ADAM.TEST);
alert(data[0]['ADAM'].TEST)

if you just do

var data = {"ADAM":{"TEST":1}, "BOBBY":{"TEST":2}};

you could access it using data.ADAM.TEST and data['ADAM'].TEST

That won't work as you're setting x to be a string object, no accessing the value from your array:

alert(data[0]["ADAM"].TEST);
