I have JSON object inside variable like this:

var chessPieces = 
 "p-w-1" : 
 "role":"pawn",
 "position":"x":1, "y":2,
 "state":"free",
 "virgin":"yes"
 ,
 "p-w-2" : 
 "role":"pawn",
 "position":"x":2, "y":2,
 "state":"free",
 "virgin":"yes"
 ,...
;

And I'm iterating trough them with for each loop:

for (var piece in chessPieces)
 //some code

How would I get current pieces name from this? For example, we are currently on the first element(piece = 0): chessPiece[piece].GiveMeTheName ==> which results in string "p-w-1".

I actually intend to pass the current element into the function, cos I need to check something, so it would look something like this:

//constructor for this function looks like this: function setPiece(piece,x,y);
function setPiece(chessPiece[piece],chessPiece[piece].position.x,chessPiece[piece].position.y)
 //and here I need to get something like
 piece.GiveMeTheName ==> which gives me string "p-w-1"

I'm also using jQuery in my project, so if there's something usable in that library, let me know.

Erm. Isn't piece already the name of the object? The for ... in in JavaScript gives you the key name.

So when you do for (var piece in chessPieces) console.log(piece);, it will print out p-w-1, p-w-2 etc

I'd use $.each(obj, fn). The function allows access to the object key of the current element.

$.each(chessPieces, function(key, value) 

 //key = "p-w-1"
 //value = "role":"pawn", ... 
 //this === value

);

for (var piece in chessPieces)
 alert(piece)
