ive got a problem getting parameters from a json chain, the json I got looks something like this

[{"aa":"bb","ccc":"ddd","eeee":"ffff","ggggg":"hhhhh","iiiiii":"jjjjjj","kkkkkkk":"lllllll"}]

Im trying to count how many pairs there are inside the '{}' but i dont know how. I tried json.length and json[0].length, the first one gave me back the value '1' and the second one undefined.

Your json object is an array containing one object. So the length is 1. The object in the array has multiple properties (key/value pairs).

So in most modern browsers (except IE), this would work for you:

Object.keys(json[0]).length
