json result returns error

Question

I have a json array

var states = { "1": "California", "2": "LA" };

How can i count and print the items in states. It should print 2.

if I use states.length it gives an error

Answer 1

If you need to count the members of an object you can do this:

for (val in states) {
    alert(states[val]);
    count++;
}
alert(count);

Answer 2

Thats not an array.

var states = [ "California", "LA" ];
