I have an Uncaught SyntaxError: Unexpected token : on a getJSON call. Why?

Question

I use a restfull api http://applications.opap.gr/DrawsRestServices/kino/last.json

This url returns in json format the "numbers games" that have won in a game called "kino"

the results in browser is something like this:

{"draw":{"drawTime":"18-04-2014T10:15:00","drawNo":437017,"results":[6,9,12,16,17,21,24,26,31,36,38,53,54,55,61,63,67,69,75,79]}}

I am trying to get these numbers by using a jquery function:

function get_game_results_json() {
$.getJSON("http://applications.opap.gr/DrawsRestServices/kino/last.json?callback=?", function(result){
   alert(result);
});
}

a) My first problem is that when I go to the tab console of google chrome I have "Uncaught SyntaxError: Unexpected token : "

But att the same time in the tab network I have a response that looks it works

draw: {drawTime:18-04-2014T10:20:00, drawNo:437018,…}
  drawNo: 437018
  drawTime: "18-04-2014T10:20:00"
  results: [6, 8, 15, 28, 32, 33, 37, 38, 39, 40, 45, 50, 58, 59, 68, 69, 72, 75, 79, 80]

Why I have Unexpected token ? Any ideas?

b) Could you suggest a way to parse correctly the json response and store each node of json into a different variable ?

drawNo drawtime results

Cross-origin? If so, the server probably needs to support JSONP instead of raw JSON. {"a":"b", ...} is not valid Javascript code, and hence the error. — UltraInstinct
That could be the first object in responce, which has time with :. — Jai
You are not using JSON. You are using JSONP since the server doesn't seem to support cross-domain requests. — Derek 朕會功夫

You are making a cross-origin call with a callback argument. This means you are using JSONP.

The response you are getting is JSON, not JSONP.

Trying to parse JSON as JSONP will throw an error.

The API you are accessing doesn't appear to support anything that will enable a cross-origin request. Get data from it using your server instead of your visitors' browsers.
