Uncaught SyntaxError: Unexpected token JSON

Question

Hi Every one I'm trying to get this json file from a web service from this website : "http://172.20.192.218:8080/DC_Local/rest/datacorrelation?type=/soccer/football_team&limit=20&callback=?"

However I'm getting this "Uncaught SyntaxError: Unexpected token" But I dunno whats wrong.

this is my code for calling the json file :

var pts = [];
    $.getJSON("http://172.20.192.218:8080/DC_Local/rest/datacorrelation?type=/soccer/football_team&limit=20&callback=?", function(data) {
        //JSON.parse(data);

        $.each(data, function(i,v){
            pts.push([v.topic, v.audience.length]);
        });
     });

and this is my json file I'm trying to get :

{"data":[{"id":"/en/arsenal_fc","topic":"Arsenal F.C.","audience":[],"type":"/soccer/football_team"},{"id":"/en/ajax_amsterdam","topic":"Ajax Amsterdam","audience":[],"type":"/soccer/football_team"},{"id":"/en/az_alkmaar","topic":"AZ Alkmaar","audience":[],"type":"/soccer/football_team"},{"id":"/en/as_roma","topic":"A.S.

You do not need the JSON.parse() call. Not sure, whether you used it or not, when you got the error. — Sirko

Is it because you're trying to iterate over an array but you're actually getting an object back? Does iterating over data.data work? — Tim Croydon

Your URL has callback=? in it which tells jQuery this is a cross domain jsonp request. Is server returning json or jsonp ? If it is only json and is cross domain it won't work and would be reson for error — charlietfl

You have to write $.each(data.data, function(i,v){ instead of $.each(data, function(i,v){.

Sample:

<!DOCTYPE html>
<html>
    <head>
        <title>Add many Elements</title>
        <script src="jquery.js"></script>
        <script>
            $(document).ready(function() {
            var dataString = '{"data":[{"id":"/en/arsenal_fc","topic":"Arsenal F.C.","audience":[],"type":"/soccer/football_team"},{"id":"/en/ajax_amsterdam","topic":"Ajax Amsterdam","audience":[],"type":"/soccer/football_team"},{"id":"/en/az_alkmaar","topic":"AZ Alkmaar","audience":[],"type":"/soccer/football_team"},{"id":"/en/as_roma","topic":"A.S.

                var pts = [];
        var data = JSON.parse(dataString);

        $.each(data.data, function(index,data){
            pts.push([data.topic, data.audience.length]);
        });
            });
        </script>
    </head>
    <body>
        <div class="testDiv">
            <div class="testDivPos"></div>
        </div>
    </body>
</html>

Your first sentence does not really make sense to me. Bot variants seem identical.
Sorry, I meant to the second example should have said *'$.each(data, function'
