I've seen this question asked several times, but the solutions aren't working. At this link, there's a nameless JSON object. I'm trying to get access to the data in the object. This is what I've tried so far:

$.getJSON is returning different errors. I read that adding "&callback=?" to the url would stop the "Access-Control-Allow-Origin" error, which worked, but then I ran into the "Unexpected token :" error. The JSON data looks correct to me, though.
I also tried doing this:
<!DOCTYPE html>
<html>
<head>
<script src="jquery-latest.min.js"
type="text/javascript"></script>
</head>
<body>
</body>
</html>
<script>
var jsondata = {}
$(document).ready(function() {
url = //removed to prevent line wrap
$.getJSON(url + "&callback=?",
function(data) { jsondata = data; } );
});
</script>
It produced the same unexpected token error. Any ideas?
