Cross Domain Facebook getJson jQuery not bringing back data

Is there any reason at this doesnt work:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script type="text/javascript">
        $(document).ready(function() {
            var url = "https://graph.facebook.com/search?q=cinema&type=place&center=37.76,122.427&distance=1000";
            $.getJSON(url, function(data) {
                alert(data);
            });
        });
</script>

I should point out, that it doesnt return anything, not that its bringing back the wrong results,开发者_运维问答 none are returned.

is it because it's cross domain or not?

Thanks

Cross-domain requests require using JSONP. Either add a callback= URL parameter (if the web API supports it) or use jQuery.ajax with the dataType: "jsonp" parameter (search the jQuery.ajax documentation for "dataType").

Try putting in an error argument in the function (function(data,error,er) and alert these as well to try and capture the problem.
