I have this code:

<script src=".7.2/jquery.min.js"></script>
<script>
    $(document).ready(function() {
        $.getJSON('', function(fbResults) {
            document.write(fbResults.cats[0].title);
        });
    });
</script>

How can I change this code:

<script>
    $(document).ready(function() {
        $.getJSON('', function(fbResults) {
            document.write(fbResults.cats[0].title);
        });
    });
</script>

for it to work as JSONP ... Is this totally different?

• Is the data offered from the server as JSONP? – user1106925 Commented Aug 11, 2012 at 19:07
• There's just JSON data on the server – Satch3000 Commented Aug 11, 2012 at 19:17
• 3 Then it won't work as a JSONP request. JSONP is basically just a <script> request. The response must have the data wrapped in a function call, like my_func({"foo":"bar"}). Then when the script arrives, assuming there's a function named my_func, that function is invoked passing the data into it. Some servers let you specify the function name, and they'll return the JSONP response, but this behavior must be established on the server. – user1106925 Commented Aug 11, 2012 at 19:25

Actually, you just have to add ?callback=?, jQuery does the rest.

$(document).ready(function() {
    $.getJSON('http://example.com/api/get_cats?callback=?', function(fbResults) {
        document.write(fbResults.cats[0].title);
    });
});
