javascript - Changing getJSON to JSONP

Question

I have this code:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script>
    $(document).ready(function() {
        $.getJSON('http://example.com/api/get_cats', function(fbResults) {
            document.write(fbResults.cats[0].title);
        });
    });
</script>

How can I change this code:

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

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

Answer 1

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);
    });
});
