Are you planning to print the JSON information?

I've been working on mastering JavaScript and decided to create a script that displays all public Facebook statuses related to a specific keyword. However, things aren't going as planned. You can find a sample URL where the JSON data is located here:

Unfortunately, the script isn't generating any results. Can anyone help me identify what might be wrong?

<input type="text" id="query" /><button>add</button><br />
<div id="results">

</div>

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
var url='http://graph.facebook.com/search?q=';
var query;
    $('button').click(function(){
        query=$("#query").val();
        $.getJSON(url+query,function(json){
            $.each(json.data,function(i,feed){
                 if(feed.type=='status') {
                        $("#results").append('<p>'+feed.message+'</p>');                 
                 }
            });
        });
    });
});
</script>

Answer №1

If you are trying to access data from an external URL, you may encounter the same origin policy which prevents it. However, using JSONP, supported by the Facebook API, can bypass this restriction. Simply add callback=? to your URL like this:

var url='http://graph.facebook.com/search?callback=?&q=';

(A similar approach is also used in the Twitter example mentioned in a previous comment)
