$.getJson function not working

Question

var query1 = urlencode($('input[name="searchTerm"]').val()); //user1
$.getJSON('http://twitter.com/friends/ids.json?screen_name='+ query1 +'&jsoncallback=?', 
function(data){
$('content').append(''+data.length+'');
});

This is a simple code that gets the json data from the url

http://twitter.com/friends/ids.json?screen_name=Planemad&jsoncallback=?

(click url to view the json data)

The data looks like this:

[6014732,1717291,14049312,1000591,13,2384071,20,14071015,813286,7517052,14279711,....]

"data.length" should give me the number of users the specified user is following.

However it doesnt seem to work for some reason. Any help would be deeply appreciated.

Thank you.

Answer 1
