jQuery.ajax call to Twitter succeeds but returns null for Firefox
- by Zhami
I've got code that makes a simple get request to Twitter (search) using jQuery's ajax method. The code works fine on Safari, but fails on Firefox (3.6.3). In the Firefox case, my jQuery.ajax parameters 'success' method is invoked, but the supplied data is null. (In Safari, I receive a boatload of JSON data).
My ajax call is:
$.ajax({
url: 'http://search.twitter.com/search.json?q='+searchTerm,
dataType: 'json',
async: true,
beforeSend: function(request) {
window.console.log('starting AJAX request to get Twitter data');
},
success: function(data, textStatus, request) {
window.console.log('AJAX request to get Twitter succeeded: status=' + textStatus);
callback(data);
},
error: function(request, status, error) {
window.console.log('AJAX request to get user data --> Error: ' + status);
errback(request, status, error);
}
});
Firebug shows Response headers:

The HTTP status is OK (200), the Conetnt-Type is properly application/json, and the Content-Length of 2126 (gzip'd) implies data came back. Yet Firebug shows the Response to be empty, and a test of the supplied data shows it o be 'null.'
I am aware of a similar post on Stack Overflow:
http://stackoverflow.com/questions/1188976/jquery-get-function-succeeds-with-200-but-returns-no-content-in-firefox
and from that would assume this problem is possibly related to cross-domain security, but... I know there are many JS widgets and whatnots that ajax get data from Twitter. Is there something I need to enable to allow this?
