Question

can any one please tell me why this jQuery function is not working. It raises no alert.

$.getJSON('http://api.twitter.com/1/statuses/user_timeline.json?',
  {
      screen_name: 'samajshekhar',
      count: '5',
  },
 function (data) {
      alert('hello world from twitter');
  });   

In fiddler i can see that expected JSON has been returned.

However when calling flicker’s api using the example code at jQuery documentation it gives an alert as expected

$.getJSON('http://api.flickr.com/services/feeds/photos_public.gne?jsoncallback=?',
  {
    tags: 'cat',
    tagmode: 'any',
    format: 'json'
  },
  function(data) {
   alert('hello world from flicker');   
  });

Here is the sample code on JS Bin

I tried even with facebook’s graph API still no alert

In sample code i tried getJSON calls to facebook,twitter,flicker and only the flicker’s call’s alert is raised.

Answer 1

You need to append a callback parameter to the url so that it becomes a jsonp call.

http://api.twitter.com/1/statuses/user_timeline.json?callback=?
