Question

I need to request a twitter search with jquery using twitter api. After read documentation I write this code:

  $.getJSON("http://search.twitter.com/search.json?callback=myFunction&q=stackoverflow");

   function myFunction(r) {
       console.log(r);
    }

search.json Failed to load resource> When the page is executed, Google Chrome show this error on Console:

XMLHttpRequest cannot load
http://search.twitter.com/search.json?callback=myFunction&q=stackoverflow.
Origin http://localhost/twitter is not
allowed by
Access-Control-Allow-Origin.
search.json Failed to load resource

what is the problem?

You need to write it a bit differently, like this:

$.getJSON("http://search.twitter.com/search.json?callback=?&q=stackoverflow", 
  function (r) {
    console.log(r);
});

To trigger JSONP it’s looking for explicitly callback=?, which isn’t in your named function version. To use the named callback, you’re better off going with the $.ajax() full version:

$.ajax({
  url: "http://search.twitter.com/search.json?q=stackoverflow",
  dataType: "jsonp",
  jsonpCallback: "myFunction"
});

function myFunction(r) { console.log(r); }
