The way you used
jsonp is wrong.Please check below mentioned link for more info.
$('document').ready(function() {
var pm_url = 'http://twitter.com/status';
pm_url += '/user_timeline/stephenfry.json';
pm_url += '?count=10&callback=photos';
$.ajax({
url: pm_url,
dataType: 'jsonp',
jsonpCallback: 'photos',
jsonp: 'callback',
});
});
function photos (data) {
alert(data);
console.log(data);
};
Basic example of using .ajax() with JSONP
I hope this will help to you.
