JSONP will allow you to do cross-site calls. See jQuery docs on that matter.
The concept is simple: instead of doing a normal Ajax call, jQuery will append a <script> tag to your <head>. In order for this to work, your JSON data needs to be wrapped in a
function call.
Your server needs to send information in such way (PHP example):
$json = json_encode($data);
echo $_GET['jsonp_callback'] . '(' . $json . ');';
Then, you can use jQuery to fetch that information:
$.ajax({
dataType: 'jsonp',
jsonp: 'jsonp_callback',
url: 'http://myotherserver.com/getdata',
success: function () {
// do stuff
},
});
