how to bypass Access-Control-Allow-Origin?

I'm doing a ajax call to my own server on a platform which they set prevent these ajax calls (but I need it to fetch the data from my server to display retrieved data from my server's database). My ajax script is working , it can send the data over to my server's php script to allow it to process. However it cannot get the processed data back as it is blocked by `"Access-Control-Allow-Origin"` I have no access to that platform's source/core. so I can't remove the script that it disallowing me to do so. (P/S I used Google Chrome's Console and found out this error) The Ajax code as shown below: $.ajax({ type: "GET", url: "http://example.com/retrieve.php", data: "id=" + id + "&url=" + url, dataType: 'json', cache: false, success: function(data) { var friend = data[1]; var blog = data[2]; $('#user').html("<b>Friends: </b>"+friend+"<b><br> Blogs: </b>"+blog); } }); or is there a `JSON` equivalent code to the ajax script above ? I think `JSON` is allowed. I hope someone could help me out.
