jQuery $.get fails

I am using $.get to send and receive the response from my php file. When I visit get-ratings.php, it outputs the response normally. Then when I use jquery, it just fails completely.

These are the firebug logs

Even when I set my php file to just echo a simple line of text, it fails.

This is the jquery code I am using

        $.get("get-ratings.php", { ids:vidIds.trim(",") }, function(data){
            console.log("MADE IT: " + data);
        });

I am calling this code from a javascript file that is included into a different domain than the get-ratings.php is hosted on.

Ive tried using $.post and $.ajax and both failed as well.

Cross domain requests will generally fail. Use getJSON.

Cross-domain policy limitations... Modern browsers do not allow XHR requests to domains other than that the page is hosted on.

If you have access to the PHP file, you can use a technique like in JSONP: Instead of AJAX, make a new script element , set the path to the php file as a source and append the script element to the document. And then, in php file, wrap the output in a "javascript function".

var script = document.createElement('script');
script.type = 'text/javascript';
script.src = "get-ratings.php";
$("head").append(script);

Create a new js function

window.complete = function(data){
  //do your stuff here with data received;
}

and finally the php code

instead of just "echo $data", use

echo "complete('.$data.')";
