XMLHttpRequest cannot load is not allowed by Access-Control-Allow-Origin

Question

I'm trying to get access to education.com API data. However, I keep receiving an error the error states:

XMLHttpRequest cannot load http://api.education.com/service/service.php?f=schoolSearch&key=mykey&sn=sf&v=4&city=Atlanta&state=ga&Resf=json. Origin is not allowed by Access-Control-Allow-Origin.

My code is the following:

$(function(){
    $.getJSON('http://api.education.com/service/service.php?f=schoolSearch&key=mykey&sn=sf&v=4&city=Atlanta&state=ga&Resf=json', 
    function(data) {
        console.log(data);
    });
});

Can someone help me please?

An article on Cross Domain AJAX issue a while back here:

CROSS DOMAIN AJAX REQUEST WITH JSON RESPONSE FOR IE,FIREFOX,CHROME, SAFARI – JQUERY

The easiest way to handle this if you have control of the responding server is to add a response header for:

Access-Control-Allow-Origin: *

This will allow cross domain AJAX. In PHP you'll want to modify the response like so:

<?php header('Access-Control-Allow-Origin: *'); ?>

you can just put Header set Access-Control-Allow-Origin * setting on apache conf or htaccess file it just work like a charm

Important Note:
The wildcard is going to allow any domain to send requests to your host. I recommend replacing the asterisk with a specific domain that you will be running scripts on.
