Error: Unable to load the JSON file from the specified URL due to an XMLHttpRequest restriction

I've been struggling to read a JSON file from a URL and display it. Despite searching through multiple forums, I can't seem to fix the issue.

Here's the URL:

The error message I'm encountering is: XMLHttpRequest cannot load.

Below is the code snippet I've been using:

$.getJSON("http://webapp.armadealo.com/home.json", function(data){
alert(data);
});

I've attempted adding parameters to the URL like:

&callback=?

and trying to make it a JSONP request – unfortunately, no luck. I've also included the following meta tag:

<meta http-equiv="Access-Control-Allow-Origin" content="*" />

But still no success.

Is there something that needs to be configured on the server-side? If anyone has encountered this problem before and found a solution, please help me out! Thank you!

To overcome the security restrictions preventing cross-domain AJAX requests, you can utilize a workaround known as JSONP (more info, example)

Implement the following code for your AJAX request:

$.ajax({
    url: 'http://webapp.armadealo.com/home.json',
    type: 'GET',
    jsonpCallback: 'myCallback',
    dataType: "jsonp",
    success: function(data) {
        console.log(data);
    }
});

To make this method effective, ensure to enclose the JSON data in parentheses and prepend the callback name like so:

myCallback({ ... JSON ... })

EDIT: It seems you have already attempted using JSONP. Nevertheless, you can give the above code snippet a shot to see if it resolves your issue. ;)
