Jquery Get json from remote host

I am gong to assume this page is not being served from the site that hosts the JSON.

You are attempting to make a cross-domain request, which most(?) browsers to do allow. You are encountering what is called the same-origin policy of the browser. It is a security measure built into the browser. It will not allow you to make an XHR request to a location that is not on the same origin as the requesting page.

There are a few ways around this:

1. Use a server-side proxy to make the request
2. use JSONP to make the request (See GBD's answer)
3. Look into CORS

You have cross-domain issue, so you need to use JSONP so change your jquery method as below

If the URL includes the string "callback=?" (or similar, as defined by the server-side API), the request is treated as JSONP instead.

$.getJSON("http://xx.xxx.xxx.xx/rest/user.json?jsoncallback=?",function(result){
  $.each(result, function(i, field){
    $("div").append(field + " ");
      });
    });
