You're trying to make a cross domain ajax call, which is forbidden by the browser's Same Origin Policy.

Assuming your remote url allows for JSONP requests, and assuming you're using JQuery > 1.5, you can simply add crossDomain:true to your $.ajax() params.

You can have a look at the following (ref : http://api.jquery.com/jQuery.ajax/)

xhrFields(added 1.5.1)Map

A map of fieldName-fieldValue pairs to set on the native XHR object. For example, you can use it to set withCredentials to true for cross-domain requests if needed.

$.ajax({
   url: 'a_cross_domain_url',
   xhrFields: {
      withCredentials: true
   }
});

crossDomain(added 1.5)

Default: false for same-domain requests, true for cross-domain requests

If you wish to force a crossDomain request (such as JSONP) on the same domain, set the value of crossDomain to true. This allows, for example, server-side redirection to another domain
