I am trying to make ajax POST request but always get error as "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at "myURL". This can be fixed by moving the resource to the same domain or enabling CORS." and "No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access." I am able to post data to server but can't get response from server.
