I had the same problem when I was working on asp.net Mvc webApi because cors was not enabled. I solved this by enabling cors inside register method of webApiconfig

First install cors from here then

   public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services

        var cors = new EnableCorsAttribute("*", "*", "*");
        config.EnableCors(cors);



        config.EnableCors();
        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }

JSONP or  JSON with padding  is a communication technique used in JavaScript programs running in web browsers to request data from a server in a different domain  something prohibited by typical web browsers because of the same-origin policy  JSONP takes advantage of the fact that browsers do not enforce the same-origin policy on script tags  Note that for JSONP to work  a server must know how to reply with JSONP-formatted results  JSONP does not work with JSON-formatted results   http   en wikipedia org wiki JSONP  Good answer on stackoverflow  jQuery AJAX cross domain       ajax           type   GET           url   http   www oxfordlearnersdictionaries com search english direct            data  q idiom           async true          dataType    jsonp       you may use jsonp for cross origin request         crossDomain true          success  function data  status  xhr                alert xhr getResponseHeader  Location

Place below line at the top of the file which you are calling through AJAX   header  Access-Control-Allow-Origin

User · Answer

I used the header  Access-Control-Allow-Origin       method but still received the CORS error   It turns out that the PHP script that was being requested had an error in it  I had forgotten to add a period     when concatenating two variables    Once I fixed that typo  it worked   So  It seems that the remote script being called cannot have errors within it

Is your website also on the oxfordlearnersdictionaries com domain  or your trying to make a call to a domain and the same origin policy is blocking you    Unless you have permission to set header via CORS on the oxfordlearnersdictionaries com domain you may want to look for another approach

User · Answer

If your website also on the oxfordlearnersdictionaries com domain  USE the following into the oxfordlearnersdictionaries com  htaccess file      Header set Access-Control-Allow-Origin

This also need    lt  php header  Access-Control-Allow-Origin

I think setting your header to Access-Control-Allow-Origin    would do the trick here  Had the same issue and I resolved it like that

We can not get the data from third party website without jsonp   You can use the php function for fetch data like file get contents   or CURL etc   Then you can use the PHP url with your ajax code    lt input id  idiom  type  text  name    value    placeholder  Enter your idiom here  gt   lt br gt   lt button id  submit  type    gt Submit lt  button gt   lt script type  text javascript  gt    document  ready function            submit   bind  click  function            var idiom     idiom   val              ajax               type   GET               url   get data php               data  q idiom               async true              crossDomain true              success  function data  status  xhr                    alert xhr getResponseHeader  Location                                             lt  script gt    Create a PHP file   get data php   lt  php   echo file get contents  http   www oxfordlearnersdictionaries com search english direct       gt
