I have the following code:

// Jquery Script

<script
  src="https://code.jquery.com/jquery-3.2.1.min.js"integrity="sha256-hwg4gsxgFZhOsEEamdOYGBf13FyQuiTwlAQgxVSNgt4="
  crossorigin="anonymous"></script>

// JS Script

$.ajax({
    type: "GET",
    url: "http://revistadesignmagazine.com/wp-json/wp/v2/posts",
    error: function (xhr, ajaxOptions, thrownError) {
      alert(xhr.status);
      alert(thrownError);
    }
}).done(function ( data ) {
  console.log(data);
});

When I make the call I get the following error:

"XMLHttpRequest can not load link The 'Access-Control-Allow-Origin' header has a value ' link ' that is not equal to the supplied origin. Origin 'null' is therefore not allowed access. "

How to receive the error-free call date and only display the title of the posts?

You probably need to add the Header to CORS on the server side (where json is generated in the url you posted). In C # for example, I use Response.AppendHeader ("Access-Control-Allow-Origin", "*");

If you have wordpress access, you can add it to the functions.php within the theme used: (I used this function with the wp-rest plugin too)

/**
* Add REST API support to an already registered post type.
*/
/**
 * Use * for origin
 */
add_action( 'rest_api_init', function() {

    remove_filter( 'rest_pre_serve_request', 'rest_send_cors_headers' );
    add_filter( 'rest_pre_serve_request', function( $value ) {
        header( 'Access-Control-Allow-Methods: POST, GET, OPTIONS, PUT, DELETE' );
        header( 'Access-Control-Allow-Credentials: true' );

        return $value;

    });
}, 15 );

If you do not have access, then you need to create a middleware, a server that requests and responds to the request, eg an application in node.js that when you hit a url, your api, get the data and return on the request you are making.

So: get to link - > hit the url link - > responds to the content of this url.
