Ajax Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource

I'm writing a simple site that takes as input an idiom, and return its meaning(s) and example(s) from Oxford Dictionary. Here's my idea:

I send a request to the following URL:

http://www.oxfordlearnersdictionaries.com/search/english/direct/?q=[idiom]

For example, if the idiom is “not go far”, I'll send a request to:

http://www.oxfordlearnersdictionaries.com/search/english/direct/?q=not+go+far

And I'll be redirected to the following page:

http://www.oxfordlearnersdictionaries.com/definition/english/far_1#far_1__192

On this page, I can extract the meaning(s) and the example(s) of the idiom.
Here's my code for testing. It will alert the response URL:

<input id="idiom" type="text" name="" value="" placeholder="Enter your idiom here">
<br>
<button id="submit" type="">Submit</button>
<script type="text/javascript">
$(document).ready(function(){
    $("#submit").bind('click',function(){
        var idiom=$("#idiom").val();
        $.ajax({
            type: "GET",
            url: 'http://www.oxfordlearnersdictionaries.com/search/english/direct/',
            data:{q:idiom},
            async:true,
            crossDomain:true,
            success: function(data, status, xhr) {
                alert(xhr.getResponseHeader('Location'));
            }
        });
        
    });
});
</script>

The problem is I've got an error:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://www.oxfordlearnersdictionaries.com/search/english/direct/?q=by+far. This can be fixed by moving the resource to the same domain or enabling CORS.

Can anybody tell me how to resolve this please?
Another approach is fine too.

Solution 1:

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.

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'));
  }
});

Solution 2:

Place below line at the top of the file which you are calling through AJAX.

header("Access-Control-Allow-Origin: *");

Solution 3:

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.

<input id="idiom" type="text" name="" value="" placeholder="Enter your idiom here">
<br>
<button id="submit" type="">Submit</button>
<script type="text/javascript">
$(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'));
            }
        });

    });
});
</script>

Create a PHP file = get_data.php

<?php
  echo file_get_contents("http://www.oxfordlearnersdictionaries.com/search/english/direct/");
?>

Solution 4:

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.
