"Troubleshooting the issue of Wikipedia's AJAX call not functioning properly

var url = 'http://en.wikipedia.org/w/api.php?action=opensearch&format=json&limit=15&search=' + search;
var ourRequest = new XMLHttpRequest();

ourRequest.open('GET', url);

ourRequest.onload = function() {
  var data = JSON.parse(ourRequest.responseText);
  console.log(data);
};
ourRequest.send();

Could anyone please explain why the parsed data is not showing up in my console?

Answer №1

To ensure your request works correctly, make sure to include an additional parameter in your url variable - origin=*. Once you add this parameter, your code should run smoothly.

I've made a modification to the url variable so that it includes the necessary origin parameter for the Wikipedia API request.

document.getElementById('do-search').addEventListener('click', search);

function search(){
  var search = document.getElementById('search').value;
  var url='http://en.wikipedia.org/w/api.php?action=opensearch&format=json&limit=15&origin=*&search='+search;
  var ourRequest = new XMLHttpRequest();

  ourRequest.open('GET', url);

  ourRequest.onload = function() {
    var data = JSON.parse(ourRequest.responseText);
    document.getElementById('results').innerHTML = data;
  };
  ourRequest.send();
}
<input id="search" type="text">

<button id="do-search">Search</button>

<div id="results"></div>

Answer №2

After some trial and error, I managed to successfully implement this code in my project.

$.ajax({
url: url,
jsonp: "callback",
dataType: "jsonp",
success: function(data) {
  console.log(data);
 }
 });
