Learn more about it here.Īpart from directly making an Ajax call with JavaScript, there are other more powerful methods of making an HTTP call such as $.Ajax which is a jQuery method. If readyState is equal to 4, it means the request is done. The onreadystatechange property has two methods, readyState and status which allow us to check the state of our request. But how would we know if the request is done? In other words, how we can handle the responses with Ajax? If you view your browser console, it will return an Array of data in JSON format. We log the HTTP response to the console by using the XMLHTTPRequest.onreadystatechange property which contains the event handler to be called when the readystatechanged event is fired. Finally, we use the open() method to tie the HTTP method and URL endpoint together and call the send() method to fire off the request. To make an HTTP call in Ajax, you need to initialize a new XMLHttpRequest() method, specify the URL endpoint and HTTP method (in this case GET).
