Ajax: Requesting Data and Retrieving Responses

Course details

Rather than a singular technology, Ajax, or Asynchronous JavaScript and XML, is a collection of technologies that enables web pages to make server requests without having to reload the page. You can use Ajax to create asynchronous web applications that provide a faster, more user-friendly experience. In this course, you will learn how to use the XMLHTTPRequest object to send data requests and retrieve data from the server in the form of text, XML, and JSON responses.
