Explanation of AJAX
AJAX (Asynchronous JavaScript and XML) is a technique used to send and receive data from a server asynchronously without refreshing the entire page. In this application, the loadDoc function initiates an asynchronous request to fetch the cd_catalog.xml file using the XMLHttpRequest object.
The open method of the XMLHttpRequest object is used to configure the request, specifying the HTTP method (GET) and the file to be fetched (cd_catalog.xml). The onload event handler is triggered once the request is successfully completed, at which point the response is passed to the myFunction function for further processing.
The myFunction function parses the XML response using the responseXML property of the XMLHttpRequest object. It extracts specific elements such as ARTIST, TITLE, and YEAR from the XML structure and dynamically updates the HTML table to display the CD collection.
By leveraging AJAX, this application ensures seamless data updates without requiring a full page reload, enhancing user experience and performance.
