AJAX - Asynchronus Javascript And XML Using JavaScript technology an HTML page can asynchronously make calls to the server from which it was loaded and fetch content that may be formatted as XML documents HTML content plain text or JavaScript Object Notation (JSON). The JavaScript technology may then use the content to update or modify the Document Object Model (DOM) of the HTML page.
