Ajax is a programming language that allows the updating of specific sections of content on a web page, without the need to completely reload the page.<\/p>\n<p>The term Ajax was first used by Jesse James Garret in 2005, in his publication &#8220;Ajax: a New Approach to Web Applications&#8221;.<\/p>\n\n<h2>Ajax Applications<\/h2>\n<p>With Ajax, web applications can send data from a server and retrieve it asynchronously (loading from the background), without interfering with the display and behavior of the existing page. By decoupling the data exchange layer from the presentation layer, Ajax allows web pages, and by extension web applications, to dynamically change content without needing to reload the entire page. Data can be retrieved using the &#8220;XMLHttpRequest&#8221; object. Despite the name, <a href=\"https:\/\/www.arimetrics.com\/en\/digital-glossary\/xml\">xml<\/a> is not required (JSON is often used in the AJAJ variant), and requests do not have to be asynchronous.<\/p>\n<p>Ajax is not a technology, but a group of technologies. <strong>HTML <\/strong>and CSS can be used in combination with it. <strong>JavaScript<\/strong> and the &#8220;XMLHttpRequest&#8221; object provide a method for asynchronously exchanging data between the browser and the server to avoid loading the page completely.<\/p>\n<h2>Frequently asked questions about Ajax<\/h2>\n<div class=\"geo-faq-block\">\n<details class=\"geo-faq-item\">\n<summary>What does Ajax mean in digital marketing?<\/summary>\n<p>Ajax refers to the concept described in this glossary entry: Definition: The acronym of Ajax stands for Asynchronous JavaScript and XML, or Javascript and XML Asynchronous.
