In what year was ajax released?

ajax was released on February 18, 2005. AJAX stands for "Asynchronous JavaScript and XML" (asynchronous JavaScript and XML technology), which refers to a set of browser-side web development technologies that combine multiple technologies. The concept of Ajax was proposed by Jesse James Jarrett.

Jesse James Garrett (English: Jesse James Garrett) is a designer in the field of user experience design, the founder of the web experience design company Adaptive Path, and a When using a browser to browse web pages; the name of the concept of asynchronous update technology "AJAX" that reduces the need to consume resources sent by the server when updating content on the page.

History of ajax development:

In the 1990s, almost all websites were implemented by HTML pages, and the server needed to be reloaded to process every user request. Web page. This processing method is not efficient. The user experience is that all pages will disappear and then be reloaded. Even if only a part of the page elements change, the entire page must be reloaded. Not only the changed parts must be refreshed, but also the parts that have not changed. This will increase the load on the server.

This can be solved with asynchronous loading. In 1995, the first version of the JAVA language was released, and the Java applets (JAVA applets) released subsequently implemented asynchronous loading for the first time. The browser exchanges data with the server by running Java applets embedded in the web page without having to refresh the web page. In 1996, Internet Explorer added the iframe element to HTML to support partial refresh of web pages.

Around 1998, the Outlook Web Access team wrote the first component that allowed client-side scripts to send HTTP requests (XMLHTTP). This component originally belonged to Microsoft Exchange Server and quickly became part of Internet Explorer 4.0[2]. Some observers believe that Outlook Web Access was the first successful business application to use Ajax technology, and it became the lead for many products, including Oddpost's webmail product. However, in early 2005, many events made Ajax more widely accepted. Google uses asynchronous communication in its famous interactive applications, such as Google Discussion Groups, Google Maps, Google Search Suggestions, Gmail, etc. The term Ajax was coined by the article "Ajax: A New Approach to Web Applications", whose rapid spread increased people's awareness of the use of this technology. In addition, support for Mozilla/Gecko makes the technology mature and easier to use.
