What year was Ajax released?

Ajax was released on February 18, 2005. AJAX stands for "Asynchronous JavaScript and XML" and refers to a set of browser-side web development technologies that integrate multiple technologies. Ajax was coined by Jesse James Jarrett.

Jesse James Garrett is a designer in the field of user experience design, founder of web experience design company Adaptive Path, and coined the name "AJAX," an asynchronous update technology that reduces the amount of server resources required to update content while browsing the web.

History of Ajax:

In the 1990s, almost all websites were implemented as HTML pages, and the server had to reload the page for each user request. Such a treatment is inefficient. The user experience is that all pages disappear and reload, even if only a part of the page elements change, the entire page must be reloaded, not only to refresh the changed parts, but also to refresh the unchanged parts. This will increase the burden on the server.

This can be solved by asynchronous loading. Java Mini programs (Java applets) were first loaded asynchronously in 1995, when the first version of the JAVA language was released. Browsers exchange data with servers by running Java applets embedded in web pages without having to refresh the web pages. In 1996, Internet Explorer added iframe elements to HTML to support partial page refresh.

Around 1998, the Outlook Web Access team wrote the first component that allowed client-side scripts to send HTTP requests (XMLHTTP). This component was originally part of Microsoft Exchange Server and quickly became part of Internet Explorer 4.0[2]. Outlook Web Access is considered by some observers to be the first successful commercial application to incorporate Ajax technology, and to be a leader in many products, including Oddpost's Web mail products. However, in early 2005, a number of events made Ajax popular. Google uses asynchronous communication in its famous interactive applications, such as Google Discussion Groups, Google Maps, Google Search Suggestions, Gmail, etc. Ajax was coined by Ajax: A New Approach to Web Applications, and its rapid spread raised awareness of the technology. Additionally, Mozilla/Gecko support has allowed the technology to mature and become easier to use.

Use XHTML+CSS to express information;

Use JavaScript to manipulate DOM (Document Object Model) to perform dynamic effects;

Manipulate data using XML and XSLT

Asynchronous data exchange with web servers using XMLHttpRequest or the new Fetch API;

Note: AJAX is distinct from RIA technologies such as Flash, Silverlight, and Java Applet.

At this point, I believe that everyone has a deeper understanding of "what are the applications of Ajax". You may wish to actually operate it! Here is the website, more related content can enter the relevant channels for inquiry, pay attention to us, continue to learn!
