This article shows you why Ajax is used. It is concise and easy to understand. It will definitely make your eyes shine. I hope you can learn something from the detailed introduction of this article.

The main reasons for using Ajax

1. Achieve a better user experience through appropriate Ajax applications;

2. Transfer some of the previous server burden work to the client, which is conducive to the idle processing capacity of the client to process, reduce the burden on the server and bandwidth, and thus achieve the purpose of saving ISP space and bandwidth rental costs.

Jesse James Garrett, one of the earliest proponents of Ajax, said:

Ajax stands for Asynchronous JavaScript and XML.

Ajax is not a new language or technology, it is actually several technologies combined in a certain way to play their respective roles in a common collaboration, it includes

Standardized rendering using XHTML and CSS;

Dynamic display and interaction using DOM;

Data exchange and processing using XML and XSLT;

asynchronous data reading using XMLHttpRequest;

Finally, bind and process all the data with JavaScript;

Ajax works by adding an intermediate layer between the user and the server, asynchronous user actions and server responses. Not all user requests are submitted to the server, such as some data validation and data processing are handed over to the Ajax engine itself to do, only to determine that new data needs to be read from the server and then submitted to the server by the Ajax engine.

That's why Ajax is used. Have you learned anything? If you want to learn more skills or enrich your knowledge reserves, please pay attention to the industry information channel.
