1. Achieve better user experience through proper Ajax application;
2. Transfer some of the previous work of the server to the client, which is beneficial to the client's idle processing power to process, reduce the burden on the server and bandwidth, and thus achieve the purpose of saving the ISP's space and bandwidth rental costs.
2. Citation
Jesse James Garrett, who first proposed the concept of Ajax, believes that: Ajax is the abbreviation of Asynchronous JavaScript and XML. Ajax is not a new language or technology, it is actually a combination of several technologies in a certain way to play their respective roles in a common collaboration, it includes:
·Use XHTML and CSS for standardized rendering;
·Use DOM for dynamic display and interaction;
·Use XML and XSLT for data exchange and processing;
·Use XMLHttpRequest for asynchronous data reading;
·Finally, use JavaScript to bind and process all data;
