By using Javascript to manipulate DOM elements to refresh pages and reorganize data, rely on CSS to provide a consistent interface for applications, use XMLHttpRequest objects to communicate with the server asynchronously, submit requests in the background and get the latest data. Javascript defines business rules and processes, applications get data from the server in the background through XMLHttpRequest objects, and change the appearance of the interface through CSS and DOM.

Note:

1. Ajax is not only a Javascript, but a combination of technologies.

2. XMLHttpRequest communicates with the server to obtain data asynchronously in the background.
