Ajax Basics Tutorial (1)-ajax Introduction 1.8 Summary

The internet was initially just a link for researchers to share information, and today the Internet has grown enormously. The internet started with a simple text browser and static page, but now almost every company has a beautiful website, it is not easy to find a rough site. Who could have thought that one day people could study new cars online, or buy the latest king novels?

Developers of fat customer applications are suffering from deployments because they are eager to offload the web to the thousands of user machines they want to use. Over the years, there have been many Web applications, some dedicated, some requiring superb programming capabilities. Although these technologies have their own advantages in the user experience, none of these technologies enables thin client applications to reach the level of desktop applications. However, because it is easy to deploy, with a larger customer base and lower maintenance costs, this shows that although browsers have some limitations, they are still the preferred target platform for many applications.

Developers can use a number of tricks to circumvent the Internet's trouble limits. With a variety of remote scripting methods and HTML elements, developers can communicate asynchronously with the server, but the real cross-browser approach is possible until a mainstream browser provides support for the XMLHttpRequest object. Companies such as Google, Yahoo and Amazon are already ahead of us, and we can see that browser-based applications are also comparable to those of fat customers. With Ajax, you can take advantage of both: The code is on a server that you can control, and you can access an application that provides a rich user experience as long as the client has a browser.
