Ajax-based Web Application Framework And Practice

As the Internet has become more mature, Web applications featuring responsive user interfaces and maintainability capabilities have become increasingly popular. However, classic Web applications have generally exhibited problems such as slow performance and heavy network traffic. So, a new design for the web-Ajax appeared recently. Because Ajax minimizes traffic to the server by sending and requesting just the minimum amount of data needed, it can make Web-based applications more responsive, interactive, and customizable. In short, Ajax recreate the seamless user experience of most other desktop applications.At present, although there are many application frameworks for Ajax, but they only focus on the asynchronous process of Ajax and not take the client side and server side into together. So they are difficult to satisfy the entire process of Ajax application development. In this paper, we discuss the basic technology of Ajax and the theory of Design Patterns and Framework. And under the direction of the methodology of object-oriented and the theory of Design Pattern, we present an Ajax framework that we name it as Ajax Framework for .Net which take the client side and server side into together and can satisfy the basic process of Ajax application development and also have good flexibility and extensity. In this framework, client side and server side use JSON(JavaScript Object Notation) to exchange data. Compare to traditionally use XML to exchange data, it save the communication bits, so improve the communication efficiency.At last, we discuss how to use this framework to develop and realize the Ajax talk tool, and take this for example to introduce the works which need to do for developer who use this framework.
