Improvement of PRG Pattern by Using Ajax Technology

Abstract:

The study discusses the fusion technology of PRG pattern and Ajax and its applications. After analyzing the natures and shortcomings of PRG pattern, it introduces improvement of PRG pattern by using Ajax technology, and proposes three patterns: A-P pattern, A-PRG pattern and A-PG pattern. These patterns can make full use of the characteristics of Ajax technology, which can send asynchronous requests to the server and partially update page, and solve the shortcomings of PRG pattern. Finally, the implementation technology of the patterns in JSF application is presented; the applicable scenarios and constraints of the patterns are elaborated.
