Design And Implementation Of Ria Framework Based On Web 2.0

In recent years, the requirement for Web Performance from Internet has been becoming higher and higher along with the concept of Web 2.0. To show RIA front end, many companies and communities released their products. It has enriched the products of Internet with various RIA frameworks. User-centered design is infiltrated into a variety of Internet applications.This paper will propose to research and establish a solution of AJAX RIA framework cross-browser by using JavaScript technology. In this paper,first of all analysis of the concept of Web2.0 and thinking of the RIA,it's the framework for the design theory of reference. And then more in-depth studies of the JavaScript and AJAX technology,and the existing framework of the popular JavaScript RIA comparative analysis,based framework to provide technical support.Finally,discusses the design and build a framework for the process and the problems encountered. This framework for a company-specific products,as well as application-specific needs of the development scene,it has a relatively strong pertinence and ease of use. In addition to the framework such as DOM (Document Object Model) selection,event binding,style rendering,document manipulation encapsulated,but also based on the framework provided the core product-style UI components. In late stage development, we made a big change and reconstruction,particularly in the implementation of CSS selector,we have done a lot of research work to improve the framework for search DOM performance so that we can provide an easy to use,good performance JavaScript RIA framework.
