【摘要】 以网络为载体的教学形式被认为是网络时代的新的教学方式,正在迅速发展。网络自主学习平台是一个以覆盖一定区域的计算机网络为载体,将该区域学生资源和丰富教学资源整合一体的支持服务体系。W eb2.0技术可以消除传统HTTP通信模式中对表单的依赖,从而实现快速而轻量的异步通信。阐述如何利用AJAX引擎构建一个框架以支持全新的W eb应用,实现了浏览器直接与后端服务的异步通信。在设计和实现中充分考虑了系统的安全性、透明性、好用性、完备性等特点,并对其关键问题做出深入研究,为今后同类系统的设计、开发和实现提供了一个详细的参考模型。更多还原

【Abstract】 The network-basing teaching has been considered as the new form of teaching,and is developing rapidly.Network independent studying platform is a support service system,which combines regional student information with rich teaching resources.WEB2.0 can eliminate the dependence of sheet in traditional HTTP communication mode,so quick and light asynchronous communication can be achieved with it.Building the architecture to support completely new Web applications with AJAX technology is expatiated.The asynchronous communication directly between explorer and back end service is implemented.In the design and implementation of this system,several issues such as security,system transparency,ease of use,and completeness are taken into consideration.We made in-depth study of its key issues,and provided a detailed reference models for future similar systems design,development and implementation.更多还原
