基于JavaScript的动态Web应用系统设计

摘要

当前桌面动态Web应用系统存在移动设备屏幕小、带宽低、不方便输入等弊端,在工作中可能会出现布局混乱、功能失效的问题,用户体验性不好.为此,设计了一种新的基于JavaScript的动态Web应用系统,给出动态Web应用系统体系结构,其由用户层、JavaScript引擎层、Web服务层及数据层构成,介绍了系统总体结构和硬件架构.详细分析了S3C44BOX芯片,给出JTAG接口和RS 485通信模块的设计过程.实验结果表明,该系统加载性能和程序执行效率高,安全性强.%The current desktop dynamic Web application systems have the problems(such as chaotic layout and disabled function)at work and poor user experience due to the disadvantages of small screen of mobile device,low bandwidth and incon-venient input. Therefore a new dynamic Web application system based on JavaScript was designed. The system architecture of the dynamic Web application system is composed of the user layer,JavaScript engine layer,Web service layer and data layer. The overall structure and hardware architecture of the system are introduced. The S3C44BOX chip is analyzed in detail. The de-sign process of JTAG interface and RS 485 communication module is given. The experimental results show that the proposed sys-tem has high system loading performance,high execution efficiency,and strong security.
