阐述了网上选座系统的基本工作原理,运用UML技术中的用例图模型化网上选座系统,并用时序图描述网上选座用例所包含的时序关系。实现中充分考虑动态服务器程序和SVG图形之间的良好协作。分别完成了放映厅座位的SVG图形设计、不同座位状态的图形标识和交互性的网上选座,并结合实例说明了动态的、图形化的剧院网上选座系统的实现。
The fundamental working theory of seat-picking on web is interpreted at first. The sequence diagram of the use case named seat- picking on web is described after the use case is given by the use of UML (united model language). The favorable collaboration relationship between SVG (scalable vector graphics)- and active server pages is taken into account in the process of the program design. Moreover, how to mark seats which have different status and the alternating seat-picking with clients is implemented step by step with the support of the SVG design of audience area. Finally an instance is given to explain the implementation of active and graphics seat-picking on web.
