XForms技术在RIA中的应用

W3C制定的XForms标准为新一代的RIA应用提供了强大的支持。基于XForms标准的GUIXML 1.1版本充分利用了这一特点,成功地实现了内容与表现的分离,以及内容数据模型的建立和维护。 $$  随着XML的广泛应用,RIA环境下客户端内容数据一般都采用XML格式作为其存储和数据交换的格式。这种格式的内容数据有其本身的结构和语义信息,因此数据也更复杂更难以处理。GUI XML规范为了解决这种RIA中普遍存在的问题,对内容数据处理提出如下要求: 能够在XML格式的内容数据基础上定义内容数据模型,同时又不破坏原有内容数据的结构和语义信息。另一方面,面对RIA环境的特殊要求,在内容数据处理的基础上还需要增加一系列内容数据交互功能,例如,运行时数据的导入、网络传输以及内容缓冲机制等。 $$  HTML表单的出现在相当大程度上促进了当今的电子商务革命。但其本身在很多方面仍然存在着设计和功能上的不足。其中最重要的一点是HTML表单将数...  (本文共3页) 阅读全文>>
