9、或者说可操作性比较差，那么开发人员也许无法完全实现产品对消息管理的需求。因此，本文基于 JavaSeript设计了运行于 Web客户端的消息机制，实现了消息的可定制性，允许开发人员自定义消息类型及消息处理细节，允许自定义消息管理器容量，允许查询和处理历史消息；同时该机制也是组件化的，可以由 Web应用任意装载而不影响其独立性。 Message mechanism model Message mechanism is to manage the entire life cycle of the mechanism of the message, also called Message Manag

Norms for Message Manager, in 消息机制模型 消息机制是管理消息整个生命周期的机制，也可以称为消息管理器，主要分为 4个部分，图 1描述了消息管理器的主要组成部分和相互依赖关系。 基础管理 主要负责消息 的基础信息管理，包括类型管理、消息完整性的验证、消息内容的设置以及消息的状态处理这四个子模块。子模块之间的依赖关系如图1所示。例如，检验器是基于类型管理器工作的，检验器的工作完成后才能保证设置器所接受到的消息是结构完整的消息，所以检验器依赖于类型管理器，设置器依赖于检验器。 产生器 主要负责消息的产生。为避免使用者发送不规范消息 。规范”是针对消息管理器而言，在此设计消息管理器
