【正文】 mation management。 關(guān)鍵詞 ：消息管理； JavaScript； Web應(yīng)用 中圖分類號： 文獻標志碼： A Introduction In most Web applications, the munication between the client and server message management remains a unilateral mitment by the server, the user and the web application developers who have brought a lot of restrictions. If the user needs to reproduce the history is limited to server request processing the request, if the request has been cleared by the server, or simply not kept, then the user can not reproduce。因此，本文基于 JavaSeript設(shè)計了運行于 Web客戶端的消息機制，實現(xiàn)了消息的可定制性，允許開發(fā)人員自定義消息類型及消息處理細節(jié)，允許自定義消息管理器容量，允許查詢和處理歷史消息；同時該機制也是組件化的，可以由 Web應(yīng)用任意裝載而不影響其獨立性。子模塊之間的依賴關(guān)系如圖1所示。規(guī)范”是針對消息管理器而言，在此設(shè)計消息管理器the design of the message manager generates this message unified interface, ie the message generator to ensure that messages are generated from the interface Message Manager can be verified by the norms messages. Dispatcher If the message is the message manager generates a message output interface, then the dispatcher is the receiver of the message interface. Dispatcher receives a message on the one hand to provide external access 121, on the one hand, after receiving the message, according to the message header information distributed to the designated server. Server group Web application server is not here referred to the server, but for the purposes of message processing server messages are working on the client system. Server group can contain multiple servers, from a design perspective different servers to handle different functional applications of messages, and the server is not static and is used by the developer to dynamically add the Message Manager management. 產(chǎn)生消息的統(tǒng)一接口，即消息產(chǎn)生器，以保證從此接口產(chǎn)生的消息都是消息管理器可以通過驗證的規(guī)范消息。服務(wù)器組可以包含多個服務(wù)器，不同的服務(wù)器從設(shè)計上講是為了處理不同功能應(yīng)用的消息，并且服務(wù)器不是靜態(tài)的，是由開發(fā)人員在使用消息管理器時動態(tài)添加管理的。每個消息服務(wù)器的子模塊之間都是相互獨立的。 2) Using the server group provides custom server interface, you can customize the server message queue length, the message storage capacity, as well as message processing approach: 的處理中再次存儲； 3)消息處理器循環(huán)的從消息隊列讀取并根據(jù)消息的內(nèi)容執(zhí)行相應(yīng)的處理，處理細節(jié)可以由消息管理器的使用者(Web應(yīng)用開發(fā)人員 )定制。如上節(jié)所述。 2) flexibility, autonomy by the Web application developers customized to meet a variety of message types and message processing for different needs。其不足之處在于沒有提供優(yōu)先級的處理，需要在消息隊列中加入按優(yōu)先級排序的
