基于国产操作系统的办公支撑关键应用技术的机制与原理

The Mechanism and Principle of Key Application Technology of Office Support based on Domestic Operating System

笔者首先对国产操作系统和相关的办公业务系统的现状进行了简单的分析,阐述了当前我们面临的IE等不同浏览器的兼容性问题。然后具体分析了基于浏览器的业务系统的基本原理,建立于三层架构之上的浏览器业务系统由于解析文件流的方式不同,导致了浏览器不兼容的问题,并以IE和Firefox为例,细致分析了两种浏览器解析文件流的具体方法。在阐述两者的差异之后,提出了系统业务迁移所需要的关键技术,简要介绍了XML以及HTML语言后,详细介绍了两种方法,其一是使用各个浏览器都支持的方法将访问元素节点的方法封装,让浏览器在访问文件时直接调用封装好的方法;其二是利用接口和XSLT文件将XML文件转化为能够在Firefox等浏览器上正常显示的XHTML文件。在第二部分简述了以上技术的不足之处后,在最后提出了基于云端的业务系统的发展状况,并指出当前应致力于制定跨平台的系统业务模块开发标准。

The author first describes the status quo of domestic operating system and related office business system,and expounds the compatibility problem of IE and other browsers.And then specifically analyzed the basic principles of the browser-based business system,built on the three-tier structure of the browser business system due to the analysis of file flow in different ways,resulting in the browser is not compatible with the problem,and IE and Firefox,Detailed analysis of the two browsers to analyze the specific flow of documents.After elaborating the difference between the two,this paper puts forward the key technology needed for system business migration.After introducing XML and HTML language briefly,two methods are introduced in detail.One is to use the methods supported by each browser to access the elements The method of wrapping the node allows the browser to call the encapsulated method directly when accessing the file.The second is the use of interfaces and XSLT files will be converted to XML files in Firefox and other browsers on the normal display of XHTML files.After summarizing the shortcomings of the above technology in the second part,this paper puts forward the development of the cloud-based business system at the end,and points out that it is necessary to develop the cross-platform system business module development standard.
