【摘要】：HTML5是移动设备、云计算和网络时代的一种网站和应用程序开发新概念，是互联网的下一代标准，是构建以及呈现互联网内容的一种语言方式。HTML5是将Web由一个内容展现的“工具”变成一个成熟的应用“平台”。HTML5扩展新增了交互能力、多媒体呈现能力、云端服务集成能力与本地处理能力。它不只是增强了交互性和页面表现能力，在语义特性、连接特性、多媒体特性、本地存储特性、三维图形及特效特性、设备兼容特性和CSS3等方面，都发生了根本性的变化。 论文在研究HTML5技术的基础上，从实时数据传输、离线应用和存储、云计算下的新型WebOS上入手，在前端效率机制和Web应用模式方面进行研究。 论文在表述了研究背景及意义、综述了国内外研究现状、阐述了Web实时数据传输技术、本地存储和应用以及云计算后，对所确立的目标展开了研究，并进行了基础性和验证性实验，概括起来取得了以下的研究： 提出了一个基于WebSocket的实时同步协同Web表单模型，一个B/S模式下的实时协同Web模型-CoModel，给出Web表单的实时协同问题的解决方法。通过基础和验证性实验从中发现WebSocket的前端效率机制，传输效率以及在网络流量方面的优势。 提出了一个基于HTML5的Web离线应用架构模型，给出web应用在断网脱机或网络状况不佳的情况下使用的解决方法。在OFF-ORDER上实现和应用了基于HTML5的Web离线应用方案，并从实例中发现了此方案的可行性和优越性，并且通过实验验证了OFF-ORDER模型的可行性和优越性。 提出了一种云计算在网络断网或不佳的情况下，，基于HTML5的可离线WebOS云计算模型。通过引入HTML5的离线应用和本地存储等功能，给出云计算Web操作系统离线工作的解决方法。最后通过HTML5技术构建一个基本的Web操作系统，展现了在云计算下新型Web操作系统的基本模式和功能。
[Abstract]:HTML5 is a new concept of website and application development in the era of mobile devices, cloud computing and network, and is the next generation standard of the Internet. HTML5 is a language that transforms Web from a content presentation "tool" to a mature application "platform". The HTML5 extension adds interactive and multimedia rendering capabilities. Cloud service integration capabilities and local processing capabilities. It not only enhances interactivity and page expression, but also changes radically in semantic features, connection features, multimedia features, local storage features, 3D graphics and special effects features, device compatibility features and CSS3. Based on the research of HTML5 technology, this paper starts with real-time data transmission, offline application and storage, new WebOS in cloud computing, and studies front-end efficiency mechanism and Web application mode. This paper describes the background and significance of the research, summarizes the current research situation at home and abroad, expounds the Web real-time data transmission technology, local storage and application, and cloud computing, and carries out the research on the established objectives. The basic and confirmatory experiments have been carried out, and the following researches have been made: a real-time synchronous cooperative Web form model based on WebSocket and a real-time cooperative Web model based on B / S mode CoModel, are proposed. The solution to the real-time collaboration problem of Web form is presented. The advantages of WebSocket front-end efficiency mechanism, transmission efficiency and network traffic are found through basic and confirmatory experiments. This paper presents a Web offline application architecture model based on HTML5, and gives the solution of web application when the network is offline or the network condition is not good. The off-line application scheme of Web based on HTML5 is implemented and applied in OFF-ORDER, and the feasibility and superiority of this scheme are found out by an example, and the feasibility and superiority of OFF-ORDER model are verified by experiments. In this paper, an off-line WebOS cloud computing model based on HTML5 is proposed. By introducing the functions of offline application and local storage of HTML5, the solution of offline operation of cloud computing Web operating system is presented. Finally, a basic Web operating system is constructed by HTML5 technology, which shows the basic mode and function of the new Web operating system in cloud computing.
