Based On The Front-end Efficiency Mechanism HTML5 And Web Application Model

HTML5is a mobile device, a Web site and application of cloud computing and the Internetage to develop new concepts. HTML5standard is the next generation of the Internet, is to buildand render the way a language Internet content. HTML5is to show the contents of the Webconsists of a "tool" to become a full-fledged application "platform." HTML5extends the abilityto add interactive, multimedia presentation capabilities, the ability to integrate cloud serviceswith local processing capabilities. It is not just enhances the interactivity and page performancecapabilities, semantic features, connectivity features, multimedia features, local storage features3D graphics and special effects features, the device is compatible and CSS3features, etc., haveundergone fundamental changes.Based on the study HTML5technology, from real-time data transmission, offlineapplications and storage, cloud computing WebOS these aspects, to study the efficiency of themechanism in the front and the Web application model.Presentation of research papers in the background and significance, summarized the currentresearch. Web thesis describes the real-time data transmission technology, local storage andapplications, cloud computing. Paper launched on the target established by the study and carriedout the foundation and validation experiments. Made a research paper summed up as follows:Firstly, proposes a WebSocket-based real-time synchronous collaborative Web Formsmodel. This model is a real-time collaborative Web model-CoModel a B/S mode is used tosolve the problem of real-time collaborative Web form. Through basic and confirmatoryexperiments which found that the efficiency of the tip WebSocket mechanism, the transmissionefficiency and the advantages in terms of network traffic.Then made offline Web application architecture model based on HTML5, the poorcondition of the network to solve the case. Implementation and Application of Web applicationsbased on HTML5offline in the OFF-ORDER. And found that the feasibility and superiority ofthis program from the instance. Experiments demonstrate the superiority of OFF-ORDER model.Finally, a cloud computing network in case of disconnection, the WebOS-based HTML5offline cloud computing model. By introducing HTML5local storage and offline applicationfunctions, solve the problem of cloud computing and Web operating system can not work offline.Finally, build a basic Web operating system through HTML5technology, used to show the newWebOS basic modes and functions.
