The Study And Application Of Enterprise WEB Development Technique Based On AJAX

Web application systems are becoming increasingly popular for its feature of easy deployment and good maintainability and being able to provide rich user interface. With the state and enterprise and public institution's rapid development of information technology and the quantity increase of information, many problems are increasingly exposed in the traditional model of web applications, such as slower response speed and worse service performance. A new web development technology, Ajax, is becoming the hot spot of research and application in web application areas.Ajax adopts an asynchronous call model to locally refresh the web pages, in the way of"obtain data on-demand"to send data to the servers and accept data when required. As a result, network flow is reduced. The research of enterprise web development technique based on Ajax can make web applications faster real-time response speed,better interactivity and more convenient personalized service, which make users feeling like using desktop applications to use the web applications, and thus web applications'operating efficiency is enhanced.The enterprise web development techniques based on Ajax is studied in the paper, and used into the research and development of the network-based human resources management system. The main contents are as follows:Firstly, technological base of J2EE-based enterprise web application is mentioned. The paper explains the J2EE platform technology, MVC model and its addvanteges from the three aspects which are N-tier enterprise application platforms of J2EE and enterprise JavaBeans and the architecture of web application.Secondly, important technology Ajax is studied, which contains the concept of Ajax, and Ajax's working principle, key technology and development frameworks.Then how to apply Ajax into the MVC pattern on the J2EE-based web development platform is dicussed.Thirdly, the working principle and the application of DWR framework in network-based human resources management system are expounded. Functions like dynamic dropDownLists with data linkage and autowire-completion are implemented. According to application results, Ajax's pros and cons are commented.Finally, Ajax security is analysised and some relevant solutions are delivered.The study and application of enterprise web development technique based on Ajax shows that asynchronous call model and"obtain data on-demand"of Ajax decreases the burden of communication, and operating efficiency of web applicatons using Ajax is enhanced for its faster real-time response speed, better interactivity and more convenient personalized service.
