Design And Realization Of Business System Based On Ajax

Currently, a web technology research Ajax hot. Ajax introduced asynchronoustransfer technology; promote local renewable pages, enhanced user experience. Contrast to the traditional web technology like Applet, flash, Ajax don't need specialized software to be used in most popular browsers, Ajax use XMLHttpRequest to send the asynchronous request.Ajax addresses the key technologies, including JavaScript, XMLHttpRequest, DOM, and XML. Through DOM JavaScript accesses request parameters information and Uses XMLHttpRequest to send the asynchronous request, servers handling of the Request, or to return to ordinary text XML, and then use JavaScript explains XML Browser, DOM updated and adopted relevant UI.We study Community Antenna Television business accepting system, which is a project of the information industries limited company of WuHan dongtai. This article study Ajax Web frame and design of Community Antenna Television business accepting system, in graduate thought, we study Ajax technology, Ajax conception and key technology, realization. Then, we use an open-source framework-Buffalo for the development of Ajax; Buffalo is a development Ajax frame by countrymen. Transmission basis having defined long-range invoking of Web in Buffalo, and general long-range transfer a marriage partner temporarily for a specific task entirely List-realization having arrived at local place, become the marriage partner who can be touched by JavaScript programming. The important module-BuffaloBinding in Buffalo enable JavaScript object binding to HTML element. This binding will be inviolable, and need to add some attribute that is not effect typesetting in HTML element. Buffalo enable JavaScript code can directly access Java methods, and eliminate all Ajax request-response cycle from the application code, the procedure takes only about business logic. So, we having been completed business accepting system successfully, and debugging is successful.
