The design of website based on Ajax technologe
-- Design and implementation of online map online photo album
 
Abstract This article introduced constructs the Web website using Ajax group of technologies, realizes the map examination and the photo album browsing system method and the process in NET the platform, the content including seven parts: The first part introduces this technology in the domestic and foreign research present situation and the topic research background and the significance; Second part to Web2.0 synopsis and Ajax application and traditional Web application main difference; the third part to the Ajax essential technology, why uses, who is using as well as its development frame and the MVC overhead construction has made the introduction as well as the Ajax existence insufficiency and the flaw has made the simple introduction; The fourth part is to Net the system frame, the characteristic, how the development kit as well as do Ajax and Net the technology provide the asynchronous data transmission and the switching scheme essential technology using the network platform, with using the XMLHttpRequest object, Javascript, DOM, XML, CSS realizes Ajax in ASP.NET; Fifth part to system demand analysis including function demand performance demand movement environment demand as well as system plan determination and appraisal; he sixth part of system design simply introduced the design thought and the main design procedure including the system contact surface design, main function module chart; The seventh part of detailed design including the database design, the concrete function module realization, the map detailed information examination, is the actual development system research, through the map examined the system and the photo album browsing system example constructed the Web website using the Ajax technology the realization principle and the realization process and has expounded the concrete realization process and the system module transfer relations. The realization system has reduces the server the burden, the reduced user psychology and the actual standby period, brings the better user experience, the frugal space and the wide band rents the cost, may transfer exterior data, does not need to download the plug-in unit or the script, further promotes the page to present with the data separation
