Ajax This stuff is not a new technology, but a mixture of Asynchronous Javascript XML and other technologies.
The explanation mentioned in the original text:
Ajax Isn't A Technology. It's Really Several Technologies, Each Flourishing In Its Own Right, COMING TOGETHER IN POWERFUL New Ways. Ajax Incorporates:
standards-based presentation using XHTML and CSS; dynamic display and interaction using the Document Object Model; data interchange and manipulation using XML and XSLT; asynchronous data retrieval using XMLHttpRequest; and JavaScript binding everything together
Ajax's mode is different from traditional web mode lies in Ajax plus a user response layer in the browser side, which makes people feel like a desktop program in the web interface, rather than submitting it as a traditional web interface => Enter the page, then submit => Load page .Who's using ajax concept is similar, we find a few sites to see: Gmail, they mentioned Gmail, I have been used in Gmail, I have used many mistakes, I will not mention it. This, let's take a look at http://maps.google.com/, this Google's map query station, it seems to be able to use the US map, the interface is dragging maps, and the page does not need to be reloaded, this feeling It's almost like desktop applications, I will take a look at the famous picture blog site Flickr: http://www.flickr: http://www.flickr: http://www.flickr: http://www.flickr.com/flickr website, it can be said that Flash should be the easiest to implement Ajax, the user experience is the best One, the above picture is the picture album of Flickr, from LOAD, the picture can be dragged to the corresponding album, which has broken the traditional interface hook selection album and then click Submit update mode, of course, this is just one of them. Multi-picture processing in Flickr is blocked with Flash, so that users can operate their hands, do whatever you want, cool!
