Ajax (Asynchronous JavaScript and XML) is a programming technology that allows Java-based Web ApplicationsProgramJava technology, XML, and JavaScript are combined to break the page overload paradigm.
Ajax is not a technology, it is not a software, and of course it is not your favorite team. You cannot download any available Ajax software or framework from your website. Ajax is a solution that integrates JavaScript, XML, XMLHttpRequest, and other technologies. It is called Asynchronous JavaScript and XML, Which is abbreviated as Ajax. Now you are using applications that use Ajax solutions, such as Gmail, Google Map, and Google suggestion.Source code, You will find the sourceCodeIt is completely composed of javasctip scripts, right?
In this solution, ecmascript, which is a javascript extension, is used to parse XML files. Therefore, it is also called (ecmascript for XML, E4X ). The introduction of this technology makes parsing XML in Javascript very simple.
If there is Asynchronization, there will naturally be synchronization. Our traditional network applications are officially based on synchronous transmission, and users send requests-> server logic processing-> servers respond to user requests to complete display. This is the complete process for a user to access an application or webpage. The user has gone through three waiting processes from making a request to the end of the request. It seems that this is an unchangeable reality in the traditional solution. However, is it true that AJAX not only provides us with a brand new idea, but also challenges traditional solutions.
