HTML
While developing AJAX applications, it's typical to design HTML markup for various things.
-
CSS
Although CSS isn't an immediate requirement for AJAX apps, it's used when designing interface features. Thereby, a profound knowledge of CSS will be really helpful in the longer run.
-
JavaScript
The heart of AJAX is the
XMLHttpRequestobject. Moreover, it's also customary to mutate the DOM via DOM methods, all of which are JavaScript APIs.
Course overview
AJAX is an acronym for Asynchronous JavaScript And XML, and a convenient name given to the set of technologies that make it possible to develop asynchronous client-slide applications.
AJAX allows HTTP requests to be made from within JavaScript and therefore update the contents of a page with the new requested page, all asynchronously. This means that page refreshes can be made without the need to reload the page. AJAX enables what we call refresh without a reload. AJAX is a client-side masterpiece and developing applications in it is a concern of many emerging websites.
It is important to realise the fact that AJAX isn't a programming language, neither a framework, nor a library. It is just an elegant name, given to the set of technologies that allow asynchronous communication with the server and help in working with the response received.
These technologies include, but aren't limited to, HTML for constructing a structure of the document, CSS to style it on the go, JavaScript to write a whole AJAX engine and interact with other APIs, HTML DOM to make dynamic changes to the document, and XML or JSON for exchanging data between the client and the server.
