AJAX is a concept, an idea and not a programming language that is used for asynchronous data retrieval at the client server without the need of refreshing the page. AJAX is a set of web development techniques to develop client-side server applications. After the development of AJAX, it has been considered as the future of web applications. The plus point of AJAX is that it carries out the procedure in the backend whereas with no interference at the frontend.
Benefits of Using Ajax
User Experience is improved
The first and the foremost important advantage of using AJAX is improvement of user experience. AJAX has the ability to update webpages without interfering the front end. This makes the browser more responsive and ultimately helps to increase user experience.
Added User Productivity
AJAX has object oriented functions in its script which leads to added productivity rather than the resentment and discontent. Its enrichment can be identified by the very fact that important websites like Google and Yahoo also have incorporated AJAX in their developed programs, applications and servers. Though adding some more features in AJAX can make it surpass other developed techniques.
Bandwidth Usage Reduced and Speed Increased
AJAX only care for the data that is necessary so it reduces the burden on bandwidth and enhances the internet speed. In this way not only better speed can be enjoyed but also increased responsiveness and better interactivity can be cherished.
AJAX is compatible with almost all browsers as well as it is compatible with most of the web languages like PHP, ASP.Net, J2EE, etc. and so on.
Server Hits/Network Load Has Been Reduced
Ajax has literally managed to reduce the server hit or network load drastically. It is only possible because of the asynchronous data send and asynchronous data retrieval.
Navigation becomes Easier
AJAX has made it possible to make the navigation even easier. Now the user won’t have to use the traditional and standard front and back buttons of the browser.
What Advances Have Been Made To Ajax?
The use of both JSON and JQuery has added more advancement in AJAX with good programming practices.
Where Ajax Should Be Used?
AJAX finds its usability in web applications that don’t require data retrieval by refreshing the whole page rather they only need some small sized information to be sent and retrieved over the server without refreshing the whole page. Some of the examples where AJAX can be used are;
- Form Validation and Data Validation,
- Filtering Data in Dropdowns and List-boxes,
- Surveys And Polls,
Text Hints and Autocomplete boxes, etc.
