How Ajax Works?
Ajax isn’t just a single technology; rather it is a set of technologies. Ajax is a combination of:
XMLHttpRequest object (used to swap data asynchronously with the web server)
CSS (used to add style to the information)
XML (frequently used as a format to transfer data)
Advantages of Ajax:
There are three main advantages of using Ajax in website:
Greater interactivity: This is the main reason why a lot of developers and programmers are using AJAX in their websites. AJAX permits simpler and faster interaction between the visitor and website since webpages are not reloaded for content to be shown.
Simpler Navigation: AJAX applications on a website can be created to permit simpler navigation to visitors compared to making use of the classic back and forward button on a web browser.
Greater Speed: The primary goal of Ajax is to increase the speed, efficiency and user friendliness of a web application. A good instance of Ajax is the movie rating system on the website. The visitors rate movies and their personal ratings will be saved to the database without waiting for the webpage to reload.
Why and Where Ajax is used
Ajax should be used anyplace in a website where a few amounts of information need to be stored in a web server or retrieved from the web server without submitting back the whole page. A great example of applying Ajax is validating data on a save action.
Other great example would be to include suggestions and auto complete text boxes dynamically during the time of filling up a form. For example the user types a couple of letters to find a name and a list of all names which begin with those characters appears below. A callback is created to the web service which will obtain all names that start with these letters. This is really a wonderful function that would not be possible without Ajax.
