the term ajax has multiple uses, although it is not part of
the dictionary prepared by the Royal Spanish Academy (RAE). This
could be, for example, the name of a famous Dutch soccer team.
The Amsterdamsche Football Club Ajax, which is usually
named Ajax, was founded in 1900. The
team competes in the First Division of the Dutch tournament,
where it has won more than thirty trophies. He even became a European champion
on several occasions.
Johan Cruyff, Frank Rijkaard, Marco
van Basten, Ronald and Frank de Boer, Dennis
Bergkamp, Patrick Kluivert, Clarence Seedorf, Marc
Overmars and Edgar Davids are some of the great
footballers who have worn the Ajax shirt.
When the concept appears written in capital letters (AJAX),
it is an acronym that, in Spanish, refers to the expression "Asynchronous
technique used in the field of computing for the development of
interactive web applications. The AJAX applications have the
particularity to run in the browser Internet, simultaneously
communication between the browser and the server takes place in the background.
It is important to understand that AJAX is not a single technology,
but a combination of several, and that it has existed for many years. Among the
HTML and CSS.
Thanks to such an implementation we can achieve results of an impossible
dynamism with HTML alone, for example. The secret is that, unlike an old
website, where once a page is finished loading on the client's computer, it no
longer downloads information from the server, AJAX is able to maintain constant
communication without completely refresh the page, as if it were a silent update of
Let's see below the explanation of each part of this acronym:
* "Asynchronous" refers to the fact that from the time the
client requests information from the server until the response
arrives, the page does not stop working, but rather that the experience
continues normally and, in general, the user can continue interacting with the
rest of the the elements, even canceling your request (for example, closing a
pop-up box showing the communication status). As soon as the exchange between
the server and the client is finished, a “behind the scenes” response is
prepared, which finally generates the desired change in the content (for
example, going from the “News” section to “Store”);
type response, it analyzes its content and finally updates
the DOM (the «Document Object Model», that is, the interface
with which the representation is possible of web documents, XML and XHTML);
* To make the request to the server, the
client uses the XMLHttpRequest or XHR API. An API ("Application Programming
Interface") is a series of methods used to specify the communication rules
between two parties. It is important to note that the response does not have to
be in XML, but can be in any format.
With tilde in the first A (Ájax), the
term refers to two different characters from the mythology of Ancient
Greece: Ájax (or Áyax) the
Great, the son of Peribea and Telamón; and Ajax (or Ajax) the
Lesser, a descendant of Oileo.
A genus of plants, a model ships, and a brand of
chemicals used for cleaning also share the designation of ajax.
