Overview
The AJAX technology is available in native mode in WEBDEV and in the PHP sites developed with WEBDEV.
What is AJAX and what are its benefits?
AJAX (Asynchronous Javascript and XML) is used to refresh the data modified in an HTML page without having to redisplay the entire page. For example, if some elements found in the page displayed (content of the basket, characteristics of a product, list of cities, map, ...) are modified, only these elements will be refreshed. The server does not have to send the entire page onto the computer of the Web user.
This technology presents several benefits:
  • the server is less used. Therefore, it can support an important number of simultaneous connections.
  • the information that circulates is less bulky.
  • the transmission time is shorted.
  • the display is immediate and without visual effect for the Web user.
AJAX can be used at two different levels in a WEBDEV site:
Note: The former browsers do not support the AJAX technology (Internet Explorer 5.5 and later, FireFox 1.0 and later, Netscape 7 and later, Opera 8 and later, Safari 1.2 and later, ...). AJAXAvailable is used to find out whether the AJAX technology is supported by the current browser. If a process that is using the AJAX technology is run on a browser that does not support this technology, the process is run "as if" it did not use the AJAX technology (the entire page is refreshed for example).
