 If,
as an RPG programmer, you happen to dabble
with any sort of Web interface, you’ve
most likely heard of Asynchronous JavaScript
and Extensible Markup Language (XML),
better known as AJAX. At the moment,
there’s quite a buzz about AJAX,
with opinions varying from “another
flash in the pan” to “the
greatest thing since sliced bread.” As
usual, the truth probably falls somewhere
in between. But AJAX does have plenty
to offer RPG programmers who write programs
for the Web.
This article (the first of two) provides
an overview of AJAX and its background,
and it shows how to use AJAX in conjunction
with RPG Common Gateway Interface (CGI)
programs. When used in conjunction with
CGI programs, AJAX uses asynchronous
calls to “update” the page
while the user is working. So there is
no delay or “white page” while
the user waits for a response from the
server.
