I did some testing late last year, and the basic's are very simple:
The scary part is the javascript, which is only as huge because it
needs to care for two versions of internet explorer in addition to all
the rest:
<html>
<body>
<script type="text/javascript">
function ajaxFunction()
{
var xmlHttp;
try
{
// Firefox, Opera 8.0+, Safari
xmlHttp=new XMLHttpRequest();
}
catch (e)
{
// Internet Explorer
try
{
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
try
{
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e)
{
alert("Your browser does not support AJAX!");
return false;
}
}
}
xmlHttp.onreadystatechange=function()
{
if(xmlHttp.readyState==4)
{
document.myForm.time.value=xmlHttp.responseText;
}
}
xmlHttp.open("GET","/cgi-bin/time.cgi",true);
xmlHttp.send(null);
}
</script>
<form name="myForm">
Name: <input type="text"
onkeyup="ajaxFunction();" name="username" />
Time: <input type="text" name="time" />
</form>
</body>
</html>
This will enter the data gotten from "time.cgi" into the second input
field, whenever you type in to the first field. The cgi now only needs
to be this:
#!rev
on startup
put the short system date into temp
put "Content-Type: text/plain" & cr
put "Content-Length:" && the length of temp & cr & cr
put temp
end startup
That's it!
I learned most of my web stuff from w3schools.com, it's a very good,
and newbie friendly ressource.
have fun

PS: AJAX means Asynchronous JavaScript and XML, but i used totally
extreme plain text, so this is more like AJAP ;-)
PPS: if time.cgi where time.php (or, rev isn't always less lines):
<?php
echo Date("G:i:s");
?>

Can you explain this a little further. I am not proficient in CGI or
AJAX but am now 'forced' into learning JS, CSS, XML in order to put
a web based application together. I did not want to learn another
language either and have put this off as long as I can. But now I
must. So a newbie I am and feel lost in a bigger world than me.
Is there a real newbie way to learn how to integrate AJAX with REV?
I have been reading daily and have put my other projects on hold.
Thanks

on my agenda: take raw content (photos and text-caption files) and
build Highslide JS web objects for inclusion in web pages via SSI's
-- love doing <!include exec="someCoolRev.cgi" --> and then let
revolution do the work of building into that space on the page--
that is after all, what PHP is doing, but at 1/10th the speed of
Revolution on the same box/CPU...
