Hmm.

Perhaps so, but the j/s produced by CGI::Ajax for this script fills a
screen even without any line-breaks and formatting, and it would be eons
before I could write anything like that. Needless to say I don't have
the remotest idea what it's doing.
with the tiny (~15k) jQuery library loaded, all the javascript you would
have to write would be something like this (assuming you use rm=runmode
in CGIApp)
function validateNHSOwithAjax(myInput){
$('#someHTMLContainer').load(
'myWebApp.cgi',
{
rm : 'validate_nhso',
itemToValidate : myInput
});
}
This will neatly and reliably make the Ajax request and place the result
from your runmode where you want it on the HTML page. Come to think of
it, there are a couple well thought-out jQuery validation plugins
available, one of which uses Ajax.
If you set the perl sub to
sub validate_nhso{ return 'Fred' ;
}
what happens?
Predictably, and disappointingly:
Content-Type: text/html; charset=ISO-8859-1 Fred
Aargh. Well that's not one I can recall running into :-(
