Rick,
You could use Ajax, but it might be simpler to use JavaScript
validation. The jQuery validation plugin that Daemach pointed you to
would be an example of that. I wrote a validation plug-in myself that I
use for a client, and it works pretty well. I think the other plug-in is
maybe more feature-full than mine is, but that's neither here nor there.
For your calculator, I'd definitely suggest JavaScript validation. Give
a holler if you need help with that. I've not used the big jQuery
validation plugin, but I can show you the one I wrote, and maybe it
would suit your needs.
Cheers,
Chris

First question I have is about which type of validation I need:
Ajax or non-Ajax?
Here's my current jQuery code... I believe it would be classified
as "Ajax", however, it doesn't mention "Ajax" anywhere, so I'm unsure...
function CalculateMortgage(){
var Params = {};
// select all inputs of type text
$("input:text").each(function(){
Params[$(this).attr("name")] = $(this).val();
});
// "post" the form. The Param object mimics form fields
$.post("Mortgage_Calculation.cfm", Params,
function(data){
// this is the processing function.
// append what you get back to the element
with ID = Result after clearing its contents
$("#Result").empty().append(data);
}
);
}
I have three form fields to validate:
Principal: Validate for entry / Validate that entry is numerical after $ ,
. are all stripped from entry.
Interest: Validate for entry / Validate that entry is numerical
Years: Validate for entry / Validate that entry is numerical
There are so many examples on
http://bassistance.de/jquery-plugins/jquery-plugin-validation
that I'm not sure which one is most appropriate. I usually use RegEx to
validate the principal entry, too.
So... two questions...
Do I need the Ajax validation plug-in?
Which one of the examples would be best, or is it just a matter of style
preference. ( I usually put
a general message at the top of the form stating that there are errors.
Then I put specific messages
above each form field.)
Thanks for any assistance and guidance!
Rick

Alright... now I've got this working very well.
The only problem I have now is validation.
