Re: date validate

[Bill Meecham <BMeecham@xxxxxxxxxxxxxxxxxxxx>]

I agree.  To lessen network traffic as much validation as possible should be
done in the browser so that each event is checked.  There are at least a
couple of ways to do that.  One is with script, the other is to validate
onblur or onchange with a form submit into an iFrame.  Using the latter, a
common validation routine can verify that the input for the field is correct
and respond to any errors as they're made instead of submitting the full
form and then seeing every error on the form.
 
Validation can be done on the server but I'd rather have it done as data is
entered than validating every input on the form after submit.

I belive that validation *must* be made in the server, and it is very 
convinient to do it also in the browser, javascript is an exelent tool 
for that.  Also, javascript can help filling the form, suplying 
reasonable defaults and offering dinamic options. BUT the validation in 
the browser is easy to disable, so, it is mandatory to validate in the 
server.
