parse a field before posting to server

Question

Hello

I have a field on my form, which I'd like to parse before sending to a Web server. Is it possible by using C functions provided by the web server?

I mean, suppose I have parse_field() function written in C, and the web server knows it and can call, so I do something like <% parse_field() %> on the page, the function shouls take the current contents of the field as an argument and return some parsed value, which will be POSTed to the server.

Is it possible, or not by all means? Or it is better to do with JavaScripts function (but I'm not very good with JS though :( )? Thanks !

Answer 1

I'd suggest JavaScript, since it is server sided. Maybe you are trying to validate something? Have a look at this: http://flowplayer.org/tools/demos/validator/index.html

Answer 2

Is this classic ASP?

I wouldn't rely on Javascript for validation. You can't assume that everyone has JS enabled. You should implement server-side validation for graceful degradation, and then implement JS for client-side validation.
