For my ASP pages, I find that using JavaScript as much as possible to validate the form before it is submitted saves me a *lot* of work. If something is entered incorrectly and the problem is found after the page is submitted, I then have to put all of the values from that page into variables and insert server-side code into each HTML object to conditionally set that content as the default value for the object.
<br><br>With JavaScript for validation, you simply refuse to allow the page to submit when something is wrong. The user loses nothing if there is a problem repopulating a field, and there is no delay as the page reloads or refreshes. Plus, you don't need to have extra server-side code which re-creates the entire input page *or* moves on to the next step, depending upon the validity of the data.
<br><br>At least, that's my humble opinion from my several years' experience in developing in-house intranet applications professionally. Perhaps there are other environments or application types where others have found the opposite to be true. I'd be interested in hearing about them if so.

This is something I'm working into too. JavaScript is great for<br>"/front-data-evalutating/" and many other employments, but I try to keep<br>all the basic and necessary functions for my sites in standard html,
<br>doing "/real-evaluating/" in server-side scripting.<br><br>--<br>Flavio Gomes<br><a href="mailto:flavio@economisa.com.br">flavio@economisa.com.br</a><br><br>_______________________________________________<br>
