When the errors are returned at the top of the page are they supposed to be read automatically? I am coding JSP with the use of struts. I work at the United States Department of Agriculture.

You always need to validate on server side. Using only client-side validation opens you up to evil clients who can fiddle with your input information. Client-side is basically an add-on with added benefits, but server-side is a must.

My preference is to validate at the time of inputting the information. That way, once a user gets to the end, the form is correct and can be submitted.

Hello all.

I am seeking your thoughts on which type of form validation is preferred. A form with required fields (with proper notifications) can be validated server side when submitting the form or each field can be validated while completing the form.

With validation on submit, if there are errors, the form is refreshed with the focus returning to the top of the form where the errors are listed. When validating each field while completing the form, the user is notified of the error right away and focus is returned to the field.

In my opinion, both methods meet WCAG 2.0. However, keeping usability in mind, is there a preference to which method is used.
