[removed] True form reset for hidden fields

Question

Unfortunately form.reset() function doesn\'t reset hidden inputs of the form. Checked in FF3 and Chromium.

Does any one have an idea how to do the reset for hidden f

Answer 1

Create a button and add JavaScript to the onClick event which clears the fields.

That said, I'm curious why you want to reset these fields. Usually, they contain internal data. If I would clear them in my code, the post of the form would fail (for example after the user has entered the new data and tries to submit the form).

[EDIT] I misunderstood your question. If you're worried that someone might tamper with the values in the hidden fields, then there is no way to reset them. For example, you can call reset() on the form but not on a field in the form.

You could think that you could save the values in a JavaScript file and use that to reset the values but when a user can tamper with the hidden fields, he can tamper with the JavaScript as well.

So from a security point of view, if you need to reset hidden fields, then avoid them in the first place and save the information in the session on the server.
