2 actions in onsubmit

[minaozoptics]

Hi,

I have prepared a form with frontpage.

Before submitting the form I want the user to bu sure that he ha
completed it exactly. Sometimes people click ENTER button just t
continue the fill next part of the form but when we clic
ENTER,unfortuna tely, the form is submitted directly.

So I have written a function verify with javascript.

As following it works correctly:

onsubmit="retur n verify()"

So that the user needs to accept that he is OK to submit the form.

But when I added some required parts in the form that should b
verified the first fuction verify is no longer active.

So how can I verify both required parts in the form and that the use
is OK to send the form?

Thanks so muc

Did you have to? Frontpage is a plague upon the Web, spitting out badly
malformed HTML. It would be quicker to write the page by hand, than to gut
the trash that Microsoft products like Frontpage and Word add.

Unless you're well-versed in HTML, I'd advise you learn to code by hand
first and validate your pages.

To my knowledge, I've never encountered a browser that switches fields
with the Enter key. I've always used Tab. Users should know their browser
well enough to know which method to use. If you are really worried about
accidental submissions - for example, the form initiates some critical
action - add an intermediary page that asks for confirmation. Don't rely
on Javascript.

You could use:

<form ... onsubmit="retur n verify() &amp;&amp; validate()">

which would normally be written as

return verify() && validate();

If verify returns false (the user cancels), the evaluation will
short-circuit, and the form won't be submitted. If the user does confirm,
then validate must also return true in order for the submission to proceed.

However, I think that the confirmation should be moved to the server, if
you really feel it's necessary, just as server-side validation should also
occur with client-side used just to speed things up.

Hope that helps,
Mike
