There is a "validate" attribute to the "action" element in
struts-config.xml. You set it to true or false.

Hi, Erik,
I got an idea. I can insert another action before
the actual action be executed. And use javascript
change a hidden property before executing the
added
action, then I can do what i want to do in the
added action. What do you think? I will try it
later.
Thanks for your help!

JavaScript can change the action URL on the fly.
For
example:

However, I'm not sure how compatible this type of
thing will be with the
Struts form tag. I've never tried it. I'm
surprised
others aren't
speaking up because the "multiple submit" problem
comes up a lot. If you
search the archives for "multiple submit buttons"
you might find other
ideas.

Hi,Erik,
I think that helps. I have another question.
Besides the "action" attribute in html:form, is
anywhere else we can specify another "action"
corresponding the submission of javascript?
Thanks.

There may be other ways or better ways, but one
thing you could do is
vary the action URL. You could have the same
action
class serving
slightly different action mappings, some with
validation set to true and
some with validation set to false.
I did what you are trying to do in a non-Struts
Servlet app, and there I
just used a query string parameter to indicate
which type of submit was
happening (but I didn't have to worry about
getting
past the validator).
Remember that JavaScript can change the value of
a
field (including a
hidden field) before it submits the form.
Also, another technique for conditionally using
the
validator is to turn
automatic form validation off, override the
validate method in your
ActionForm, but there simply invoke the validator
manually just as
Struts would have done with automatic validation.
This gives you a
chance to insert a switch before invoking the
validator.
Probably there are others on the list who know a
lot more about this
than me and might have a better idea. Hope that
helps.

The problem is, when the form is submitted, it
will be validated according to the validator. then
error will occur since the user didn't intend to
submit and he/she didn't fill other required
fields.
And in my "acion" program, I don't know how to
tell whether it was submitted by "javascript" or
by
the "submit" button.
Any idea about that?
Thanks.

Thank you for the hint. I will try.

a way to do it. But, you'd have to have all list
data downloaded to the
client's browser (could be undesirable depending
on list size), so you
may want to rethink that approach once you
figure
out how to do it.
Obviously it can be done using ordinary
programming on the server side
(JavaScript can resubmit the page when the first
select's value is
changed, and you can change the collection to be
displayed in the second
select before you resend the HTML).

Hi, all,
I have two html:select as below:
---------------------------------------------------
labelProperty="label"/>
labelProperty="label"/>
--------------------------------------------------------
when user choose item2 from s1, I want to
change
the collection in s2
from "c2" to "itemC". How can I do that?
Thanks in advance!
