Dynamic Form Submission
I want to create a form that has two different actions. The user will have
a button to READ information in from the database and a button to SAVE
information into the database after modification. I currently use Validator
to validate my forms and when the user clicks on the READ button then
Validator takes over and gives the user errors. I dont want the form to be
validated when the user is attempting a READ. I only want the form to be
validated if the user is attempting to do a SAVE. Unless anyone has a
better solution (which I hope someone does), I have decided that I need to
create two action classes. One that will handle the read logic without
going through validation and one that will handle the save logic and go
through the validation. My question with this solution is how do I
elegantly provide this functionality on the jsp? Do I put the SAVE submit
button within one form and the READ submit button within another form and
have different actions associated with each form? Or, is there a better
way?
Thanks,
Christopher Kwiatkowski

You can use the same Action and the same ActionForm, but you can map two
different action mappings in struts-config.xml. Set validation to "true"
on one and "false" on the other.
Hope that helps,
Erik

First, I assume that you are using path mappings for Validator.
You can use two separate forms as you suggested; however, if you don't
want to duplicate form fields and it makes more sense from a usability
perspective to have a single form--you can change the action for the
form on the fly using JavaScript like the following:
--------------------------------------------------------------------
<script>
function swapAction(control) {
formAction = document.getElementById("empForm").action;
if (control.checked)
newAction = '<html:rewrite page="/CreateEmployee.do"/>';
else
newAction = '<html:rewrite page="/UpdateEmployee.do"/>';
document.getElementById("empForm").action = newAction;
}
</script>
<html:form styleId="empForm" action="/UpdateEmployee">
New Employee: <html:checkbox property="create"
onclick='swapAction(this)"'/><br />
… rest of the page

Hello,
How about using a DispatchAction triggered by a
Parameter, let's say 'buttonSelected', which would be
Either insert/read/delete etc....
In ur validation you check for the value of that parameter in order
To perform validation...
Hope this helps

I want to create a form that has two different actions. The user will
have
a button to "READ" information in from the database and a button to
"SAVE"
information into the database after modification. I currently use
Validator
to validate my forms and when the user clicks on the "READ" button then
Validator takes over and gives the user errors. I don't want the form
to be
validated when the user is attempting a "READ". I only want the form to
be
validated if the user is attempting to do a "SAVE". Unless anyone has a

to
create two action classes. One that will handle the read logic without
going through validation and one that will handle the save logic and go
