I have only one form in my JSP.
My question was not clear that is why I explain agin my problem.
My problem is the following I have a form:
<html:form action="/setupLookupDispatchAction.do" method="GET">
- with hyperlinks:
<html:link page="/setupLookupDispatchAction.do" paramId="method"
paramName="call" onclick="document.forms[0].submit();">
- with buttons
<html:submit property="method" styleClass="myButton" ><bean:message
key="button.cancel"/></html:submit>
In the setupLookupDispatchAction I test the method parameter
public ActionForward execute() throws Exception
{
if ( request.getParameter( mapping.getParameter() ) == null )
{
...
}
}
The parameter is not null for hyperlinks and buttons but not for
a combo box.
In my JSP I have a combo box and I would like to update the form
when the selection change to do this I should pass a parameter
method which should be equals to update:
<script>
function updateForm(form) {
form.action='/myLookupDispatchAction.do?method=update';
form.submit();
return true;
}
</script>
<html:select onchange=updateForm(document.forms[0]);/>
I don't understand how it works.
In my setupLookupDispatchAction I test request.getParameter("method")
in the JavaScript I set the parameter for the action not the request
then I is normal that in the execute method this parameter is null.
It is probably not the best way to set action it will be better to use
hidden field.
Do you have an example for what I try to do ?
Thanks in advance

Do you have mutiple forms on the page? Your JS function takes an argument
which it ignores and always sets the action of 'myForm'.
Try debugging with a JS alert just before you submit, showing the action
value for your action.
Having said all that, I would set the method via a hidden field on your form
rather than modifying the action.
