newbie question - setting form parameter in Javascript
Hi,
I have an HTML form with Submit and Cancel buttons, and a drop down list, which when clicked submits the form. I use Javascript to submit the form when the dropdown list is clicked.
I have a property called "action" defined in my ActionForm class that identifies the Submit and Cancel buttons in the HTML form. When the drop-down is clicked, I would like to set the value of this "action" property to "Lookup".
My Javascript function is given below:
################
<SCRIPT language="JavaScript">
function submitForm(form)
{
form.action.value="Lookup";
form.submit();
return true;
}
#################
and I invoke this function in my HTML form as shown below:
#########################
<html:select property="crn" onclick="submitForm(this.form)">
<html:option value="Test" selected>Test</html:option>
</html:select>
###########################
But, the value of the property "action" is not set to "Lookup".
Any help would be greatly appreciated.
Thanks,
Shyam

I think I see where you are going....try setting the form action instead:
<SCRIPT language="JavaScript">
function submitForm(form) {
document.frm.action="lookup.do"; // <--Change this to not be hard-coded
form.submit();
return true;
}
</SCRIPT>
<form name="frm" action="?" method="GET">
<input type="hidden" name="action" value="">
<select name="crn" onclick="submitForm(this.form)">
<option value="Test" selected>Test</option>
<option value="Test2">Test2</option>
</select>
<br>
<input type="submit" name="action" value="Submit">
</form>

Re: newbie question - setting form parameter in Javascript
Posted by Mark Lowe <ma...@talk21.com>.
check out dispatch actions..
you can have multiple execute methods with dispatch action ...
Your Action class extends DispatchAction instead of action (check the
docs)
public final ActionForward submit(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
...
}
public final ActionForward lookup(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
...
}
in struts config the parameter attibute need to know the name of the
parameter your about to send, the value of which is your execute method
name..
<action path="/processForm" type="com.sparrow.struts.MyAction"
scope="request" parameter="action">
...
and then in jsp
<html:link page="/processForm.do?action=lookup">
<html:link page="/processForm.do?action=submit">

Re: newbie question - setting form parameter in Javascript
Posted by Shyam A <st...@yahoo.com>.
James,
Thanks for your mail. I guess I need to elaborate a little bit. My HTML form can be submitted in 2ways.
1. Clicking the "Submit" button.
2. Clicking the drop-down
Clicking the drop-down triggers a different action than clicking the "Submit" button.
Selecting a value in the drop-down would submit the form and populate some of the other fields in the form. This is done before the "Submit" button is clicked. So, I need to distinguish the action of clicking the drop-down from clicking the "Submit" button and I called it "Lookup".
Both actions would be identified with a single property in the ActionForm class - action.
eg:
<html:submit property="action" value="Submit"/>
I would like to set this "action" property value to "Lookup" on clicking the drop-down using Javascript. I guess a hidden field would not serve the purpose as I already have "action" property defined for the Submit button.
Look forward to your help/suggestions.
Thanks,
Shyam

Re: newbie question - setting form parameter in Javascript
Posted by James Mitchell <jm...@apache.org>.
You will need to create a hidden field named "action", with a value of
"Lookup":
<html:hidden property="action" value="Lookup"/>
My question to you is....why "Lookup"? What does that have to do with your
form?
Here's a sample:
<SCRIPT language="JavaScript">
function submitForm(form) {
form.action.value="Lookup";
form.submit();
return true;
}
</SCRIPT>
<form name="frm" action="?" method="GET">
<input type="hidden" name="action" value="">
<select name="crn" onclick="submitForm(this.form)">
<option value="Test" selected>Test</option>
<option value="Test2">Test2</option>
</select>
</form>

You could have just e-mailed me at struts@reumann.net and I would have
replied:) (As much as I'd like to, I don't always get a chance to check
all of these struts lists messages).
I think you must have caught this lesson during a brief transition
stage. A while ago I changed how I defined the tags in the jsp
pages. The current lesson reflects those changes. In the web.xml file
I'm declaring the tags as:
<taglib>
<taglib-uri>struts/html-el</taglib-uri>
<taglib-location>/WEB-INF/struts-html-el.tld</taglib-location>
</taglib>
and in the JSP you should then refer to the tag URI as:
<%@ taglib uri="struts/html-el" prefix="html" %>
I'm guessing your web.xml has the set up as above but your JSP is
following the old way I was calling the tags. Please let me know at
struts@reumann.net if this is NOT the case because I want to make sure
there are no errors in those labs.
Thanks,

I notice that a lot of people do that. Perhaps they are not used to threading
since Outlook has no clue what it is. Outlook is the only email client that
I have used that doesn't support it.
<disclaimer>
"Group by Conversation Topic" is NOT the same as threading!!

probably an obvious question, but are you sure you have a hidden form
field called "action" on this page so that your javascript function can
set it?

Re: newbie question - setting form parameter in Javascript
Posted by Firat TIRYAKI <fi...@pleksus.com.tr>.
probably you can not see the javascript error, because the form submits in
the function, remove the submit(); in the function and see the error, and
also I recommend you not to use onclick event, try onchange, it's better in
this situation.
