then why were you trying to reference the rendered content like this?
document.forms[0].targetDate[tmpIndex]
for a form element like this
<input name="eventList[0].targetDate" />
i'm not assuming you're hard coding this ...
i gave you a hard coded example to identify the problem, i'm a little concerned you didn't twig. . and beginning to see how the divergent coding styles came to coexist.
the targetDates aren't indexed or are they?
onclick="alert('document.forms[0].elements['eventList[<%= tmpIndex %>].targetDate'].value')"
or
onclick="alert('document.forms[0].elements['eventList[<bean:write name="tempIndex" />.targetDate'].value')"
NOT your, is that special JSP then?
onclick="alert(document.forms[0].targetDate[tmpIndex].value')"
tmpIndex will not be preprocessed by the server using your "methodology" in addition to this you're javascript isn't doing anything. According to this little gem you trying to (ignoring the js issue) reference a javascript variable called tmpIndex. However the fact that you defined tmpIndex using the bean:define suggests that this wasn't a js variable but a java/jsp one.
alert boxes are the traditional means of debugging javascript, i drew you straight to the problem an' the best you came up with was that page line and trying to teach me arraylists are good for punching out html tables.. I think i should be the one thanking you for such a perl of wisdom :o)

Mark,
Thanks.... that wasn't a long wait!
Anyway....I think you're assuming I'm hardcoding this...I think.
I am using the nested tags from Struts and, specifically, the
nested:iterate tag. I'm not sure if I'm being presumptuous, but are you
taking this into account? The tmpIndex is the actual iteration index that
the tag uses to generate values from the ArrayList...usually good for
building things in tables.
The trick I'm trying to solve is putting together this statement in a form
javascript will accept it inside the nested:iterate tag.
This value is generated by the tag and can be obtained from the tmpIndex.
I V document.forms[0].elements['eventList[0].targetDate' document.forms[0].elements['eventList[1].targetDate' document.forms[0].elements['eventList[2].targetDate' .....
Thanks very much for the help. I hope we're on the same page.

Sorry it took me a while to get back to you..
I reduce things down to this.. whats this mystrious tempIndex ? does this help.. i strip out the calender thingy. You need to know how to drill to form elements that are generated as indexed properties, in javascript. Any way does this help?
<form name="marksForm">
<input type="text" name="eventList[0].targetDate" value="Mellow
world!!">
<input type="text" name="eventList[1].targetDate" value="Mellow world
2!!">
</form>
<a href="javascript:void(0)"
onclick="alert(document.forms[0].elements['eventList[0].targetDate'].va l
ue)">hit me!!</a>
<a href="javascript:void(0)"
onclick="alert(document.forms[0].elements['eventList[1].targetDate'].va l
ue)">hit me 2!!</a>

Mark (et al), Here is the rendered html output from the jsp. I don't think there are any inconsistencies, but please give me more detail if you see something. This works fine when it's not in a nested:iterate loop. I just need to get a document object reference that includes the resolved index and be able to pass it to the javascript function.
I have to believe someone out there has done something similar and is as little expert in mixing javascript and struts as I am.
Thanks for the quick response, Joe

Could be more javascript than tag-libs..
You've a few inconsistancies in approach at first glance.. targetDate
looks like it should be a variable not a string literal.. Can you paste
the code that arrives to the web browser (i.e. without the struts
tags)?

I'm trying to use Matt Kruse's javascript calendar popup (http://www.mattkruse.com/javascript/calendarpopup/) inside a nested:iterate. This is likely a javascript question, but I would appreciate any help.... and it may help others save looking through the archives for the 8+ hours I've spent already trying to find this.
The call to "cal1" on the "onselect" fails. I've tried every
permutation I
could think of. I've tried putting the document element reference in a
variable and calling it that way, but it seems the tmpIndex will not
resolve. This would seem to be a generalized problem for referencing
any
form property in a javascript function call involving nested:iterate
elements. Once again, please, any help vastly appreciated.
Here is the jsp excerpt:
<<<<<
<nested:iterate property="eventList" id="ev" indexId="evIdx">
<table width="924" border="4" cellpadding="0" cellspacing="0">
<bean:define id="tmpIndex" value="<%=
String.valueOf(evIdx.intValue())%>"/>
