Subject: RE: how to pass a jsp variable to a javascript function
Howdy,
There are definitely a number of funky things in your code example. I'm
not
exactly sure what you're trying to do since your onchange attribute is
calling a JavaScript function called "projectChange" which I don't see
anywhere, but here are a couple of things to look out for:
1. I don't believe you can use a JSP expression inside some JavaScript
code, but someone can certainly correct me if I'm wrong. What I have done
in the past is use a <bean:write> tag, so you should be able to do
something
like:
<bean:define id="tmpIndex" value="23"/>
<script language="JavaScript" type="text/javascript">
var y<bean:write name="tmpIndex"/> = <bean:write name="tmpIndex"/>;
</script>
if you *really* want to do that.
2. However, your question was "how do I pass a JSP variable to a
Javascript
function" and it looks like this is what you are attempting to do with the
next part of your code:
<nested:select property="projectCodeId"
onchange="projectChange(y<%=tmpIndex%>)">
For this to work correctly, your JSP expression needs to be the entire
value
for the onchange attribute (i.e., you can't embed a JSP expression into
the
middle of an attribute value). Thus, assuming you have a JavaScript
function named "projectChange" defined, and you really want to pass in a
JavaScript variable to this function as opposed to say, the Integer value
itself, then you should be able to say something like:
<nested:select property="projectCodeId" onchange='<%= "projectChange(y" +
tmpIndex +")" %>'>
3. But, rather than setting a JavaScript variable inside a nested:iterate
and then trying to pass this variable into "projectChange" it would seem
to
be much simpler to simply pass in the value itself. In other words,
something like:
<nested:iterate property="projectList" id="pro" indexId="proIdx">
<nested:select property="projectCodeId" onchange='<%= "projectChange(" +
proIdx +")" %>'>
I haven't tested the above, but if I haven't missed any syntactic sugar,
it
should work.
Cheers,
-Steve

I don't have javascript errors, the problem is <%=tmpIndex%> can't be
translated into 0,1,2,.....
in javascript, only the String"<%=tmpIndex%>".

Hi Julie,
what do you get as a result of that iterate? It looks correct. Do you
have javascript errors?
