Re: [S2] Newbie Passing S2 variables to javascript functions
Without seeing the error and the JSP code that generated it, it's hard
to tell you what's wrong. However, remember that Javascript runs on the
client, after the page has been generated. View the page source to see
what the syntax error is. In this case, it's probably the lack of quotes
around the OGNL expression. It may also be that an in-line expression
like that wont work.
Here's a couple of suggestions to try:
... onclick=enableField('%{#indexValue}') ...
... onclick=%{'enableField(\'' + #indexValue + '\')'} ...
... onclick=enableField('${indexValue}') ...
I've tried all your suggested variations, but looking at the source,
all the expressions are passed as a string, there's no evaluation of
the expression. Which, now you've explained that Javascript executes
on the client makes sense. So the question becomes is it possible to
interact with the action stack in Javascript?

just make sure the indexValue is available when you use it.

Re: [S2] Newbie Passing S2 variables to javascript functions
Again, though, bear in mind that the s:proprty/ tag will be evaluated
on the server during page generation whereas the Javascript will be
executed later, on the client, after the page is delivered.
There's no way to 'interact with the action stack in Javascript', since
the action stack only exists during page generation and the Javascript
runs later.
That said, techniques like the one Musachy shows below, or the previous
examples, *will* allow you to push data from the action stack into your
scripts at page generation time. You just can't dynamically reference
the action stack 'live' from Javascript.

I'm not sure what you mean here; the only thing you can 'pass' is a
Javascript literal, but that could be a string, integer, even an object
literal. Just remember that you're generating code, so whatever you
generate has to be syntactically valid when the browser comes to run it.
If this is all still unclear, maybe you can describe what you are trying
to achieve in a little more detail.

[S2] Newbie Passing S2 variables to javascript functions
Hi
Within a s:iterator tag I have the following statement s:set
name=indexValue value=#status.index/ (because status seems to
disappear when the iterator exits) and I use the expression
%{#indexValue} within other struts s: tags without a problem.
I now need to pass this value to a javascript function i.e
onclick=enableField(%{#indexValue}) but the browser complains about
invalid syntax. How do I pass the value indexValue to a javascript
function?
Regards
Roger

Re: [S2] Newbie Passing S2 variables to javascript functions
Once you've setted this var, you can use Plain Old EL to get it.
${indexValue} should work .
A good pratice in this case is define the scope you're setting this var.

Felipe
