S2: concat doesn't work.
In one of my JSP page, I have javascript section
<code>
<script type="text/javascript">
var name = '<s:property value="additionalInterests[1].bankName"/>';
alert("Name: " + name);
</script></code>
It's working. I can see the valud of the Name.
But the below is not working if replace 1 with a variable
<code>
<script type="text/javascript">
var number = 1;
var name = '<s:property
value="additionalInterests['+number.toString()+'].bankName"/>';
alert("Name: " + name);
</script></code>
The result is empty.
Thanks for your helps!

Hi David,
Thank you for your explaination. I just started to work on Javascript
recently and have lots of things to learn.
Why is the first example working? It's a Struts2 tag insice the Javascript.
There are not much differences between the first example and the second
example except the second example replace 1 with a variable. But the
variable belongs to javascript. I guess i'm really confused.
appreciate your time,
panpan

You're getting confused about the role of Javascript in your
application, panpan. Javascript does not execute at the same time as
Java. Java can generate dynamic javascript on the server and send it to
a client. The javascript then executes on the client (web browser). You
cannot have javascript code evaluated inside your Java expressions as
per your example.

Thanks, Dave. That explains the problem I had for this example.

JavaScript is executed *AFTER* your JSP is compiled.
I'd recommend looking in to the way browsers/HTTP work
a bit.
