Ajax
Hi,
In the following code the children(${id}) function is called when you click
on the children button. Now ajax works ok and I get the correct results
back(I'm using prototype.js). My problem is that I want to use the <s:iterator
tag in order to iterate through the returned values. Is this possible or I
can't do it because <s:iterate is used to render the page and its not
available on the ajax call?
<table>
> <tr>
> <th>Id</th>
> <th>First Name</th>
> <th>Last Name</th>
> </tr>
> <s:iterator value="persons">
> <tr id="${id}">
> <td><s:property value="id"/></td>
> <td><s:property value="firstName"/></td>
> <td><s:property value="lastName"/></td>
> <td><input type="button" onclick="children(${id})"
> value="children"/></td>
> </tr>
> <s:iterator id="result" value="children">
> <tr>
> <td><s:property value="id"/></td>
> <td><s:property value="firstName"/></td>
> <td><s:property value="lastName"/></td>
> </tr>
> </s:iterator>
> </s:iterator>
> </table>
Thanks

Re: Ajax

yes but I can call an action that has as a result another jsp page, so I can
use the iterator in that page and then fetch back the results and input them
in the initial page(where the ajax call has been done from). At least thats
what I'm trying now and it works, not exactly as I want yet but it seems it
will.
does this make sense or am I talking nonsense?

Re: Ajax

I thought so too. In any case, you can use any Struts 2 on you JSP pages,
even if it is an ajax call, it doesn't matter to Struts. If what you are
trying to use is the iterator tag on you javascript code, then no, the tags
get executed when your page is rendered, on the *server*, while the response
can be processes on the *client*.

Oh. Hrm.
I guess I'm not sure what the problem is then; maybe
you could describe all the steps. I had assumed that
you were calling an S2 action and using the results of
the rendered JSP to set innerHTML or something
similar.

Can you elaborate a bit more on this? The ajax call is calling a struts
action already so I'm not sure I understand you...
thanks

If you are getting back text or JavaScript values from
a Prototype Ajax call then <s:iterator.../> won't
work: JSP tags execute on the server side, not the
client side.
You could make your Ajax call to a Struts Action and
return the results of *that* if you wanted.
