Hi everybody,
One of my programmer asked me the following:
I try to set the current value of a s:iterator in the "onclick" of a "s:a"
tag, but it doesn't work. How can I do this?
I know that I can't use something like overlapping tags:
<s:iterator value="nbPages">
<s:a href="#" onclick="javascript:refresh(<s:property />);return
false;"><s:property /></s:a>
</s:iterator>
Here, I put <s:property /> inside onclick attribute, the output is:
# 1
(not very surprising...)
Since I resolved his problem while starting to write this question in the
Struts forum, I'll nevertheless send the solution, in the case other new
users of Struts 2 have the question.
The solution is to use use OGNL (or EL, expression language, if your JEE
version is 4 or 5):
<s:iterator value="nbPages">
<s:a href="#" onclick="javascript:refresh(%{top});return
false;"><s:property /></s:a>
</s:iterator>
"top" represent the current element of the iterator. It is a keyword in
OGNL/Struts 2 (correct me if I'm wrong).
Cheers,
Cyril Gambis
