passing multiple variables in JET2 control tag <c:iterate> [message #51838] Fri, 22 September 2006 06:20 Go to next message

How to pass multiple variables in a JET control tag for instance Iterate.

<c:iterate select="value" var="p">

content of iterate

</c:iterate>

If I want to have another variable called q in the var= "p,q" .. How to
declare this another variable. Is it possible in the first instance??

Any help regarding this will be appreciated.

Thanks
Lakshmi

Lakshmi:

The variable created by <c:iterate> refers to the current instance of the
collection of objects identified by evaluating the 'select' expression. It
makes no sense to me to define multiple variables refering to that object.
The body of the <c:iterate> can reference other variables than just the one
created in the tag - it may access any currently defined variable.

An example: If you hand a model like this:

<company name="ABC Inc">
<person name="Jim">
<skill technology="Java"/>
<skill technology="JET"/>
</person>
<person name="Bob">
<skill technology="Cobol"/>
<skill technology="JET"/>
</person>
</company>

A very typical way to traverse this would be:

<c:setVariable select="/company" var="$company"/>

<c:iterate select="$company/person" var="person">
<%-- here you can access $companyand $person --%>
<c:iterate select="$person/skill" var="skill">
<%-- here you can access $company, $person and $skill --%>
Person <c:get select="$person/@name"/> with skill <c:get
select="$skill/@technology"/> works at <c:get select="$company/@name"/>.
</c:iterate>
</c:iterate>

Let me know if I've misunderstood your question.
