forEach var

[John Ip]

Hi guys,

I would like to ask is there any way to reference the var of a forEach tag within a scriptlet? I would like to do some maunipulation to the var in a scriptlet.

<c:forEach var="item" items="items">

<% item.decrypt() %>

</c:forEach>

The whole point of JSTL is that you DON'T use scriptlet code ;-)

JSTL variables are stored in the page, request, session and application scopes.

In java scriptlet code you can get at it like this:

 
<%
Item item = (Item)pageContext.getAttribute("item");
item.decrypt();
%>
 
// or alternatively use the useBean tag to declare a scriptlet variable.
<jsp:useBean id="item" class="com.mypackage.Item" scope="page"/>
<% item.decrypt %>

Cheers,

Thanks for that mate!
I did try my best to prevent using scriptlet.... but simple things like if else statement..... is so lengthy to write in the current jstl 2.0 ......
<choose>
<when>
</when>
<when>
</when>
<otherwise>
</otherwise>
</choose>

but with scriptlet

<% if () { %>
<% } else { %>
<% } %>

nice and clean isn't it? Hope the next version of jstl will improve on this.

Well, its lengthy but dont you think its more clear and readable than a scriplet for everyone, a java programmer and a html author? One more positive thing about this is, you dont have to mess up with code and tags. When its about authoring a web page, tag like structure is highly encouraged.

Despite, all these kind of thoughts, isn't it better to follow the conventions and best practices?

It might be more terse but I wouldn't call it clean.

I think it would be particularly unclean to have a combination of JSTL and scriptlets in the same page.
