Hi,
What I want to do is quite simple. I'd like to know how to test in a
<logic:iterate> when I'm at the first or last iteration.
My present problem is to parse a collection of String and display the
results like this :
### CODE : begin ###
value1, value2, value3
### CODE : end ###
And as you can see, for the last iteration, I mustn't displey the
comma character.
My present code is :
### CODE : begin ###
<logic:iterate id="e" name="myCollection">
<bean:write name="e" property="name" />,
</logic:iterate>
### CODE : end ###
Thanks in advance :)
Declare a counter variable in the loop. You can get the size of the
collection in a page variable with the <bean:size > tag and use that to
compare the current iteration. And then dont display the comma at the last
iteration.
This is trivial to do with JSTL; something like this should work:
<c:forEach items='myCollection' var='e' varStatus='status'>
<c:out value='e'>
<c:if test='${not status.last}'>
<c:out value=','/>
</c:if>
</c:forEach>
Strut 1's logic:iterate tag only provides a simple integer status
variable, which is why you have to jump through a few extra hoops using
that. Just one of the reasons JSTL is preferred over the logic:
collection :-)
