odd/even element in list model

[Giulio Fior]

Hi all,

I'm trying to create a list model in which odd elements has a different html code

odd element

<li><img src="$content.icon.getImagePath("0")">

even element

<img src="$content.icon.getImagePath("0")"></li>

is this possible?

I dont' think it's possible using only Velocity :-/

You could try with custom Java code, but that is beyond my ability to help someone (I'm not a Java programmer)

or you can use VTL, since in the loop velocityCount is the current index:
# if($velocityCount % 2 == 0) .. is an even line

Hi,

you can try doing something like this using the modulo operation with $velocityCount

<ul>
#foreach( $product in $allProducts )
   $set ($even = $velocityCount % 2)
   <li> even: $even | $product</li>
#end
</ul>

In a list model there's no #foreach loop, $velocityCount  is always = 1.

I think I need some java code.

Giulio if you are using the "content list" widget so you have to think different at the problem :)

We know the list is generated from the jsp content_viewer_list.jsp 

so there's a <c:forEach> there. Maybe you can customize it.

Another way could be the use CSS3 with the :nth-child selector.

However this is not supported by some old browsers.

Let us know how you'll handle that ;)
