jstl loop displaying 3 items from a list

  • 772

I am trying to iterate through a list of 8 specific items. I would need to show the first three, but it has not been very clear to me how to do it.

I appreciate the help.

<c:forEach begin="0" step="1" end="3" items="${Articulos}">
                <div>${item.idArticulo}</div>
                <a class="destacado my-2" style="word-break: break-word;" 
                  href="${item.url}">${item.nombre}</a> 
</c:forEach>

I know it's not right but at least it serves to explain my doubt.

In the list of articles, I have 8 articles, I want it to show me only 3 articles.

    You're using itemas a variable to refer to the item in each iteration, but you haven't declared it, I think that's the only thing you're missing:

    <c:forEach begin="0" step="1" end="2" items="${Articulos}" var="item">
    <div>${item.idArticulo}</div>
    <a class="destacado my-2" style="word-break: break-word;" 
                  href="${item.url}">${item.nombre}</a> 
</c:forEach>

    A detail: the index starts at 0 and endindicates the limit inclusively, so to show the first three elements you need to set it to 2, not 3
