Question

I’m looping through a list of items, and I’d like to get a request parameter based on the item’s index. I could easily do it with a scriptlet as done below, but I’d like to use expression language.

<c:forEach var='item' items='${list}' varStatus='count'>     <!-- This would work -->    <%=request.getParameter('item_' + count.index)%>     <!-- I'd like to make this work -->    ${param.?????}  </c:forEach> 

Answer 1

<c:set var='index' value='item_${count.index}' /> ${param[index]} 

Unfortunately, + doesn’t work for strings like in plain Java, so

${param['index_' + count.index]} 

doesn’t work ;-(
