Question

Using struts2 with jsp with standard struts tag libraries.

I’m trying to dynamically hide a DIV on page load, but still send it to the browser. This is so I can show it later via javascript.

The request objects one and two are not easily referenced via a jsp:usebean tag. (They are enums and cannot be instantiated) I tried using a combination of s:if tags or c:if tags and it just looks ugly.

<%
    String displayStr = "display: none;";
    if(request.getAttribute("one") != null || request.getAttribute("two") != null  ) {
        displayStr = "display: block;";
    }
 %>

<div id="next" style="<%=displayStr %>">

Any suggestions for a better way to do this?

Using JSTL:

   <c:set var="displayStr" value="display:none"/>
   <c:if test="${!empty one || !empty two}">
        <c:set var="displayStr" value="display:block"/>
   </c:if>
   <div id="next" style="${displayStr}">
