The question is published on by Tutorial Guruji team.
its me again. Basically Im checking the roles of a user once they hit a page. Its an array, lets say 1,2,3. The contents of the last column on the jsp for testing has the role #’s that are attached to each individual attachment. The last column wont be on the finished product, but I need to do some sort of IF on that array to see if any of the values in the array:
<c:forEach items = "${hotPartRoles}" var = "hpRole">
${hpRole.id}
</c:forEach>
are in the array of the attachment roles:
<c:forEach items = "${item.roles}" var = "role">
${role.id}
</c:forEach>
jsp:
<table class="data_table">
<tr>
<th>Attachments</th>
//These are the user's Roles
<c:forEach items = "${hotPartRoles}" var = "hpRole">
${hpRole.id}
</c:forEach>
</tr>
<tr>
<td class="subtable">
<table class="data_table">
<c:choose>
<c:when test='${empty attachList}'>
<tr>
<td>No Attachments</td>
</tr>
</c:when>
<c:otherwise>
<tr>
<th>Remove Attachment</th>
<th>File Name</th>
<th>File Type</th>
<th>File Size (bytes)</th>
<th>File Attached By</th>
<th>Date/Time File Attached</th>
<th>Roles</th>
</tr>
<c:forEach var="item" items="${attachList}" varStatus="loopCount">
<tr>
<td class="button">
<rbac:check operation="<%=Operation.DELETE%>">
<button type="button" onclick="javascript:delete_prompt(${item.id});">Delete</button>
</rbac:check>
</td>
<td><a href="show.view_hotpart_attachment?id=${item.id}">${item.fileName}</a></td>
<td>${item.fileType}</td>
<td><fmt:formatNumber value="${item.fileSize}" /></td>
<td>${item.auditable.createdBy.lastName}, ${item.auditable.createdBy.firstName}</td>
<td><fmt:formatDate value="${item.auditable.createdDate}" pattern="${date_time_pattern}" /></td>
<td>
<c:forEach items = "${item.roles}" var = "role">
${role.id}
</c:forEach>
</td>
</tr>
</c:forEach>
</c:otherwise>
</c:choose>
</table>
Now the arrays ont need to match exactly, just a value in the array of user roles is in the array of attachment roles….
I need to do the check here to determin whether or not to put a disable flag on the “delete” button:
<rbac:check operation="<%=Operation.DELETE%>">
<button type="button" onclick="javascript:delete_prompt(${item.id});">Delete</button>
</rbac:check>
</td>
<td>
Answer
Doing 2 nested for loops and having a var set to false initially, then set to true and checking on that var seemed to work
<c:forEach var="item" items="${attachList}" varStatus="loopCount">
<c:set var="dispVal" value="false"/>
<c:forEach items = "${item.roles}" var = "role">
<c:forEach items = "${hotPartRoles}" var = "hpRole">
<c:if test="${hpRole.id == role.id}">
<c:set var="dispVal" value="true"/>
</c:if>
</c:forEach>
</c:forEach>
<tr>
<td class="button">
<rbac:check operation="<%=Operation.DELETE%>">
<button type="button"<c:if test="${dispVal != 'true'}"> disabled="disabled"</c:if>
onclick="javascript:delete_prompt(${item.id});">Delete</button>
