JSP Code:
<c:forEach items="${alerts.npUserList}" var="alertsUser">
<c:if test="${not empty fn:trim(alertsUser.email)}">
<p>
<input type="checkbox" id="pageTrack_<c:out value='${alertsUser.id}' />" class='pageTrack' name="pageTrack" value="<c:out value='${alertsUser.id}' />" />
<c:out value="${alertsUser.email}" />
</p>
</c:if>
</c:forEach>
Jquery Code:
var pageTrack = (jq("input[type='checkbox'][name='pageTrack']:checked").length > 0);
The above jquery code will return true when one or more than one check box selected.
