JSTL 实现 为Select赋多个值

需要注意需要在.jsp文件中引入相应的类库

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>

<select id="rights" name="rights" multiple="multiple">
   <c:forEach items="${tqListAll}" var="tq">
      <c:set var="isContains" value="${fn:contains(tqListSelected,tq.id)}" />
      <c:choose>
         <c:when test="${isContains}">
            <option value=${tq.id} selected="selected">${tq.name}</option>
         </c:when>
         <c:otherwise>
            <option value=${tq.id}>${tq.name}</option>
         </c:otherwise>
      </c:choose>
   </c:forEach>
</select>
