- Java code
<select id="goodsTypeId" > <s:iterator id="gType" value="#request.listGoodsTypeData" status="index"> <option id="${index}" <c:if test="${gdType.id == 3} "> selected="true" </c:if> >${gType.name }</option> </s:iterator> </select>这里面的C:IF完全无效.请问是什么原因
原本的判断应该是这样的
<c:if test="${gdType.id == goodsData.goodsTypeId}">
两个ID值是必然有相当的.但是却没有效果.如果单独拿出来不在<s:iterator >中就行
