struts2 循環判斷字符串方法及s:if判斷兩個變量值相等

<s:if test="#request.defaultItemList!=null"> <s:iterator value="#request.defaultItemList" var="str"> <s:if test="#str=='contentImg'"> 呵呵終於找到你啦 </s:if> </s:iterator> </s:if>

 

以下是s:if來判斷兩個變量的值是否相等：

<select name="channelContent.channelTemplate">
  <option value="">--默認--</option>
  <s:if test="#request.channelTemplateList!=null">
   <s:iterator value="#request.channelTemplateList" id="template">
    <option value="<s:property />" <s:if test="#template==channelContent.ChannelTemplate"> selected="selected" </s:if> >
     <s:property />
    </option>
   </s:iterator>
  </s:if>
</select>
 

<select name="channelContent.channelTemplate">
  <option value="">--默認--</option>
  <s:if test="#request.channelTemplateList!=null">
   <s:iterator value="#request.channelTemplateList" var="template">
    <option value="<s:property />" <s:if test="%{#template==channelContent.ChannelTemplate}"> selected="selected" </s:if> >
     <s:property />
    </option>
   </s:iterator>
  </s:if>
</select>
