struts2 s:if 判断两个变量是否相等

struts

 

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

 

 

以下是s:if来判断两个变量的值是否相等：

<select name="channelContent.channelTemplate">
  <option value="">--默认--</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="">--默认--</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>
