Question

我遇到了一个奇怪的问题。如果我使用任何两个<s:optiontransferselect>，下面的代码工作正常，但是当我添加第三个<s:optiontransferselect>时，导出到displayTag的excel功能不起作用。

JSP：

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@ taglib prefix="display" uri="http://displaytag.sf.net"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<script type="text/javascript">
function openPopUp(){
    document.getElementById('bankForm').setAttribute('target', '_blank');
    document.getElementById('bankForm').setAttribute('action', 'displayBankChartAction.action');
}
function noPopUp(){
    document.getElementById('bankForm').setAttribute('target', '');
}
</script>

            </tr> 
            </display:footer> 

    </display:table>

    </div>  
      <table>
      <tr>
        <td>
            <s:submit value="Show Chart" align="center" onclick="openPopUp();" />
        </td>
        <td>
            <s:submit value="Fetch Data" align="center" action="displayBankDataAction" onclick="noPopUp();" />
        </td>
      </tr>
     </table>

</s:form>
</body>
</html>

请有人请告诉我这里出了什么问题。

唯一的导出器知道显示表中有多少列。但它无法计算页脚中的列数。跨度值应等于有效HTML表的列数。

 <display:table class="bb" export="true" id="dTable" name="listBankBean" cellspacing="2px;" cellpadding="2px"  style="margin-left:10px;margin-top:20px;" requestURI="">
        <display:column property="dateTime" title="DateTime" headerClass="header1" style="border: 1px solid #B0B0B0;"/>
        <display:column property="channel" title="Channel" headerClass="header1" style="border: 1px solid #B0B0B0;"/>
        <display:column property="transactionType" title="Transaction Type" headerClass="header1" style="border: 1px solid #B0B0B0;"/>
        <display:column property="bic" title="Bic" headerClass="header1" style="border: 1px solid #B0B0B0;"/>
        <display:column property="volume" title="Volume" headerClass="header1" style="border: 1px solid #B0B0B0;"/>
        <display:footer media="all"> 
        <tr style="border: 1px solid #B0B0B0;">
            <td colspan="5">Total</td>
            <td><s:property value= "%{grandTotal}"/></td>
        </tr> 
        </display:footer> 

</display:table>
