【问题描述】：

我正在使用显示标签。在我的显示：列中，我需要记录中的 href 链接，如果单击计数的链接，它会转到我的 struts 操作页面，同时我需要“哪个实例类型”和'rating element id'。所以请给我建议将值作为查询字符串传递..目前正在使用struts 1.2.9版我的示例代码是，

<c:if test="${(asnAccuracyListUID.instanceType != null && asnAccuracyListUID.instanceType != 'Sum')}">
    <display:column property="instanceTypeDescription" title="Instance Type" sortable="false"/>
</c:if>
<c:if test="${(asnAccuracyListUID.instanceType != null && asnAccuracyListUID.instanceType == 'Sum')}">
    <display:column property="instanceType" title="Instance Type" sortable="false" style="font-weight:bold;text-align:center"/>
</c:if>

<display:column property="firstWeekOfCount" title="${asnAccuracyFirstWeekOfCount}" sortable="false" >
    <a href="weeklyDlvyInstancesDashboardReportPost.do?method=WeeklyDlvyInstExcelReport&instanceType=${asnAccuracyListUID.instanceType}&ratingElementId=${asnAccuracyListUID.ratingElementId}">${asnAccuracyListUID.firstWeekOfCount}</a>  
</display:column>
<display:column property="secondWeekOfCount" title="${asnAccuracySecondWeekOfCount}" sortable="false"  />
<display:column property="thirdWeekOfCount" title="${asnAccuracyThirdWeekOfCount}" sortable="false"  />
<display:column property="fourthWeekOfCount" title="${asnAccuracyFourthWeekOfCount}" sortable="false" />
<display:column property="fifthWeekOfCount" title="${asnAccuracyFifthWeekOfCount}" sortable="false" />
<display:column property="sixthWeekOfCount" title="${asnAccuracySixthWeekOfCount}" sortable="false"/>

【问题讨论】：

您正在使用 Struts2... 尝试使用标签而不是 JSTL 标签，以及与和
啊好吧...顺便说一句，您的 URL 似乎不正确，您使用的是 '?' 的两倍标记参数...
@Swift 对不起，我打错了..
它在 href 属性中打印什么？
我输入了一些名称“详细信息”。但我想使用 property="firstWeekOfCount" 显示列值

标签： tags struts query-string displaytag querystringparameter

【解决方案1】：

从<display:column property="firstWeekOfCount" title="${asnAccuracyFirstWeekOfCount}" sortable="false" > 中删除property="firstWeekOfCount"

【讨论】：

如果我删除该属性，它不会显示任何内容。为什么你说要删除该属性。您是否出于特定原因想说什么？你能详细解释一下吗？谢谢。

我的问题是..
