jsp - 我可以使用媒体 ='none' 在 displaytag 中隐藏一列吗

Question

我可以使用 media='none' 在 displaytag 中隐藏一列吗？ ?是否会因此产生任何其他后果，因为我使用 displaytag 另一列中隐藏列的值作为超链接的参数。

我成功隐藏了该列，但得到了以下信息:服务器日志中的警告

W org.displaytag.tags.ColumnTag setMedia Unrecognized value for attribute "media" value="none"

我尝试使用类作为隐藏，但它没有锻炼，所以我继续使用媒体，因为没有并且它起作用了。

   <table border="1"  width="100%"   align="center" cellpadding="0" cellspacing="1"    class="table_main">


<display:table name="requestScope.ITIReportForm.rprtData" id="table" export="true" sort="list" requestURI="/itireport.do"   pagesize="20" align="center"  class="table_main" width="100%">

<display:column width="5%"  align="center" media="html" titleKey="" headerClass="table_header" title="Request No">

Answer 1

media='none'与 media='abc' 相同.

Reason it finds 'abc' (or any string) as [mymedia]

你应该使用

<display:column property="index" title="" class="hidden" headerClass="hidden" /> 

而在您的 CSS文件。

.hidden {
 display: none;
}
