我可以使用media ='none'在displaytag中隐藏一列吗

Question

我可以使用来隐藏displaytag中的列media='none'吗？由于使用displaytag的另一列中的隐藏列中的值作为超链接的参数，是否还会因此而导致其他任何后果。

我成功隐藏了该列，但在服务器日志中得到了以下警告：

W org.displaytag.tags.ColumnTag setMedia属性“媒体”的无法识别的值value =“ none”

我尝试将课程用作隐藏课程，但没有进行锻炼，因此我继续使用媒体课程，但没有成功。

@ alfasin ...这是我的代码...我尝试将类用作隐藏类，但是它没有锻炼，所以我继续使用媒体，因为它没有作用，并且有效。

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

Answer 1

media='none'与相同media='abc'。

原因它找到“ABC”（或任何字符串）作为[玛雅]

您应该使用

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

并在您的CSS文件中。

.hidden {
 display: none;
}
