我可以使用media ='none'來隱藏displaytag中的列嗎？

Question

可以使用media='none'隱藏displaytag中的列嗎？在使用displaytag的另一列中的隱藏列的值作爲超鏈接的參數時，是否會產生其他任何後果。

我成功地隱藏列，但得到FOLL：在服務器日誌警告

W¯¯org.displaytag.tags.ColumnTag setMedia無法識別的價值屬性的「媒體」價值=「無​​」

我嘗試使用類作爲隱藏，但它沒有鍛鍊，所以我繼續與媒體作爲沒有和它的工作。

Answer 1

media='none'與media='abc'相同。

原因找到 'ABC'（或任何字符串）爲[瑪雅]

你應該使用

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

而在你CSS文件。

.hidden { 
display: none; 
}
