如何更改默认值p：dataTable emptyMessage消息

问题描述

我正在使用PrimeFaces的dataTable。我得到找不到记录。当表没有元素时。我想将此消息更改为无结果，并发出此消息i18n类型。

我不想使用

 < p：dataTable 
 id =idTable
 ... 
 emptyMessage =＃{messages ['general .message.EmptyList']}
> 
  

每个表。

我更改p：dataTable默认值 emptyMessage 消息？

解决方案

从PrimeFaces 3.5 DataTable 源代码：

  210 public java.lang.String getEmptyMessage （）{
 211 return（java.lang.String）getStateHelper（）。eval（PropertyKeys.emptyMessage，No records found。）; 
 212} 
  

所以，它是硬编码，没有办法在一个单一的除了攻击PrimeFaces源或创建一个 < p：dataTable> 具有所需的消息集。

 < ui：composition ...> 
< p：dataTable id =＃{id}value =＃{value}var =item
 emptyMessage =＃{messages ['general.message.EmptyList']} > 
< ui：insert /> 
< / p：dataTable> 
< / ui：composition> 
  

  dataTable id =foovalue =＃{bean.items}> 
< p：column>＃{item.foo}< / p：column> 
< p：column>＃{item.bar}< / p：column> 
< / my：dataTable> 
  

如果您实际上不想更改消息，而只是想要隐藏它，那么您也可以选择一个纯CSS解决方案：

  .ui-datatable-empty-message {
 display：none; 
} 
  

I am using PrimeFaces' dataTable. I get "No records found." when table has no element. I want to change this message to something like "No result" and make this message i18n type.

I don't want to use

<p:dataTable
    id="idTable"
    ...
    emptyMessage="#{messages['general.message.EmptyList']}"
>

for every table.

How can I change p:dataTable default emptyMessage message?

解决方案

From the PrimeFaces 3.5 DataTable source code:

210    public java.lang.String getEmptyMessage() {
211        return (java.lang.String) getStateHelper().eval(PropertyKeys.emptyMessage, "No records found.");
212    }

So, it's hard coded and there's no way to change it in a single place other way than hacking the PrimeFaces source or creating a tagfile (not composite!) <my:dataTable> which wraps the <p:dataTable> with the desired message set.

<ui:composition ...>
    <p:dataTable id="#{id}" value="#{value}" var="item"
        emptyMessage="#{messages['general.message.EmptyList']}">
        <ui:insert />
    </p:dataTable>
</ui:composition>

<my:dataTable id="foo" value="#{bean.items}">
    <p:column>#{item.foo}</p:column>
    <p:column>#{item.bar}</p:column>
</my:dataTable>

If you actually don't want to change the message, but merely want to hide it altogether, then you could also opt for a pure CSS solution:

.ui-datatable-empty-message {
    display: none;
}
