如何获取在Primefaces的Filtered DataTable字段中输入的值？

Question

我有一个数据表:

<p:dataTable id="pDataTableListaRegistros"
             var="registro"
             value="#{arquivoBean.listaRegistros}"
             paginator="true"
             rows="20"
             filteredValue="#{arquivoBean.filteredListaRegistros}"
             styleClass="tabelaCentralizada">

我想获得在过滤字段"Code","Data do Registro"和"Usuário"中输入的值来操作支持bean.

Answer 1

您可以从数据表中获取过滤器值

1. 通过绑定或遍历树,从视图中获取对数据表的引用.通过绑定,您将拥有:

      <p:dataTable binding="#{arquivoBean.theDataTable}" id="pDataTableListaRegistros" var="registro" value="#{arquivoBean.listaRegistros}" paginator="true" rows="20" filteredValue="#{arquivoBean.filteredListaRegistros}" styleClass="tabelaCentralizada"/>
   

   在你的支持bean:

      DataTable theDataTable = new DataTable();
      //getter and setter
   

2. 从绑定

      Map<String, String> theFilterValues = theDataTable.getFilters(); //This returns a map of column-filterText mapping.
