如何获取在Primefaces的Filtered DataTable字段中输入的值? [英] How to get the values entered in the field Filtered DataTable of Primefaces?

问题描述

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">

我想获取在过滤器字段"Code"，"Data do Registro"和Usuário"中输入的值，以便在支持bean中进行操作.

I would like to get the values ​​entered in filter fields "Code", "Data do Registro" and "Usuário" to manipulate in a backing bean.

推荐答案

您可以通过以下方式从数据表中获取过滤器值:

You can get the filter value from the datatable by

1. 通过绑定或遍历树从视图获取对数据表的引用.通过绑定，您将拥有:

1. Obtain a reference to the datatable from the view either by binding or walking the tree. By binding, you'll have:

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

在您的支持bean中:

And in your backing bean:

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

来自绑定

From the binding

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