How to get the values entered in the field Filtered DataTable of Primefaces?

Question

I have a data table:

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

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

enter image description here

I know to get the value entered in a . This is possible through the get and set methods of backingBean. However I do not know to get the value entered in a field Filtered column: — Sant, Mar 18 '13 at 19:58
You should not do that in a getter/setter method. They should be kept untouched and not do anything else than just returning and setting a property. You should just access the `listaRegistros` in the action method. JSF has already set the values in there. — BalusC, Mar 18 '13 at 20:00

You can get the filter value from the datatable by

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"/>

And in your backing bean:

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

From the binding

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

How to get it from Javascript ? – rashidnk Aug 11 '15 at 10:57
@rashidnk Why would you need them in JavaScript? Can't you just simply query the DOM? – Jasper de Vries Mar 09 '17 at 12:02

Note: only bind to request scoped beans, never bind to view or session scope as it might cause duplicate IDs – Max Dec 10 '18 at 20:19

You can add a map to your bean, like:

private Map<String, Serializable> filterValues = new HashMap<>();

And bind the values to the map using the filterValue attribute of p:column, for example:

<p:column headerText="Name"
          sortBy="#{item.name}"
          filterBy="#{item.name}"
          filterMatchMode="contains"
          filterValue="#{yourBean.filterValues['name']}">
  <h:outputText value="#{item.name}" />
</p:column>

Advantage of this solution is that the values will be kept when you update your table.
