Primefaces:在datatable上设置页面

Question

我在primefaces中有一个数据表,我想,当我在其中添加一行时,查看数据表的最后一页.

我的.xhtml页面是:

<h:form id=...>
...
<p:dataTable var="webTemplate" id="templateTable" widgetVar="tbl1"/>
...
</h:form>

<h:form id=...>
...
<p:inputText id="txt_description" value="#{templateController.templateDescription}" label="templateDescription">
               <f:validateLength for="txt_name" minimum="1"/>
               <p:ajax event="change"
                     listener="#{calculatePageTable.setPageTableTemplate}"  onsuccess="setTabIndexTT()"/>
               </p:inputText>
...
</h:form>
<script type="text/javascript">
      function setTabIndexTT(){
                    tbl1.getPaginator().setPage(#{calculatePageTable.pageTableTemplate});
                }
      </script>

豆:

@ManagedBean
@SessionScoped
public class CalculatePageTable {

   private int pageTableTemplate = 0;
   private int pageTableField = 0;

   public void setPageTableTemplate() {

      final DataTable d = (DataTable) FacesContext.getCurrentInstance().getViewRoot()
            .findComponent("form:templateTable");
      pageTableTemplate = d.getPageCount() - 1;

   }

   public int getPageTableTemplate() {
      return pageTableTemplate;
   }

   public void setPageTemplateField() {

      final DataTable d = (DataTable) FacesContext.getCurrentInstance().getViewRoot()
            .findComponent("detailsTable:webTemplateUpdateTable");
      pageTableField = (d.getPageCount() - 1);
   }

   public int getPageTableField() {
      return pageTableField;
   }

}

但是onsccess ajax永远不会调用js函数setTabIndexTT()...

添加行时如何设置数据表的最后一页？

Primefaces版本是3.1.1

在您的托管bean中,您可以尝试以下代码:

public void setPageDataTable() {
    final DataTable d = (DataTable) FacesContext.getCurrentInstance().getViewRoot()
        .findComponent("form:templateTable");
    int first = 1;
    if (d.getRowCount() % ROWS_DATATABLE == 0) {
        first = (d.getRowCount() - ROWS_DATATABLE);
    }
    else 
    {
        first = (d.getRowCount()/ROWS_DATATABLE)*ROWS_DATATABLE;
    }
    d.setFirst(first);
}

添加新行时调用此方法

如果datatable widgetVar是dataTableWidget,那么使用:

<script type="text/javascript">
            $(document).ready(function () {
                dataTableWidget.paginator.setPage(0);
            });
 </script>
