Question

我使用jsf并有一个启用过滤的primefaces数据表。

<p:dataTable value="#{tcsInstanceBean.tcsJList}" var="return" scrollable="true" scrollHeight="550" 
                    widgetVar="returnTable"
                    emptyMessage="Nothing found matching given criteria"
                    filteredValue="#{tcsInstanceBean.filteredTcsJList}"
                    styleClass="returnTable, selectable"
                    headerClass="returnTableHeader"
                    rowClasses="returnTableOddRow,returnTableEvenRow"
                    resizableColumns="true">

                    <p:column class="returnColumn" style="width:40%;"
                        sortBy="#{return.path}"
                        filterBy="#{return.path.fileName}"
                        filterMatchMode="contains">
                        <f:facet name="header">Job Path</f:facet>
                        <a href="file:///#{return.path}" target="_blank">#{return.path.fileName}</a>
                    </p:column>


</p:dataTable>

我希望在过滤后输出所有可见的总行数。目前我只计算清单并输出它。

jobsCounter = "We found " + tcsJList.size() + " Jobs!";

如何在过滤后计算所有可见行？

Answer 1

编写类似

的方法

public int count(){
  if(getTcsInstanceBean().filteredTcsJList!=null){
    return getTcsInstanceBean().filteredTcsJList.size();
  }
  else {
    return getcsInstanceBean().tcsJList.size();
  }
}

或使用currentPageReportTemplate

<p:dataTable value="#{tcsInstanceBean.tcsJList}" var="return" scrollable="true" scrollHeight="550" 
                widgetVar="returnTable"
                emptyMessage="Nothing found matching given criteria"
                filteredValue="#{tcsInstanceBean.filteredTcsJList}"
                styleClass="returnTable, selectable"
                headerClass="returnTableHeader"
                rowClasses="returnTableOddRow,returnTableEvenRow"
                resizableColumns="true"
                paginator="true"
        paginatorTemplate="{CurrentPageReport}"
        currentPageReportTemplate="We found {totalRecords}, Jobs!">

                <p:column class="returnColumn" style="width:40%;"
                    sortBy="#{return.path}"
                    filterBy="#{return.path.fileName}"
                    filterMatchMode="contains">
                    <f:facet name="header">Job Path</f:facet>
                    <a href="file:///#{return.path}" target="_blank">#{return.path.fileName}</a>
                </p:column>
</p:dataTable>
