PrimeFaces，无法更新选项卡禁用属性

Question

当用户使用 rowEditor 编辑数据表时，我需要更新选项卡的禁用属性。
我在监听 event="rowEdit" 的 dataTable 中有一个 ajax 标记，它调用将选项卡的 disabled 属性设置为 true 的支持 bean 方法。
如果我仅引用带有 tabView id 的选项卡组，如update=”:tabView” 中的那样，该选项卡将更新，但只有已编辑的 dataTable 行呈现没有网格线。如果我在update=”:tabView:tab” ID 中引用选项卡，则 dataTable 可以正常呈现，但选项卡的 disabled 属性不会。
正在更新的选项卡与正在编辑的数据表不在同一个选项卡中。
数据表位于rates 选项卡中，我要更新的选项卡是tbVSelRates

PrimeFaces 3.4.2、JBoss 6.0.1 JSF 2.0 希望这个帖子正确，第一次在 StackOverflow 上发布问题 谢谢

  public void applyRowChangesMassUpdate(RowEditEvent event){
    DataTable dtRates = (DataTable) event.getSource();
    Product dtRow = (Product)dtRates.getRowData();
    logger.log(Level.FINE, "Molecule: {0}", dtRow.getMolecule());
    logger.log(Level.FINE, "Projected Sales: {0}", dtRow.getYtdProjectedSales());
    logger.log(Level.FINE, "Planned Rate: {0}", dtRow.getPlannedRate());
    if(dtRow.getPlannedRate()!= null && dtRow.getYtdProjectedSales() != null){
    dtRow.setPlannedPAProjected(new BigDecimal(0.01 *         dtRow.getYtdProjectedSales().doubleValue() * dtRow.getPlannedRate().doubleValue()));
    }
    logger.log(Level.FINE, "Planned PA Projected: {0}", dtRow.getPlannedPAProjected());
    conRatesTabDisabled = true;
    tabIndex = 1;
}

Answer 1

计划是通过p:remoteCommand 调用applyRowChangesMassUpdate 并禁用标签 使用 PrimeFaces Javascript API。可以这样做：

为您的p:dataTable 赋予widgetVar 属性，例如dataTableWV。

<p:dataTable widgetVar="dataTableWV" value="..." var="...">

将widgetVar 也提供给您的p:tabView，例如tabViewWV。

<p:tabView widgetVar="tabViewWV">

将呼叫添加到applyRowChangesMassUpdate：

<p:remoteCommand name="applyRowChanges" actionListener="#{dealManagedBean .applyRowChangesMassUpdate}" />

然后使用这个脚本：

<script>
    $(document).ready(function() {
    //bind a function on table value changes
    dataTableWV.tbody.context.onchange = function() {
        //disable the tab you want by index, assuming the tab
        //is the second one, its index will be '1'
        tabViewWV.disable(1);

        //selects view back to the first tab.
        tabViewWV.select(0);

        //call the 'remoteCommand' function
        applyRowChanges();
    }
    });
</script>

这样，rowEdit 事件就不再需要了，所以只需删除

<p:ajax event="rowEdit" listener="#{dealManagedBean.applyRowChangesMassUpdate}"  update=":tbVUpdateDeals:tbVSelRates" />

你也可以删除

conRatesTabDisabled = true;
tabIndex = 1;

来自applyRowChangesMassUpdate 方法，随着选项卡被禁用，视图被移动到另一个带有客户端代码的选项卡，当需要查看问题时，这比服务器端代码更好。
