我在使用 clientListener 处理公开事件时遇到问题。每当用户离开 panelTabbed 中的选项卡时，我都会尝试显示确定/取消弹出窗口。

以下是代码：（这与 Oracle ADF 代码角提供的完全相同的代码）

     <af:resource type="javascript">
    function alertTabSwitch(disclosureEvent){
        var tab = disclosureEvent.getSource();           
        if(tab.getDisclosed()==false){

           var popup = tab.findComponent('p1');
           popup.show();
           popup.setProperty("tabToOpen",tab.
           disclosureEvent.cancel();
        }           
    }

    function handlePopupOkCancel(actionEvent){      
        var popupButton = actionEvent.getSource();
        var butPressed = popupButton.getProperty('popupAction'); 
        var dialog = popupButton.getParent();
        var popup  = dialog.getParent();
        if(butPressed == 'OK'){             
            var tabToFindAndFocusOnString = popup.getProperty("tabToOpen");
            if(tabToFindAndFocusOnString.length > 0){
              var tab = AdfPage.PAGE.findComponentByAbsoluteId(tabToFindAndFocusOnString);
              tab.setDisclosed(true);
              actionEvent.cancel();  
              popup.hide();       
            }
        }
        else{
            //close popup and stay on page
            actionEvent.cancel();    
            popup.hide();               
        }
    }
</af:resource>

                        <af:commandButton text="CANCEL" id="cb2" partialSubmit="true">
                             <af:clientAttribute name="popupAction" value="CANCEL"/>
                            <af:clientListener method="handlePopupOkCancel" type="action"/>
                        </af:commandButton>
                    </af:panelGroupLayout>

                <af:outputText value="Do you really want to switch tabs?" id="ot1"

            </af:dialog>
            <af:clientAttribute name="tabToOpen" value=""/>
        </af:popup>
    </f:facet>
</af:panelStretchLayout>

一切都在客户端完成。当我单击一个选项卡时，首先会为所选选项卡触发“取消选择”事件，并且该选项卡的公开值更改为 false。更改值后，将调用侦听器。因此，在 javascript 中，单击 OK 按钮后会再次显示相同的选项卡。如果在调用 af:clientListener 之前没有更改值，则不会发生此问题。

有人可以帮我吗？

我在这里更彻底地描述了这个问题。 https://forums.oracle.com/message/11227277#11227277

将标签更改为以下内容，它会起作用，这是针对 11.1.1.7 进行测试的

<af:resource type="javascript">

var theTabToClose;
var theTabToOpen;
function alertTabSwitch(disclosureEvent){
    var tab = disclosureEvent.getSource();   //This is the tab to close
    if(tab.getDisclosed()==false){
       theTabToClose = tab;
       theTabToOpen = disclosureEvent.getDisclosureCounterpart();
       var popup = tab.findComponent('p1');
       disclosureEvent.cancel();
       popup.show();
    }            
}

function handlePopupOkCancel(actionEvent){      
    var popupButton = actionEvent.getSource();
    var butPressed = popupButton.getProperty('popupAction'); 
    var dialog = popupButton.getParent();
    var popup  = dialog.getParent();

    if(butPressed == 'OK'){     
        theTabToOpen.setDisclosed(true);
    }else{
        theTabToClose.setDisclosed(true);
    }
        actionEvent.cancel();
        popup.hide();
}
</af:resource>
