如何將孩子添加到flex 4中的手風琴兒童？

Question

我花了數小時試圖弄清楚這一點......任何幫助將不勝感激！

我有一個讀取生成手風琴編程容器的ArrayCollection：

<s:ArrayCollection id="_ac_ps"> 
     <fx:Object label="Block and lot" data="_blocklot" searchType="districtblocklot" info="" /> 
     <fx:Object label="Address" data="_address" searchType="singletxtstring" info=""/> 
     <fx:Object label="Owner name" data="_owner" searchType="singletxtstring" info=""/> 
     <fx:Object label="Advanced data mining" data="_advanced" searchType="advancedmining" info=""/> 
    </s:ArrayCollection> 

而且我這是怎麼產生的手風琴孩子：

for (var num1:int = 0; num1 <= _ac_ps.length - 1; num1++) 
        { 
         navContent = new NavigatorContent(); 
         navContent.percentWidth = 100; 
         navContent.percentHeight = 100; 
         navContent.label = _ac_ps[num1].label; 
         navContent.id = ""+_ac_ps[num1].data; 
         navContent.name = ""+_ac_ps[num1].data; 
         ////(""+navContent.id); 
         _searchAccordion.addChild(navContent); 
        } 

這工作得很好。現在我想要做的是基於手風琴中導航器內容的ID，添加孩子。例如，我想將一個Label類型的子元素添加到id爲「_blocklot」的navigatorContent中，但將一個textInput元素添加到id爲「_address」的navigatorContent對象中。

private function loadSearchControls():void 
     { 
      var accordionChildren:Array = _searchAccordion.getChildren(); 
      for each(var currentnavContent:NavigatorContent in accordionChildren) 
      { 
       Alert.show (""+currentnavContent.id, "currentnavContent.id"); 
       if (currentnavContent.id == "_blocklot") 
       { 

        try{ 
         var _label:Label = new Label(); 
         _label.text = "come on now!!!!!!"; 
         //SO HOW DO I CAPTURE THE ID SO THAT I CAN ADD THIS LABEL AS A CHILD??? 
         //_searchAccordion._blocklot.addChild(_label); does not work 

        } 
        catch(errorObj:Error) 
        { 
         Alert.show("nope"); 
        } 


       } 
       else if (currentnavContent.id == "_address") 
       { 
        Alert.show("bbb"); 
       } 
      }

這應該適合你。您已經確定currentNavContent是否是您想要的，所以只需將該控件添加到currentNavContent。

 private function loadSearchControls(event:MouseEvent):void 
     { 
      var accordionChildren:Array = _searchAccordion.getChildren(); 
      for each(var currentnavContent:NavigatorContent in accordionChildren) 
      { 
       Alert.show (""+currentnavContent.id, "currentnavContent.id"); 
       if (currentnavContent.id == "_blocklot") 
       { 

        try{ 
         var _label:Label = new Label(); 
         _label.text = "come on now!!!!!!"; 
         //SO HOW DO I CAPTURE THE ID SO THAT I CAN ADD THIS LABEL AS A CHILD??? 
         //_searchAccordion._blocklot.addChild(_label); does not work 
         currentnavContent.addElement(_label); 

        } 
        catch(errorObj:Error) 
        { 
         Alert.show("nope"); 
        } 


       } 
       else if (currentnavContent.id == "_address") 
       { 
        Alert.show("bbb"); 
       } 
      } 
     }
