ArrayCollection通過匹配項目循環

Question

我希望有人可以幫助我.....

我想建立一個問卷模塊的動態表單。建立一些以前的帖子我使用的過程類似於有問題的「How to generate a form(<mx:form>) dynamically in flex?」我已經設法證明了擴展XML以包括日曆，組合框等事實。

我的問題是，現在需要獲取來自ArrayCollection的數據而不是來自xml文件。我期待循環通過交流和類型=「文本」呈現textinput字段，其中類型=「日曆」呈現日曆等等

我的代碼到目前爲止只是看着一個textinput字段（和對不起所有的評論包括）是： -

[Bindable] 
    public var AC:ArrayCollection = new ArrayCollection([ 
    {type:'text', direction:'horizontal', tooltip:'test tooltip', label:'my textbox label', id:'1'}, 
      {type:'text', direction:'horizontal', tooltip:'another tooltip', label:'another label', id:'2'} 
    ]); 



    private function init():void 

    {  
     var form:Form = new Form(); 

      for each(var elements:String in AC) 

    { 
          switch(elements.@type.toString()) 
          { 
            case "text": 

        var fi:FormItem = new FormItem(); 
         // fi.toolTip = elements.tooltip.toString(); 
              // fi.required = getglobalprofile.required.toString(); 
              // fi.direction = getglobalprofileb[i].@direction; 

         var li:Label = new Label(); 
              // li.text = getglobalprofileb[i].@label; 
              // li.width = 100; 

         var ti:TextInput = new TextInput(); 
              ti.text = "test"; 
             ti.width = 200; 

         form.addChild(fi); 
         fi.addChild(li); 
         fi.addChild(ti); 

      //   break; 
          } 
      }  

        this.addChild(form); 
      } 

]]> 
    </mx:Script> 

<!-- Data grid added just to check that AC getting data--> 

<mx:DataGrid id="profile" selectedIndex="1" dataProvider="{AC}" width="100%" height="50%" /> 

    <mx:Form id="form" name="form"> 

    </mx:Form> 

，如果您有興趣使用XML版本（只用於呈現）讓我知道，我將在此以及

Answer 1

我已經找到了答案，這個問題的第一部分是通過一個簡單的請求使用RO調用來獲取表單。

下一個問題是如何獲得的形式保存時，我並不「知道」現場ID，有多少或什麼類型的字段它是.........

另一個帖子methinks！

希望這對某人有用。
