Question

我正在一个小型摄影展上工作。我创建了一个Xml文档,试图将其与我的清单控制与项目供应商联系起来。然而,当我试图挽救档案时,我就无法获得未界定的财产“数据”错误。我认为,我们准备使用“数据”来指目前数据标的浏览量。我的法典就是这样。

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
      xmlns:s="library://ns.adobe.com/flex/spark" 
      xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
 <fx:Declarations>
  <fx:Model id="pictureXML" source="data/pictures.xml"/>
  <s:ArrayList id="pictureArray" source="{pictureXML.picture}"/>
 </fx:Declarations>



 <s:List id="pictureGrid" dataProvider="{pictureArray}" 
   horizontalCenter="0" top="20">
  <s:itemRenderer>
   <fx:Component>
    <s:HGroup>
     <mx:Image source="images/big/{data.source}" /> // where the error happen
     <s:Label text="{data.caption}"/> // where the error happen
    </s:HGroup>   

   </fx:Component>
  </s:itemRenderer>
 </s:List>


</s:Application>

My xml

<?xml version="1.0"?>
<album>
   <picture>
   <source>city1.jpg </source>
   <caption>City View 1</caption>
   </picture>
    <picture>
   <source>city2.jpg </source>
   <caption>City View 2</caption>
   </picture>
     <picture>
   <source>city3.jpg </source>
   <caption>City View 3</caption>
   </picture>
    <picture>
   <source>city4.jpg </source>
   <caption>City View 4</caption>

   <caption>City View 6</caption>
   </picture>
    <picture>
   <source>city7.jpg </source>
   <caption>City View 7</caption>
   </picture>
    <picture>
   <source>city8.jpg </source>
   <caption>City View 8</caption>
   </picture>
    <picture>
   <source>city9.jpg </source>
   <caption>City View 9</caption>
   </picture>
    <picture>
   <source>city10.jpg </source>
   <caption>City View 10</caption>
   </picture>
</album>

我欣赏任何帮助!

我认为,你试图获取的数据财产不属于范围,因为它属于在线项目。请将项目提交者总结成自己的组成部分,而不是将其作为在线组成部分。

您也可进入在线项目Renderer,以便查阅每个项目的数据财产,但这更清洁。

我把《国际公路货运公约》分离出来,一切似乎都是罚款的。

<!-- YOUR LIST -->
<s:List id="pictureGrid" dataProvider="{pictureArray}" 
                horizontalCenter="0" top="20"
                itemRenderer="TestRenderer"/> // reference new IR class here

<!-- NEW ITEMRENDERER CLASS -->
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009" 
            xmlns:s="library://ns.adobe.com/flex/spark" 
            xmlns:mx="library://ns.adobe.com/flex/mx" 
            autoDrawBackground="true">

        <s:HGroup>
            <mx:Image source="images/big/{data.source}" /> 
            <s:Label text="{data.caption}"/> 
        </s:HGroup>   

</s:ItemRenderer>

审判

 override public function set data(value:Object):void
   {
                super.data = value;
                if (data == null)
                    return;

                irImage.source = data.path; 
                            irText.text = data.caption   

  }


<s:HGroup>
            <mx:Image id="irImage" /> 
            <s:Label id="irText"text="{data.caption}"/> 
</s:HGroup>

如果这不可行,那就告诉我。
