访问itemRenderer中的XML节点 [Bindable]public var headingData1:Object=new Object（）； 私有函数getHeadings（evt:ResultEvent）：void{ //show（xmlData.toString（））； xmlData=evt.result； headingData1=xmlData.root.CIT； }

组合框作为Flex Advanced Datagrid中的itemRenderer

[Bindable]public var headingData1:Object = new Object();

<mx:HTTPService id="srv" url="components.xml" resultFormat="object" result="getHeadings(event);"/>

private function getHeadings(evt:ResultEvent):void{
             //Alert.show(xmlData.toString());
             xmlData = evt.result;
             headingData1 = xmlData.root.CIT;
    }

我需要在组合框中获取linkname值

观察：为什么要将headingData1实例化为对象？您正在向它提供一个XML，因此它应该被类型化为XML

这可能是您唯一的实际问题：

---

headingData1=xmlData.root.CIT

可能需要是

headingData1=xmlData.root.CIT[0]

（在使用XML时，我必须经常这样做，这与E4X的工作方式有关，甚至在该级别只有一个节点的情况下似乎也会使用XMLList。我听过其他解释，但这对我来说是有意义的。）

它不起作用，组合框在Advanced Datagrid中。组合框显示什么？什么都没有，它甚至不会加载到Advanced Datagrid中。我还更新了我的高级DataGrid代码它在第四行（备注/评论/改进区域）是否显示正确的值？如果是，请参阅我的更新代码-更改了数据提供程序。这只是一个文本输入，在这里输入，现在我将组合框中的值作为对象对象获取。但不是预期的值。
