Question

[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;
    }


 <CIT id="1" name="CIT" projectname="CSI" projectmonth="March" manager="KingKong" description="Hello Kong">
    <component number="1" title="Title One">
                <link linkname="Excellent" value="5"/>
                <link linkname="Very Good" value = "4"/>
                <link linkname="Good" value = "3"/>
                <link linkname="Fair" value = "2"/>
                <link linkname="Poor" value = "1"/>
    </component>
</CIT>

组合框作为Flex Advanced Datagrid中的itemRenderer

我需要在组合框中获取linkname值。

我的高级数据网格

Answer 1

<mx:ComboBox dataProvider="{data.link}" 
    xmlns:mx="http://www.adobe.com/2006/mxml" labelField="@linkname">

Answer 2

观察：为什么要将headingData1实例化为对象？你正在为它提供一个XML，因此它应该被输入为XML。

这可能是您唯一的实际问题： headingData1 = xmlData.root.CIT可能需要headingData1 = xmlData.root.CIT[0]（我必须经常在使用XML时这样做，它与E4X如何工作有关，并且即使在该级别只有一个节点时似乎也使用XMLList。我听过其他的解释，但这个对我有用。）
