Question

flex中httpservice调用本工程的books.xml后显示不出结果，添加了<fx:declarations></fx:declarations>

是用send()连接的，程序如下：
<?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" creationComplete="init()">
<fx:Script>
<![CDATA[
import mx.collections.*;
import mx.rpc.events.*;
public var books:ArrayCollection;
private function init():void
{

bookDataIn.send();
}
private function bookHandler(event:ResultEvent):void
{
books=event.result.books.stock;
}
]]>
</fx:Script>

<s:layout>
<s:BasicLayout/>
</s:layout>
<fx:Declarations>

<s:HTTPService id="bookDataIn" url="ja/books.xml" result="bookHandler(event)" resultFormat="e4x">
</s:HTTPService>

</fx:Declarations>
</s:Application>

Answer 1

调试看看，是否调用成功了？ 如果调用成功，就看看你books.xml的event.result.books.stock;是否有值。。

Answer 2

界面上什么都没有，你想看到显示什么？
