我是 flex 开发的新手,需要帮助。
我有一个 xml 文件,其中包含我想在用户更改任何内容时更新的数据,该文件保存在应用程序所在的本地程序文件中。
这是我读取 XML 文件的代码:
<fx:Declarations>
<s:HTTPService id="systemData" url="data/system.xml" method="POST"/>
</fx:Declarations>
<fx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
import mx.rpc.events.ResultEvent;
[Bindable]
private var systemInfo:Object = new Object();
private var interval:uint;
[Bindable]
private var xmlData:ArrayCollection = new ArrayCollection();
private function viewMain(event:Event):void
{
mainWindow.visible = true;
systemWindow.visible = false;
}
private function viewSystem(event:Event):void
{
mainWindow.visible = false;
systemWindow.visible = true;
}
public function init():void
{
systemData.addEventListener(ResultEvent.RESULT, getXML);
systemData.send();
interval = setInterval(reloadXML, 1800000);
}
private function getXML(e:ResultEvent):void
{
systemInfo = systemData.lastResult.system;
systemIP.text = systemInfo.systemip;
systemPort.text = systemInfo.systemport;
systemUsername.text = systemInfo.systemusername;
systemPassword.text = systemInfo.systempassword;
}
private function reloadXML():void
{
systemData.send();
}
