[AS3]as3和PHP程序的交互技巧整理(3)

btn.addEventListener(MouseEvent.CLICK,loadTxt);
function loadTxt(evt:MouseEvent):void
{
var urlLoader:URLLoader=new URLLoader();
urlLoader.load(new URLRequest("http://localhost/as3/xml.php"));
urlLoader.addEventListener(Event.COMPLETE,finish);
}
function finish(evt:Event):void
{
var mydatas:XML=XML((evt.currentTarget as URLLoader).data);
mytxt.text=mydatas.c1.toString()+","+mydatas.c2.toString();
}
php端:
<?
//你可以使用php操作xml的函数
//这里为了简单起见只是echo出来
echo "<?xml version=\"1.0\" encoding=\"utf-8\"?>";
echo "<cities>";
echo "<c1>北京</c1>";
echo "<c2>上海</c2>";
echo "</cities>";
?>
