好像Flex3也没有找到可以直接使用的(x,y)的方法来指定Alert窗口的显示位置。但是还是有办法解决这个问题的：

代码1:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
  <![CDATA[
    import mx.controls.Alert;
    import mx.managers.PopUpManager;
    private function showAlert():void{
        var alert:Alert = Alert.show("Can you see me on random positions?");
             PopUpManager.centerPopUp (alert);
             var newX:Number = 200;
             var newY:Number = 200;
             callLater (alert.move, [newX, newY]);
    }
  ]]>
</mx:Script>
<mx:Button label="Show Alert" click="showAlert()"/>
</mx:Application>

代码2：只更改showAlert()方法

private function showAlert():void{
      var alert:Alert = Alert.show("Can you see me on random positions?");
           PopUpManager.centerPopUp (alert);
           var newX:Number = 200;
           var newY:Number = 200;
           //alert.validateNow();

           alert.move(newX,newY);
           //callLater (alert.move, [newX, newY]);
}

代码3：添加即时验证：

private function showAlert():void{
      var alert:Alert = Alert.show("Can you see me on random positions?");
           PopUpManager.centerPopUp (alert);
           var newX:Number = 200;
           var newY:Number = 200;
           alert.validateNow();
           alert.move(newX,newY);
           //callLater (alert.move, [newX, newY]);
}
