你好,我照着这个做了

2, 修改FLEX的MXML

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" initialize="init()" mouseOver="getMouseTarget(event)" >

private var mouseTarget:DisplayObject;
function init()
{
ExternalInterface.addCallback("openRightClick", openRightClick);
}


function getMouseTarget(event:MenuEvent):void
{
mouseTarget = DisplayObject(event.target);
}

function openRightClick():void
{
var e:MouseEvent = new MouseEvent(MouseEvent.MOUSE_DOWN, true, false, mouseTarget.mouseX, mouseTarget.mouseY);
mouseTarget.dispatchEvent(e);
}

function showMouseEvent(event)
{
if(event.buttonDown == true)
  Alert.show("Left");
else
  Alert.show("Right");
}

就是这个中老报错误 <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" initialize="init()" mouseOver="getMouseTarget(event)" >
错误如下:flash.evengts.mouseevent类型值的隐式强制指令的目标是非相关类型mx.events:menue
