您好 我有2个mxml文件....

CustComp.mxml

<mx:LinkButton id="linkbutton" label="ClickMe"  click="onLinkClicked()" mouseOver="onMouseOver()" mouseOut="onMouseOut()" />

private function onLinkClicked():void{
dispatchEvent(new CustomEvent("onClick");}
private function onMouseOver(event:CustomEvent):void{
dispatchEvent(new CustomEvent("onMouseOver");}
private function onMouseOut(event:CustomEvent):void{
dispatchEvent(new CustomEvent("onMouseOut");}

Main.mxml

var customComp:CustComp = new CustComp();
customComp.addEventListener(CustomEvent.MOUSE_CLICK1,onLinkClicked111);
customComp.addEventListener(CustomEvent.MOUSE_OVER1,onMouseOver111);
customComp.addEventListener(CustomEvent.MOUSE_OUT1,onMouseOut111);

private function onLinkClicked111(event:CustomEvent):void{
trace("click event");}
private function onMouseOver111(event:CustomEvent):void{
trace("mouse over event");}
private function onMouseOut111(event:CustomEvent):void{
trace("mouse out event");}

当我在组件中的链接按钮上鼠标悬停或鼠标移出时,事件将被分派到main.mxml并且各个函数被完美地调用。但是当我单击按钮时,onLinkClicked111()函数被调用一次和onMouseOut111(),onMouseOver111()被反复调用,直到我让光标远离链接按钮。   请帮助我,因为我应该怎样做以确保当我点击时,只有onLinkclicked111()函数应被调用而不是mouseOver111()或mouseOut111()

不确定你真正需要什么,但这里是简化的例子

    <fx:Script>
        <![CDATA[

                addEventListener("onClick", onClickHandler);
                addEventListener("onMouseOver", onMouseOverHandler);
                addEventListener("onMouseOut", onMouseOutHandler);
            }           


            private function onClickHandler(e:Event) : void
            {
                trace("onClick Handled");
            }

            private function onMouseOverHandler(e:Event) : void
            {
                trace("onMouseOver Handled");
            }

            private function onMouseOutHandler(e:Event) : void
            {
                trace("onMouseOut Handled");
            }


            private function onLinkClicked():void
            {
                dispatchEvent(new Event("onClick"));
            }

            private function onMouseOver(event:MouseEvent):void
            {
                if (!event.buttonDown)
                {

                }
            }

                {
                dispatchEvent(new Event("onMouseOut"));
                }
            }
