Question

如何使用AS3的加载器类将图像加载到带有事件处理程序的按钮上？以下是我的开始。下面是我点击邮件时收到的错误。

AS

//call function that starts loading my image
callButtons();


function callButtons():void {       
        var spanish_url = root_path + "spanish.png";
        var spanish_loader = new Loader();
        spanish_loader.load (new URLRequest(spanish_url));

//on load complete call the spanishLoaded function

        spanish_loader.contentLoaderInfo.addEventListener (Event.COMPLETE, spanishLoaded);  
}


//add loaded image to my main_container set x,y and turn it into a button. 

    function spanishLoaded (e:Event):void {
        var my_spanish:Loader = Loader(e.target.loader);    
        my_spanish.x = 1062;
        my_spanish.y = 620;
        main_container.addChild(my_spanish);
        my_spanish.addEventListener (MouseEvent.CLICK, playSpanish);
    }

function playSpanish (){

        trace("IN SPANISH");
}

当我点击舞台上的spanish.png时，我得到的错误是：ArgumentError: Error #1063: Argument count mismatch on MyVideoPlayer_CS4_fla::MainTimeline/playSpanish(). Expected 0, got 1.

我需要添加evt：MouseEvent

Answer 1

在您的函数spanishLoaded中添加一个事件监听器：

my_spanish.addEventListener (MouseEvent.CLICK, playSpanish);

playSpanish函数会发生鼠标事件：

你有：

function playSpanish ()

这应该是：

function playSpanish (event:MouseEvent)

使用loader添加图像，使图像成为带事件处理程序的按钮
