，點擊時如何讓按鈕消失？

Question

我試圖讓一個按鈕消失後，點擊按鈕本身顯示在它下面的圖層。它可以有任何影響，爲了做到這一點，我只是需要它變得透明或脫離屏幕。幫幫我？

Answer 1

如果你有一個名爲「myButton的」按鈕：

//listen for mouse clicks 
myButton.addEventListener(MouseEvent.CLICK, mouseHandler); 

//handle mouse clicks 
function mouseHandler(event:MouseEvent):void 
{ 
    //stop listening for clicks 
    myButton.removeEventListener(MouseEvent.CLICK, mouseHandler); 
    //make button invisible 
    myButton.visible = false; 
} 

這將使按鈕瞬間消失在單擊時。如果您想應用淡入淡出效果...

myButton.addEventListener(MouseEvent.CLICK, mouseHandler); 

function mouseHandler(event:MouseEvent):void 
{ 
    myButton.removeEventListener(MouseEvent.CLICK, mouseHandler); 
    addEventListener(Event.ENTER_FRAME, fadeOut); 
} 

function fadeOut(event:Event):void 
{ 
    var a:Number = myButton.alpha-0.05; 
    if (a<=0) 
    { 
     a = 0; 
     removeEventListener(Event.ENTER_FRAME, fadeOut); 
    } 
    myButton.alpha = a; 
}
