as3聲明一個eventListener - 變量範圍

Question

如何聲明Event Listener爲公共狀態，以便它可用於所有功能？

// Coded needed below to declare Event 

function addEventL() 
    { 
    /// Declares it in a function 
    myMovie.addEventListener(MouseEvent.CLICK, menuIn); 
    } 

function removeEventL() 
    { 
    /// This does not work because it was first called in a function. 
    /// So it can not find the event Listener to remove. 
    myMovie.removeEventListener(MouseEvent.CLICK, menuIn); 
    } 

Answer 1

打開該嵌套事件偵聽到公共函數的函數：

package example 
{ 
public function addEventL() 
{ 
/// Declares it in a function 
myMovie.addEventListener(MouseEvent.CLICK, menuIn); 
} 
}
