as3声明一个eventListener - 变量范围

Question

如何声明Event Listener为公共状态，以便它可用于所有功能？

// 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

打开该嵌套事件侦听到公共函数的函数：

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