as3代码：

按钮名称.addEventListener(MouseEvent.CLICK,事件处理函数名称);

function 事件处理函数(event:MouseEvent):void

{

gotoAndStop();

}

将mc转成按钮使用
myMC.buttonMode=true;
myMC.addEventListener(MouseEvent.CLICK, fl_onClick);
myMC.addEventListener(MouseEvent.MOUSE_OUT, fl_onMouseOut);
var visited=false;

function fl_onClick(evt:MouseEvent):void {
    //your code here
    trace("Button clicked");
    //clicked, so page has been visited
    visited=true;
}

function fl_onMouseOut(evt:MouseEvent):void {
    if (visited) {
        myMC.gotoAndStop("visited");
    }
}

buttonMode = true;

addEventListener(MouseEvent.MOUSE_DOWN, startDragging);
addEventListener(MouseEvent.MOUSE_UP, stopDragging);
function starDragging(event:MouseEvent):void{
         event.target.startDrag(true);
        }
function stopDragging(event:MouseEvent):void{
        event.target.stopDrag();
        }
