多次为元件添加侦听事件!有没有问题?

复制内容到剪贴板

代码:

var i=1;
btn.addEventListener(MouseEvent.CLICK,click1);
btn.addEventListener(MouseEvent.CLICK,click2);
btn.addEventListener(MouseEvent.CLICK,click3);
function click1(e:MouseEvent){
    trace(i++);
}
function click2(e:MouseEvent){
    trace(i++);
}
function click3(e:MouseEvent){
    trace(i++);
}
