Actionscript3里面的函数静态变量

Question

我可以在动作3中这样做吗？在调用定时器功能时，应该只定义一次计数器

function timer(e:TimerEvent):void
{
    static var counter=1;
    trace("Times: " + counter );
}

Answer 1

怎么样：

function timer(e:TimerEvent):void
{
    this.counter = this.counter || 0;
    this.counter ++;
    trace("Times: " + this.counter );
}
