Laya 监听龙骨动画播放完毕

this.skeleton = new Laya.Skeleton();
this.skeleton.pos(Laya.stage.width / 2, Laya.stage.height / 2);
this.skeleton.load("UIRes/main/dh_ndbs.sk", Laya.Handler.create(this, function () {
    xxxxx.addChild(this.skeleton);
    var num = this.skeleton.getAnimNum();
    let name = this.skeleton.getAniNameByIndex(num - 1);
    this.skeleton.play(name, false);
    this.skeleton.on(Laya.Event.STOPPED, this, function () {
        //xxxxx
    });
}));
//是否循环的判断监听，不太一样
//this.skeleton.on.play(name, true)
//this.skeleton.on(Event.COMPLETE, this, function(){

//});
