微信小程序单例报错

Creator 2.x
#1

开发时web测试正常，打包到微信小程序报错
单例写法如下
private static battleController: BattleController = null;

public static getBattle() {
    return battleController;

}

onLoad() {

    battleController = this;

}

微信小程序报错
battleController is not defined

#2

BattleController.battleController = this;
