获取错误类型 1061:通过静态类型的引用调用可能未定义的方法 addEventListener [英] Getting error Type 1061: Call to a possibly undefined method addEventListener through a reference with static type

问题描述

我将我的代码从我的应用程序移到一个单独的 AS 类文件，现在我收到以下错误:

I moved my code from my Application to a separate AS class file and now I'm getting the following errors:

1061: Call to a possibly undefined method addEventListener through a reference with static type Class.

1180: Call to a possibly undefined method addEventListener.

.

package managers {


    import flash.events.Event;
    import flash.events.EventDispatcher;

    public class RemoteManager extends EventDispatcher {


        public function RemoteManager() {

        }


        public static function init(clearCache:Boolean = false):void {

            addEventListener(SETTINGS_CHANGE, settingChangeHandler);
            addEventListener(ITEMS_UPDATED, itemsUpdatedHandler);
        }
    }
}

推荐答案

您的代码

addEventListener(SETTINGS_CHANGE, settingChangeHandler);

评估为

this.addEventListener(SETTINGS_CHANGE, settingChangeHandler);

在静态方法中没有 this，因为它被设计为在没有实例的情况下运行.此外，您不能从静态类附加事件侦听器和调度事件.

There is no this in a static method, since it's designed to function without an instance. Furthermore, you cannot attach an event listener and dispatch events from a static class.

将您的函数声明更改为

public function init(clearCache:Boolean = false):void

或者实现一个单例模式来获得一个静态类，它调度事件".

Or implement a singleton pattern to kinda get a "static class, that dispatches events".

单身与事件管理.
