AS3事件侦听器时数据被改变？ [英] AS3 Event listeners when data is changed?

问题描述

希望你能原谅我，如果这是一个简单的/愚蠢的问题。我开始学习动作脚本大约6天前，已经工作的一个小项目：D

Hopefully you will excuse me if this is a simple/silly question. I started learning action script about 6 days ago and already working on a small project :D

反正，有一种改变偶尔以反映在一个游戏（object._I._M.text）一个水平的名称属性。这可能需要一分钟改变，或者最多两分钟，这取决于所有球员的速度有多快能够完成的水平。

Anyways, there is a property that changes occasionally to reflect the name of a level in a game (object._I._M.text). It could take a minute to change, or a max of two minutes, depending on how fast all players are able to finish the level.

我希望能够聆听到这个属性的改变火了另一功能。我发现很少有这样的答案在网上，我已经找到了例子是非常不完整，写得不好。有谁知道我能做到这一点？

I want to be able to listen for the change in this property to fire off another function. I have found very few answers to this online, and the examples I have found were very incomplete and poorly written. Does anyone know how I could do this?

我已经试过......

I have tried ...

theobject._I._M.addEventListener（Event.CHANGE，MyFunction的）;

theobject._I._M.addEventListener(Event.CHANGE, myfunction);

要没有成功。感谢您的任何帮助或建议，我要回去学习，而我在等待着回应：D

To no success. Thanks for any help or advice, I am going to get back to learning while I await responses :D

推荐答案

我可能会使用getter / setter方法​​，或者只是声明了一个方法来改变文本框的文本，以便你可以每次分派事件。

I would probably use getters/setters, or just declare one method to change the text of that textfield so that you can dispatch an event every time.

function changeLevel(text:String):void {
   levelTf.text=text;
   dispatchEvent(new Event("levelChange"));
}
