关于AS3中的removeEventListener

[wylog]

我在一个按钮上应用监听器，然后把一段动画应用到这个按钮上（滤镜效果).现在的问题是，我想在鼠标移出的时候，去掉这个效果，我尝试过移除监听器然后重新注册，但加载到按钮上的效果还是没有消失，为什么？

//动画序列；
var __motion_sc5:MotionBase;
if(__motion_sc5 == null) {
import fl.motion.Motion;
__motion_sc5 = new Motion();
__motion_sc5.duration = 15;

// Call overrideTargetTransform to prevent the scale, skew,
// or rotation values from being made relative to the target
// object's original transform.
// __motion_sc5.overrideTargetTransform();

// The following calls to addPropertyArray assign data values
// for each tweened property. There is one value in the Array
// for every frame in the tween, or fewer if the last value
// remains the same for the rest of the frames.

removeEventListener　时需要重设按钮效果吧

[nuhong]

代码好长，当remove的时候，设置filters=null.

[jesse_luzexi]

removeEventListener　里的参数 要包括你以前监听时的函数

[caonilaolaode]

效果加上去了，你移除的是按钮的事件监听器，并不是滤镜效果！当然就没有作用了！最简单的方法就是2楼所说，设置filters=null.

谢谢2楼的解答
