我有这个MouseEvent函数，我完全不知道为什么它会被解雇两次。有没有办法可以在一段时间内禁用该功能？我尝试禁用按钮，但似乎直接调用了该功能，并且不会从按钮触发。
添加信息：当我向数组中添加更多对象时，该函数会触发更多时间

我强烈建议不要做某种标记或计时器黑客来解决一个无法解释的行为 - 这会导致代码膨胀，从长远来看会导致更多问题。
了解为什么它会两次调用你的函数要好得多。花时间搞清楚（你有没有设置多个显示对象的听众？这是一个冒泡的问题吗？它可能是你的鼠标？尝试一个干净的flash项目，只需一个处理程序，看看是否有两次调用，等等） ，并且您的代码不仅会更好更快，而且您在此过程中也会学到很多东西。
答案 1 :(得分：0)
您可以创建一个变量，因此它只运行一次。有点像...
var runOnce:Boolean = false;
button.addEventListener(MouseEvent.CLICK, testEvent);
function testEvent(e:Event):void{
if(runOnce == false){
//do stuff here
runOnce = true;
}
这有点懒，但你明白了。
