Question

我有一个叫做“currentMystery”的var我把这个问题简化为这两个函数我相信。无论如何，第一次通过它工作并跟踪一个数组中的变量......但第二次通过某些东西将其更改为[Event type =“soundComplete”bubbles = false cancelable = false eventPhase = 2]

代码中有什么改变这个或我做错了什么？非常感谢！

关于如何将其保持为与此处指定的相同var的任何想法：

currentMystery = "" + Mystries[4] + "";

...

public static var Mystries:Array = new Array("null","Joyful","Luminous","Sorrowful","Glorious");

    public function checkDecade(e:Event = null)
    {
        if (decadeCount < 6)
        {
            Announce = true;
            currentMystery = "" + Mystries[4] + "";
            prayDecade(currentMystery);

        }
    }


    public function prayDecade(currentMystery:String)
    {

  //// MY ISSUE IS WITH currentMystery. First time through 
  //// it works but the second through it is changing to 
  //// something like [Event type="soundComplete" bubbles=false etc...
  trace("Pray Decade called: " +currentMystery);


        if (Announce)
        {
            /// Sets PAUSE before Announc || Add features later to all prayers
            setTimeout(function()
               {
                    MainDoc.cPrayer.text = currentMystery;
                    trace("Called Announce"+decadeCount);
                    trace("Called Announce: Mystery: " + currentMystery+" Current Decade: " +decadeCount);
                    theAnnounce = new Sound();
                    theAnnounce.load(new URLRequest("audio/Rosary/Announce/"+currentMystery+"/"+decadeCount+".mp3"));
                    Praying = theAnnounce.play();
                    Praying.addEventListener(Event.SOUND_COMPLETE, prayDecade );
                    Announce = false;
                }, 2000);

        }
        else
        {
            if (prayerCount==0)
            {

                setTimeout(function()

                     Begin = true;
                     ourFather(); 
                   }, 2000);

Answer 1

代码中有什么改变这个或我做错了什么？

'SoundChannel'的事件处理程序错误。

Praying.addEventListener(Event.SOUND_COMPLETE, prayDecade );

在prayDecade中，作为参数将传递event object（Event.SOUND_COMPLETE），而不是您正在等待的字符串。所以[Event type="soundComplete" bubbles=false cancelable=false eventPhase=2]是事件的String表示。

Answer 2

您正在使用prayDecade方法作为声音完成事件的处理程序，并直接在您的代码中调用它。当它作为事件处理程序调用时，它接收的参数是一个事件对象，它被强制转换为string并覆盖本地（prayDecade函数）范围内的公共变量。

我认为如果您按如下方式更新函数，您将得到您期望的结果（假设currentMystery是类范围中的公共变量：

public function prayDecade(e:Event)
{
    trace("Pray Decade called: " + currentMystery);

    // ....
}

当您直接调用该方法时，请不要传递变量：

// Assuming currentDecade is in scope in the prayDecade method
prayDecade(/*currentMystery*/);

as3为什么我的公共变化？
