Flash ActionScript 3.0卸载SWF

Question

所以我想卸载我的第一个SWF之前加载第二个SWF 当我加载SWF的时候我的问题是第二个SWF是第一个SWF的堆栈 当我从第二个SWF回到第一个声音播放时也会堆叠 和第一SWF动画仍然可以看到第二个SWF

1St.SWF代码：

var pausePoint:Number = 0.00; 
var aPlaying:Boolean; 
var soundChannel:SoundChannel = new SoundChannel(); 
var sound:Sound = new Sound(new URLRequest("home.mp3")); 

soundChannel = sound.play(0,999); 
aPlaying = true;  
    var loader:Loader = new Loader(); 
    addChild(loader); 

    btnInfo.addEventListener (MouseEvent.CLICK, loadInfo); 
    function loadInfo(event : MouseEvent): void{ 
     removeChild(loader); 
     loader.unloadAndStop(); 
     var SWFRequestInfo:URLRequest = new URLRequest("2nd.swf"); 
     loader.load(SWFRequestInfo); 
     addChild(loader); 
    } 

2nd.SWF代码：

var loader:Loader = new Loader(); 
addChild(loader); 

btnBack.addEventListener (MouseEvent.CLICK, loadBack); 
function loadBack(event : MouseEvent): void{ 
    removeChild(loader); 
    loader.unloadAndStop(); 
    var SWFRequestBack:URLRequest = new URLRequest("1st.swf"); 
    loader.load(SWFRequestBack); 
    addChild(loader); 
} 

它有没有解决这个问题的解决方案？

//main.swf

const FIRST:int = 1; 
const SECOND:int = 2; 
var current:int; 
var loader1:Loader = new Loader(); 
var loader2:Loader = new Loader(); 
addChild(loader1); 
addChild(loader2); 
addEventListener(LoadEvent.LOAD_SWF, loadSWF); 
trace("first Load"); 
loader2.visible=false; 
loader1.visible=false; 
loader1.load(new URLRequest("1.swf")); 
loader1.visible=true; 
current=FIRST; 

function loadSWF(event:LoadEvent):void 
{ 
    if(current == FIRST){ 
     current=SECOND; 
     loader2.load(new URLRequest(event.url)); 
     loader2.visible=true; 
     trace("loader2 Loaded"); 
     loader1.unloadAndStop(true); 
     loader1.visible=false; 
     trace("loader1 Unloaded"); 
    } 
    else{ 
     current=FIRST; 
     loader1.load(new URLRequest(event.url)); 
     loader1.visible=true; 
     trace("loader1 Loaded"); 
     loader2.unloadAndStop(true); 
     loader2.visible=false; 
     trace("loader2 Unloaded"); 
    } 

} 

1.swf

function clickNext(event:MouseEvent):void{ 
    trace("next clicked"); 
    dispatchEvent(new LoadEvent(LoadEvent.LOAD_SWF, "2.swf")); 
} 

2.swf

function clickPrev(event:MouseEvent):void{ 
    trace("prev clicked"); 
    dispatchEvent(new LoadEvent(LoadEvent.LOAD_SWF, "1.swf")); 
} 

LoadEvent.as

package { 
    import flash.events.Event; 
    public class LoadEvent extends Event { 

     public static const LOAD_SWF:String = "LoadSWF"; 

     public var url:String; 

     public function LoadEvent(type:String, url:String,bubbles:Boolean=true, cancelable:Boolean=false) { 
      super(type,bubbles,cancelable); 
      this.url=url; 
     }  

     public override function clone():Event 
     { 
      return new LoadEvent(type,url,bubbles,cancelable); 
     } 

    } 

} 

Answer 1

制作3-rd（主）SWF，它将加载/卸载第1个和第2个SWF。当您点击btnBack或btnInfo时，您可以发送一些事件。您可以捕获主SWF中的此事件并卸载当前的SWF并加载下一个SWF。

UPDATE

这是主要的SWF的代码：

const FIRST:int = 1; 
const SECOND:int = 2; 
var current:int; 

var loader:Loader = new Loader(); 
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadedHandler); 
addChild(loader); 
loadFirst(); 

function loadedHandler(event:Event):void 
{ 
    loader.content.addEventListener(Event.CLOSE, closeHandler); 
} 

function closeHandler(event:Event):void 
{ 
    if (current == FIRST) 
    { 
     loadSecond(); 
    } 
    else if (current == SECOND) 
    { 
     loadFirst(); 
    } 
} 

function loadFirst():void 
{ 
    if (loader.content) 
    { 
     loader.unloadAndStop(true); 
    } 
    current = FIRST; 
    loader.load(new URLRequest("1st.swf")); 
} 

function loadSecond():void 
{ 
    if (loader.content) 
    { 
     loader.unloadAndStop(true); 
    } 
    current = SECOND; 
    loader.load(new URLRequest("2nd.swf")); 
} 

下一个代码是从1-ST和在MouseEvent.CLICK处理程序中的2-ND SWF分派：

dispatchEvent(new Event(Event.CLOSE));
