当它到达最后一帧时从主屏幕卸载外部swf（子）？

Question

我有一个外部swf加载到主框架（URL请求），当swf到达它的最后一帧时，我需要它卸载它自己。我需要在CHILD swf上没有任何代码的情况下执行此操作，因为这是针对iOS应用程序的。谁能帮忙？

//start button 

start_button_aboriginal.addEventListener(MouseEvent.CLICK, fl_ClickToLoadUnloadSWF_3); 

import fl.display.ProLoader; 
var fl_ProLoader_3:ProLoader; 

//This variable keeps track of whether you want to load or unload the SWF 
var fl_ToLoad_3:Boolean = true; 

function fl_ClickToLoadUnloadSWF_3(event:MouseEvent):void 
{ 
if(fl_ToLoad_3) 
{ 
    fl_ProLoader_3 = new ProLoader(); 
    fl_ProLoader_3.load(new URLRequest("myths/myth_aboriginal.swf")); 
    addChild(fl_ProLoader_3); 
    fl_ProLoader_3.x = 114; 
    fl_ProLoader_3.y = 41; 
} 
else 
{ 
    fl_ProLoader_3.unload(); 
    removeChild(fl_ProLoader_3); 
    fl_ProLoader_3 = null; 
} 
// Toggle whether you want to load or unload the SWF 
fl_ToLoad_3 = !fl_ToLoad_3; 

//here, I want to UNLOAD the external SWF when it is finished playing. 

var totFrames:Number=childMC.totalFrames; 
var curFrame:Number; 

childMC.addEventListener(Event.ENTER_FRAME, remove); 

    function remove(evt:Event):void { 
    curFrame=childMC.currentFrame; 
    if (totFrames==curFrame) { 
     removeChild(childMC); 
    } 
}

您需要在全局范围内声明childMC并指定加载程序内容。 并且不声明函数内的函数！

像这样不TESTET

import fl.display.Loader; // impoerts belong at the top 

var fl_ProLoader_3:ProLoader; // then your global vars 
var childMC:MovieClip; // instatiate childMC with global scope 

start_button_aboriginal.addEventListener(MouseEvent.CLICK, fl_ClickToLoadUnloadSWF_3,false,0,false); // listener with weak refference 

var fl_ToLoad_3:Boolean = true; 

function fl_ClickToLoadUnloadSWF_3(event:MouseEvent):void 
{ 
if(fl_ToLoad_3) 
{ 
    fl_ProLoader_3 = new Loader(); 
    var url:URLRequest = new URLRequest("myths/myth_aboriginal.swf"); 
    var loaderContext:LoaderContext = new LoaderContext(false, ApplicationDomain.currentDomain, null); // IOS needs this 
     fl_ProLoader_3.load(url, loaderContext); 
    fl_ProLoader_3.addEventListener(Event.COMPLETE, loadCompleteHandler,false,0,false); 

} 
else 
{ 
    if(childMC){ 
      removeChild(childMC); 
      childMC.unloadAndStop(); 
      childMC = null; 
    } 

} 
// Toggle whether you want to load or unload the SWF 
fl_ToLoad_3 = !fl_ToLoad_3; 

} 
function loadCompleteHandler(evt:Event):void 
{ 
     childMC = evt.target.content as MovieClip; 
     childMC.addEventListener(Event.ENTER_FRAME, remove); 
     addChild(childMC); 
     childMC.x = 114; 
     childMC.y = 41; 
} 

function remove(evt:Event):void { 
    var totFrames:Number=childMC.totalFrames; 
    var curFrame:Number =childMC.currentFrame;; 

    if (totFrames==curFrame) { 
     childMC.removeEventListener(Event.ENTER_FRAME, remove); 
     removeChild(childMC); 
     childMC.unloadAndStop(); 
     childMC = null; 
    } 
}
