一、目的

??? bb.swf的元件庫中有一個元件，在aa.swf中調用這個元件，顯示到舞臺上

二、步驟

?? bb.swf

??? 1.新建bb.fla，在上面畫一個圓

??? 2.選擇這個圓，將其轉換為元件，并選擇”Export for ActionScript”，類名取為”Yuan”

??? 3.在舞臺上刪除這個元件（刪除后，只在元件庫中有該元件）

??? 4.Ctrl+Enter 運行bb.fla ， 生成bb.swf

aa.swf

??? 1.新建aa.fla

??? 2.在時間軸上加如下代碼

????? var cl:ClassLoader = new ClassLoader(“bb.swf”);?? //加載bb.swf文件
????? cl.addEventListener(Event.COMPLETE, cm_fun);

????? function cm_fun(e:Event){
????????? var Yuan:Class = cl.getClass(“Yuan”) as Class;
????????? var yuan:DisplayObject = new Yuan();
????????? yuan.x = 50;
????????? yuan.y = 100;
????????? yuan.alpha = .5;
???
????????? addChild(yuan);
????? }

三、類加載文件

????? package {

??????? import flash.display.Loader;
??????? import flash.net.URLRequest;
??????? import flash.utils.ByteArray;
??????? import flash.events.Event;
??????? import flash.events.ProgressEvent;
??????? import flash.events.EventDispatcher;
??????? import flash.system.LoaderContext;

??????? public class ClassLoader extends EventDispatcher{
??
?????????? public var url:String;
?????????? public var loader:Loader;
??????????
?????????? //構造函數
?????????? public function ClassLoader(obj:Object = null,lc:LoaderContext = null) {
????????????? if(obj != null){
??????????????? if(obj is ByteArray){
????????????????? loadBytes(obj as ByteArray,lc);
??????????????? }else if(obj is String){
????????????????? load(obj as String,lc);
??????????????? }else{
????????????????? throw new Error(“參數錯誤，構造函數第一參數只接受ByteArray或String”);
??????????????? }
????????????? }
?????????? }
??
??????????? //加載
?????????? public function load(_url:String,lc:LoaderContext = null):void{
????????????? url = _url;
????????????? loader = new Loader;
????????????? loader.load(new URLRequest(url),lc);
????????????? addEvent();
??????????? }
??
?????????? //加載字節
?????????? public function loadBytes(bytes:ByteArray,lc:LoaderContext = null):void{
????????????? loader = new Loader;
????????????? loader.loadBytes(bytes,lc);
????????????? addEvent();
??????????? }
??
????????? //開始偵聽
??????????? private function addEvent():void{
????????????? loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS,progressFun);
????????????? loader.contentLoaderInfo.addEventListener(Event.COMPLETE,completeFun);
??????????? }
??
??????????? //結束偵聽
??????????? private function delEvent():void{
????????????? loader.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS,progressFun);
????????????? loader.contentLoaderInfo.removeEventListener(Event.COMPLETE,completeFun);
?????????? }
??
??????????? //加載成功，發布成功事件
??????????? private function completeFun(e:Event):void {
????????????? delEvent();
????????????? dispatchEvent(e);
??????????? }
??
?????????? //加載過程
??????????? private function progressFun(e:ProgressEvent):void{
????????????? dispatchEvent(e);
??????????? }
??
??????????? //獲取定義
??????????? public function getClass(className:String):Object {
????????????? return loader.contentLoaderInfo.applicationDomain.getDefinition(className);
?????????? }
??
?????????? //是否含有該定義
??????????? public function hasClass(className:String):Boolean {
????????????? return loader.contentLoaderInfo.applicationDomain.hasDefinition(className);
??????????? }
??
??????????? //清除
?????????? public function clear():void{
????????????? loader.unload();
????????????? loader = null;
?????????? }
???????? }
??????? }
