플래시 의 안전 샌 드 박스 메커니즘 으로 인해 flex 가 클 라 이언 트 로 컬 파일 을 읽 을 때 어려움 이 많 습 니 다.js 를 빌려 기능 을 실현 해 야 합 니 다. 여기 서 ActionScript 와 javaScript 가 서로 호출 하 는 방법 을 요약 합 니 다.
 
1. Flex 엔 드 코드: test. MXML
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:ns1="*" creationComplete="initCall()">
<mx:Script>
	<![CDATA[
		import mx.controls.Alert;
		public function initCall():void{
			//     javaScript     
			ExternalInterface.addCallback("sendToActionScript",receivedFromJavaScript);
		}
		
		//   javaScript     
		private function receivedFromJavaScript(value:String):void {
			  Alert.show("JavaScript says: " + value + "
");
        }
       	
       	//  javaScript 
        public function transferJavaScript(){
        	ExternalInterface.call("sendToActionScript","ActionScript    1");
        }
	]]>
</mx:Script>	
	<mx:Button x="256" y="216" label="Button" click="transferJavaScript()"/>
</mx:Application>

    External Interface 의 addCallback 방법 은 js 에서 호출 된 이름 을 해당 하 는 as 방법 에 반영 합 니 다.
