--JAVASCRIPT TRANSFER METHOD OF FLEX
 FLEX FILE
  1,ExternalInterface.addCallback("myFlexFunction",myFun); myFun为FLEX中的函数名,这是一个key-value结构
 JAVASCRIPT FILE
  1,页面中包含swf文件,OBJECT中指定swf文件的id
  2,使用OBJECT中指定的ID.key来调用FLEX中的方法,FLEX专属的一些特性不能被使用,例如Alert.show();

    Alert.show("20 from flex","MEssage");
    return 20;

   private function initApp():void{
    ExternalInterface.call("myFun",1,2); //传入参数
    ExternalInterface.addCallback("myFlexFunction",myFun);
   }
