Flash与JS之间相互调用以及参数传递

import flash.text.TextField;  
var param1:uint = 20;  
var param2:uint =17;  
 
var result:uint = ExternalInterface.call("addNumbers", param1, param2);  
 
function callMe(str:String):void{  
//outtext.text=str;  
var outtext:TextField=new TextField();  
outtext.text=str;  
addChild(outtext);  
trace(outtext);  
    //return "busy signal";  
}  
ExternalInterface.addCallback("myFunction", callMe); 

自动发布后 在HTML文件里添加下面代码：  
function addNumbers(num1, num2)  
   {  
    document.write(num1+num2);  
    return (num1 + num2);  
   }  
document.getElementById("ExternalInterface").myFunction("successfull");
