JS访问SWF的函数用法实例

import flash.external.;
var methodName:String = "SetImgPath";
//JS需要调用的函数名字
var instance:Object = null;
var method:Function = extractstr;
//Flash中实际的函数名字，参数忽略，你调用的时候要记得有参数的要加上
var wasSuessful:Boolean = ExternalInterface.addCallback(methodName, instance, method);
trace(wasSuessful+"-callback")
