Actionscipt_将字符串转换成类，函数，变量

转载：http://blog.csdn.net/dengxingbo/article/details/5775236

1.将字符串转换为类
       var classToConstruct:Class=getDefinitionByName("com.sig.ClassA") as Class;
       var s:ClassA =new classToConstruct();

2.将字符串转换为函数

        public var actionRef:String = "getit"

        protected function button1_clickHandler(event:MouseEvent):void
        {
             if (this.hasOwnProperty(actionRef))
                 this[actionRef]();

        }

        public function getit():void
        {
            Alert.show("i am click");
        }

3.将字符串转换成变量

        var object:Object = new Object();
        var value:int=10;

        for(var i:int = 1;i<3;i++){
             object["x"+i] =value;
             value++;
        }

        Alert.show(object.x1);
        Alert.show(object.x2);

调用本类的属性，可使用 this[variable_name]
