ActionScript 学习: 原来Flash这么用都可以 啊

机器上装了FLASH MX2004 ,一直没有使用,今天看了下,发现完全不会用,算了,还是慢慢来吧,这里做了个小例子,动态加载图片的,很郁闷啊

var mc:MovieClip;
var arr:Array;
var bool:Boolean;
var num3:Number;
var obj:Object;
var str:String;
_root.createTextField("results",2,100,100,300,300);
with(results){
	text = "色色学习ActionScript -- vb2005xu.iteye.com";
	text += "\ntype MovieClip :"+(typeof MovieClip(str)); // 返回 null
	text += "\ntype object :"+(typeof Object(str)); // 返回 object
	text += "\ntype Array :"+(typeof Array(num3)); // 返回 object
	text += "\ntype Boolean :"+(typeof Boolean(mc)); // 返回 boolean
	text += "\ntype String :"+(typeof String(mc)); // 返回 string
	text += "\ntype Number :"+(typeof Number(obj)); // 返回 number
	text += "\ntype Function :"+(typeof Function(mc)); // 返回 object
	text += "\ntype null :"+(typeof null(arr)); // 返回 undefined
	text += "\ntype undefined :"+(typeof undefined(obj)); // 返回 undefined
}
