Object与Dictionary的区别

看看这两端代码就知道了:

object的输出:

var a:Object = new Object();var b:Object = new Object();var c:Object=new Object()var obj:Object = new Object();obj[a] = 1;// obj["[object Object]"] = 1;    obj[b] = 2;// obj["[object Object]"] = 2;    obj[c] = 3;// obj["[object Object]"] = 2; for (var prop:String in obj){	trace(prop);// traces: [object Object]    	trace(obj[prop]);// traces: 2    }

 Dictionary的输出:

import flash.utils.Dictionary; var a:Object = new Object(); var b:Object = new Object(); var dict:Dictionary = new Dictionary(); dict[a] = 1; // dict[a] = 1; dict[b] = 2; // dict[b] = 2; for (var prop:* in dict) {       trace(prop); // traces: [object Object], [object Object]       trace(dict[prop]); // traces: 1, 2 }
