AS3 遍历对象

as3遍历对象所有属性的方法

1:

ObjectUtil.getClassInfo(this._arr[0]).properties as Array

 
2:

var o:Object=new Object();
o.name='mm';
o.type='size';
o.size='32D';
for (var i:String in o)
{
trace(i);
trace(o[i]);
}

3:

flash.utils.describeType

{
public class Resume
{
private var _name : String ="NAME";
private var _sex : String ="SEX";
private var _age : String="AGE";
private var _timeArea : String="TIMEAREA";
private var _company : String="COMPANY";

public function Resume(){
super(); 
}

public function get name():String
{
return _name;
}
public function get sex():String
{
return _sex;
}
public function get age():String
{
return _age;
}
public function get timeArea():String
{
return _timeArea;
}
public function get company():String
{
return _company;
}
}
} 

 var resume:Resume = new Resume();
var xml:XML = describeType(resume);
trace("xml : "+xml.toXMLString());//遍历转换xml格式的数据
trace("/////////////////////////////////////////////////////////////////");
for(var i:int =0;i<xml.accessor.length();i++){
trace("name :"+xml.accessor[i].@name);//获取类的属性名
trace("value : "+resume[xml.accessor[i].@name]);//获取类属性值

可以使用ObjectUtil类的getClassInfo函数
代码如下：

public static function copyProperty(objTo:Object, objFrom:Object):void{ 
if(objTo == null || objFrom == null) return; 

var claInfo:Object = ObjectUtil.getClassInfo(objTo); 
var props:Array = claInfo["properties"]; 
for each(var q:QName in props){ 
try{ 
if(objFrom.hasOwnProperty(q.localName)){ 
objTo[q.localName] = objFrom[q.localName]; 
} 
}catch(err:Error){} 
} 
} 

 

通过ObjectUtil.getClassInfo(obj)获取某个对象的类信息,类的属性和方法都放在返回的对象的'properties'属性数组中，通过遍历该数组就可以遍历类的属性和方法，
