人, 我有一个关于在Flex中为现有对象添加其他名称 - 值对的问题;
我有一个Object Type的object1 我宣布一个新的object2 = object1加上一些额外的名称 - 值对, 有没有办法将新的名称 - 值对附加到现有对象?
非常感谢,

如果我正确理解你的问题,object2是object1的引用指针;因此,对object2的更改会影响object1:
package
{
import flash.display.Sprite;
public class X extends Sprite
{
public function X()
{
var object1:Object = {a: "1", b: "2"};
var object2:Object = object1;
object2.c = 3;
trace("Object 2:");
for (var name:String in object2)
{
trace("Name: " + name + " = " + object2[name]);
}
trace("Object 1:");
for (var name:String in object1)
{
trace("Name: " + name + " = " + object1[name]);
}
}
}
}
......输出:
Object 2:
Name: a = 1
Name: c = 3
Name: b = 2
Object 1:
Name: a = 1
Name: c = 3
Name: b = 2
如果您在询问是否可以克隆对象或动态类,可以使用如下函数:
public function cloneObject(object:Object):Object
{
var newObject:Object = {};
for (var name:String in object)
{
newObject[name] = object[name];
}
return newObject;
}
