这是从达人翻译的文章中截的，不过源程序有错误，偶改了一下。顺手挂上原教程和源文件(这可是一颗一颗看着flashPaper打的啊！)。上次听的一个c#的讲座，用的也是这个vehicle和car；呵呵，看如何用class驱动我们可爱的flash。
工程有两个类：Vehicle（superClass）和Car（subClass）；
class Vehiche{
private var _nPassengers:Number;
public var _nMiles:Number;
public var _nInterval:Number;
function Vehicle(nPassengers:Number,nMiles:Number) {
_nPassengers=nPassengers;
_nMiles=nMiles;
}
...................}
class Car extends Vehiche{
private var _sMake:String;
private var _sMode1:String;
private var _nYear:Number;
function Car(sMake:String ,sMode1:String,nYear:Number,class Car extends Vehiche{
private var _sMake:String;
private var _sMode1:String;
private var _nYear:Number;
function Car(sMake:String ,sMode1:String,nYear:Number,nPassengers:Number,nMiles:Number) {
super.Vehicle(nPassengers,nMiles);//超类
//_nPassengers=nPassengers;
//_nMiles=nMiles;
_sMake=sMake;
_sMode1=sMode1;
year=nYear;
}Number,nMiles:Number) {
super(nPassengers,nMiles);
_sMake=sMake;
_sMode1=sMode1;
year=nYear;
}
...................}
private var _nPassengers:Number;
public var _nMiles:Number;
public var _nInterval:Number;
function Vehicle(nPassengers:Number,nMiles:Number) {
_nPassengers=nPassengers;
_nMiles=nMiles;
}
...................}
class Car extends Vehiche{
private var _sMake:String;
private var _sMode1:String;
private var _nYear:Number;
function Car(sMake:String ,sMode1:String,nYear:Number,class Car extends Vehiche{
private var _sMake:String;
private var _sMode1:String;
private var _nYear:Number;
function Car(sMake:String ,sMode1:String,nYear:Number,nPassengers:Number,nMiles:Number) {
super.Vehicle(nPassengers,nMiles);//超类
//_nPassengers=nPassengers;
//_nMiles=nMiles;
_sMake=sMake;
_sMode1=sMode1;
year=nYear;
}Number,nMiles:Number) {
super(nPassengers,nMiles);
_sMake=sMake;
_sMode1=sMode1;
year=nYear;
}
...................}
这是原文，Car类中的构造函数中要继承Vehicle的构造函数中的nPassengers,nMiles参数。用super（nPassengers,nMiles）；
结果我敲完了一run，不行，trace（car.nMiles）=undefined;
仔细看完了文档后才清楚了一点super的用法，于是改为
super.Vehicle(nPassengers,nMiles);
结果成功，哈哈，被达人玩了了一通，想想还是自己好好从本质上下手的好，学oop看java吧，呵呵 ！
