新动作脚本

Question

我试图创建一个添加用户新用户（）的简单表单。但是当我构建它时，我在同一行上得到两个错误。

调用可能未定义的方法用户。并且找不到类型或者不是编译时间常量。

    public class Person 
    { 
     public var fname:String; 

     public var lname:String; 

     public var dob:Date;

    public class User extends Person

     public var salt:String; 

     public var created_at:Date;

    } 
} 

Answer 1

你不能在同一个文件。作为两个公共类定义，并注意该文件必须具有相同的名称作为内部的公共类。

在你的情况下，你将有2个文件，一个名为Person.as，另一个名为User.as.你必须

Person.as

package me.entities 
{ 
    public class Person 
    { 
     public var fname:String; 

     public var lname:String; 

     public var dob:Date; 
    } 
} 

User.as

package me.entities 
{ 
    public class User extends Person 
    { 
     public var crypted_password:String; 

     public var salt:String; 

     public var created_at:Date; 

     public var last_login:Date; 

     public var last_ip:String; 

    } 
}
