Question

我正在尝试创建一个添加用户新User（）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User。和类型未找到或是不是编译时常量。

Answer 1

您不能在同一.as文件中有两个公共类定义，并注意该文件必须与其中的公共类具有相同的名称。

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;

    }
}
