Javascript中的混合继承

混合继承 既继承模板 也继承原型对象

//父类
function Father(name,age){
this.name =  name;
this.age = age;

}
//父类的原型对象属性
Father.prototype.id = 10;
//子类
function Son(name,age,job){
this.job = job;
Father.apply(this,[name,age]);//借用构造函数，继承父类模板
}

Son.prototype = new Father();//继承父类原型对象
var xiaoming  = new Son('张丹',25,'程序员');

alert(xiaoming.id);
alert(xiaoming.name+'今年'+xiaoming.age+'从事'+xiaoming.job+'工作');
