// 寄生组合式继承 // 其基本思路是通过借用构造函数来继承属性,通过原型链的混成形式来继承方法,就是为了不必为了子类型的原型去调用父类型的构造函数 function inheritPrototype(superPerson,person) { var prototype=Object.create(person.prototype); prototype.construtor = superPerson; superPerson.prototype = prototype; } function Person(name) { this.name = name; this.frieds = ["Jack", "John", "Kim"]; } Person.prototype.getName = function(){ console.log(this.name); }; function SuperPerson(name,sex){ Person.call(this,name); this.sex = sex; } inheritPrototype(SuperPerson,Person); SuperPerson.prototype.getSex = function(){ console.log(this.sex); }; var Tom=new SuperPerson("Tom","man"); Tom.getName();//Tom
