JavaScript 面向对象编程

// 原型对象:
var Student = {
    name: ‘Robot‘,
    height: 1.2,
    run: function () {
        console.log(this.name + ‘ is running...‘);
    }
};

function createStudent(name) {
    // 基于Student原型创建一个新对象:
    var s = Object.create(Student);
    // 初始化新对象:
    s.name = name;
    return s;
}

var xiaoming = createStudent(‘小明‘);
xiaoming.run(); // 小明 is running...
xiaoming.__proto__ === Student; // true
