1.工廠模式

function Person(name,age,job) {
        //創(chuàng)建一個(gè)空對(duì)象
        var o = {};

        o.name = name;
        o.age = age;
        o.job = job;

        o.showName = function () {
            alert(this.name);
        };
        o.showName = function () {
            alert(this.age);
        };
        o.showName = function () {
            alert(this.job);
        };
        return o;
    }
    var Tom = Person('tom',18,'程序員');
    Tom.showName();

2.構(gòu)造函數(shù)

function Person(name,age,job) {
        this.name = name;
        this.age = age;
        this.job = job;

        this.showName = function () {
            alert(this.name);
        };
        this.showAge = function () {
            alert(this.age);
        };
        this.showJob = function () {
            alert(this.job);
        };
    }
    var Bob = new Person('bob',18,'產(chǎn)品汪');
    Bob.showName();

3.原型模式

function Person(name,age,job) {
        this.name = name;
        this.age = age;
        this.job = job;
    }
    // prototype原型
    Person.prototype.showName = function () {
        alert(this.name);
    };
    Person.prototype.showAge = function () {
        alert(this.age);
    };
    Person.prototype.showJob = function () {
        alert(this.job);
    };
    var Lucy = new Person('Lucy',19,'測(cè)試鼠');
    alert(Lucy.showName());
