单体创建对象

<script type="text/javascript">
        var tom = {
            name:'tom',
            age : 18,
            showname:function () {
                alert(this.name);//this相当于self
            },
            showAge:function () {
                alert(this.age);
            }

        };//对象
        console.log(tom.name);
        console.log(tom.age);
        tom.showAge();
        tom.showname();//函数的方法会弹出来
    </script>

工厂模式创建对象

    <script type="text/javascript">
        function Person(name,age,job) {
            //var o = new Object();//创建一个空对象
            var o ={};//创建一个空对象
            o.name = name;
            o.age = age;
            o.job = job;

            o.showName = function () {
                alert(this.name)
            }
            o.showAge = function () {
                alert(this.age)
            }
            o.showJob = function () {
                alert(this.job)
            }
            return o;
        }
        var Tom = Person('tom',18,'程序员');
        Tom.showJob();//函数的调用会弹出框
        var jack = Person('jack',18,'老师');
        jack.showJob();
    </script>
