JS——对象创建

1、原始创建

<script>

    person = new Object();//不要var

    person.firstname = "Bill";

    person.lastname = "Gates";

    person.age = 56;

    person.eyecolor = "blue";

    person.say = function () {

        console.log(person.firstname);

    }

    person.say();//Bill

</script>

<script>

    var person = {

        firstname: "John",

        lastname: "Doe",

        age: 50,

        eyecolor: "blue",

        say: function () {

            console.log(this.firstname);

        }

    };

    person.say();//John

</script>

2、进阶版本

<script>

    function CreatePserson(name) {

        var person = new Object();

        person.name = name;

        person.sayHi = function () {

            console.log(this.name);

        }

        return person;

    }

    var stu1 = CreatePserson("wu");

    stu1.sayHi();//wu

</script>

3、最终版本

<script>

    function Person(name, age) {

        this.name = name;

        this.age = age;

        this.say = function () {

            console.log(this.name + "===" + this.age);

        }

    }

    var per = new Person("wu",27);

    per.say();//wu===27

</script>
