javaScript面向对像

1.创建对象

<script type="text/javascript">
    function Flower(name,addre) {
        this.name=name;
        this.addre=addre;
        this.showName=myName;
    }
    function  myName() {
        alert(this.name);
    }
    var fi=new Flower("牡丹","洛阳");
    fi.showName();
</script>

　　

<script type="text/javascript">
    var fowlor={
        name:"牡丹",
        showName:function () {
            alert(fowlor.name);

        }

    };
    fowlor.showName();

</script>

　

<script type="text/javascript">
    function Flower() {

    }
    Flower.prototype.name="牡丹花";
    Flower.prototype.addre="洛阳";
    Flower.prototype.showName=function () {
        alert(this.name)
    }
    var flag=Flower.prototype.constructor==Flower;
    alert(flag);
    var flower1=new Flower();
    flower1.showName();
</script>

　　

<script type="text/javascript">
    function  Humens() {
        this.foot=2;
    }
    Humens.prototype.getFoot=function () {
        return this.foot;
    }
    function Man() {
        this.hade=1;
    }
    Man.prototype=new Humens();
    Man.prototype.getHead=function () {
        return this.head;
    }
    var man1=new Man();
    alert(man1.foot);
</script>

　　

<script type="text/javascript">
    function Humens() {
        this.sport=["baskball","baseball","pingpong"];

    }
    function Man() {
        Humens.call(this);
    }
    Man.prototype=new Humens();
    var man1=new Man();
    man1.sport.push("tang");
    alert(man1.sport);
    var man2=new Man();
    alert(man2.sport);
