javascript對象冒充示例
<script type="text/javascript">
function Animal(name,age){
this.name=name;
this.age=age;
this.eat=function(){
alert("動物可以吃東西");
}
}
function Dog(name,age){
//把Animal構(gòu)造函數(shù)賦給this.an
this.an=Animal;
//運(yùn)行調(diào)用@！?。。》浅Ｖ匾?/div>
this.an(name,age);
}
var dog=new Dog("小白",2);
alert(dog.name);
dog.eat();
</script>
