javascript中的对象创建方式

 

83.  自定义对象

function Person(){

}

var p = new Person();

p.name = "张三";

p.age = 20;

alert(p.name + ", " + p.age);

 

 

function Person(name,age){

this.name = name;

this.age = age;

}

var p = new Person("李四",30);

alert(p.name + ", " + p.age);

 

 

84.  Object对象，利用Object对象，可以省得写function 对象了。

var person = new Object();

person.name = "张三";

person.age = 20;

alert(person["name"] + "," + person["age"]);

 

 

 

<script>

var v ={id:12,name:"zhangsan"};

alert(v.name);

  </script>
