JAVASCRIPT经典例子之二

function Person(name, age) {
    //实例属性
    this.name = "this:"+name;
    //实例属性
    this.age = 1000+age;
    //静态属性
    Person.age = this.age;
    
    this.getName = function() { return this.name; };

    this.setName = function(newName) { this.name = newName; };

    this.getAge = function() { return this.age; };

    this.setAge = function(newAge) { this.age = newAge; };

}

var ray = new Person("Ray", 31);

alert(ray.getName());//display:"this:Ray"

alert(ray.getAge());//display:"1031"

ray.setName("Younger Ray");

// Instant rejuvenation!

ray.setAge(22);

alert(ray.getName() + " is now " + ray.getAge() + 

      " years old.");//display:"Younger Ray is now 22 years old."
      
alert(Person.age);//display:"1031"
