js闭包运用

function Person(){    
    var name = "default";       
       
    return {    
       getName : function(){    
           return name;    
       },    
       setName : function(newName){    
           name = newName;    
       }    
    }    
};    
     
     
var john = Person();    
print(john.getName());    
john.setName("john");    
print(john.getName());    
     
var jack = Person();    
print(jack.getName());    
jack.setName("jack");    
print(jack.getName());    
   
运行结果如下：

john  
default  
jack
