js中的变量封装(2)

 // [...]  
 }, 
 getMemberDetails:function(){ 
 // [...]  
 } 
 } 
 }(); 
 // myApplication.createMember() and  
 // myApplication.getMemberDetails() now works. 
var myApplication = function(){
 var name = 'Chris';
 var age = '34';
 var status = 'single';
 return{
 createMember:function(){
 // [...]
 },
 getMemberDetails:function(){
 // [...]
 }
 }
 }();
 // myApplication.createMember() and
 // myApplication.getMemberDetails() now works.

 

这种做法称之为：a module pattern 或者 singleton

在YUI中用得非常多，进一步优化：

[javascript]
var myApplication = function(){ 
 var name = 'Chris'; 
 var age = '34'; 
 var status = 'single'; 
 function createMember(){ 
 // [...]  
 } 
 function getMemberDetails(){ 
 // [...]  
 } 
 return{ 
 create:createMember, 
 get:getMemberDetails 
 } 
 }(); 
 //myApplication.get() and myApplication.create() now work. 
var myApplication = function(){
 var name = 'Chris';
 var age = '34';
 var status = 'single';
 function createMember(){
 // [...]
 }
 function getMemberDetails(){
 // [...]
 }
 return{
 create:createMember,
 get:getMemberDetails
 }
 }();
 //myApplication.get() and myApplication.create() now work.
