1.将模块整体放在函数里

1 function buildMonthNameModule() { 2     var names = ["January ", "February", "March", "April", "May ", "June ", "July", "August ", "September ", "October ", "November", "December"]; 3     function getMonthName(number) { 4         return names[number]; 5     } 6     function getMonthNumber(name) { 7         for (var number = 0; number < names.length; number++) { 8             if (names[number] == name) { 9                 return number;10             }11         }12     }13     window.getMonthName = getMonthName;14     window.getMonthNumber = getMonthNumber;15 }16 buildMonthNameModule();

2.模块对象

1 var days = (function() { 2     var names = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]; 3     return { 4         getDayName: function(number) { 5             return names[number]; 6         }, 7         getDayNumber: function(name) { 8             for (var number = 0; number < names.length; number++) { 9                 if (names[number] == name) {10                     return number;11                 }12             }13         }14     };15 })();
