JS模式之单例模式基本用法

本文实例讲述了JS模式之单例模式基本用法。分享给大家供大家参考。具体如下：

//singleton

var SingletonTester = (function(){

function Singleton(options){

options = options || {};

this.name = "SingletonTester";

this.pointX = options.pointX || 6;

this.pointY = options.pointY || 10;

};

var instance;

var _static = {

name : "SingletonTester",

getInstance : function(options){

if(instance === undefined){

instance = new Singleton(options)

};

return instance;

}

};

return _static;

})();

希望本文所述对大家的javascript程序设计有所帮助。
